1. Write an essay on the characteristics of turtles

My family has a cute little turtle, which looks very cute. A small and exquisite head, a pair of small black and translucent eyes, a pointed nose, a mouth so small that it seems invisible, and a thick layer of skin on the neck, as if wearing a scarf. It carries a heavy "house" on its back. Whenever it encounters danger, its hands and feet will "swipe" and retract. It is really like a turtle with its head down. The first time I saw it, I loved it.

It is lazy all day long, but it enjoys life very much. Whenever the sun shines into the house, it will slowly climb up the hillside I made specially for it with sand, squint its eyes, spread its legs, and enjoy the sunbathing motionless. At this time, I would make a little joke with it and reach out my hand to pretend to hit it. It was so frightened that its head shrank, its body retreated, and it fell into the water with a splash.

It is also very timid. When someone stands in front of it, it keeps shrinking in its "house", pretending to be asleep and refusing to come out. After we had walked a long way, it slowly stretched out its head, looked around, and then looked at us with a puzzled look, as if to say: "Master, did someone come just now? Why didn't you Introduce me? ”

The way it eats is also very interesting. Whenever I feed it, before I put the meat down, it seems to smell the aroma of the meat, and then stretches its neck and pokes its head out, opening its small mouth and waiting for me to feed it. At this time, I would keep tempting it with meat, and it would look at me with begging eyes, as if to say: "Little master, stop playing, I'm starving." As soon as my heart softened, I would Throwing the meat down, it opened its mouth, picked up the meat accurately, then grabbed the meat with its front feet and ate it with relish.

This is my little turtle, isn’t it cute!

I have a little turtle, which was given to me by my cousin on my birthday. It has a small, long head, short limbs, a thin tail, and a hard shell on its back, really like a little soldier wearing armor. It looks like a stone, but when it sticks its head out, it becomes a complete turtle. The most conspicuous part of its head is that its face is extremely red, as if it had drunk too much wedding wine. At first I didn't know what it liked to eat, so I did an experiment. I chopped up some meat and put it in the fish tank. It immediately crawled over, nudged it with the tip of its nose, and then retracted its head and limbs into its shell. After a few times, it confirmed that the food was not dangerous and swallowed it in one gulp. I also experimented with shrimp skin and shrimp meat, and it turned out that it was more delicious than meat! Sometimes it is vegetarian, and I put down some lettuce leaves. If it is hungry, it will take a bite; if it is not hungry, it will not even smell it. Whenever I feed loaches and shrimps to the little turtle, it always pounces on them ferociously, but every time it hits the glass with its claws in the air. It hasn't caught the loaches and shrimps yet, because the loaches and shrimps are too clever. . I couldn't help laughing. The little turtle has to sleep in a place without water. When it sleeps, it does not move, and its head, limbs, and tail are all tucked into the shell. The little turtle is very fast when he goes up the stairs. One step, two steps, three steps to get there. The little turtle didn't take the stairs when he went down. He jumped directly from the place where there were no stairs. It seemed like a perfect jump, but every time he fell with his paws in the air, which made me laugh. It was so funny! If you change the water, that would be terrible. It always crawled east and west. I remember once, it almost crawled into the sewer. One time during Labor Day, our family went to Suzhou and didn't come home for five days. When we came back, we could only see it swimming slowly in the fish tank. After I gave it a "big meal", I immediately changed the water, and it crawled east and west again, as if to say: "It's been a long time since I've breathed fresh air." This little turtle stayed with me for a long time. Time, this year this cute little guy finally left me with the autumn wind. I couldn't bear to throw it into the trash can hastily, so I asked two classmates from the biology group to make it into a specimen and put it in my library. Next to the desk. Little turtle, you will always be my best friend!

I hope it can help you if you are not satisfied. 2. The morphological characteristics of the turtle. :

The head is small, the snout is blunt, there are yellow and green vertical stripes on the head and neck, there is a pair of red patches behind the eyes, the carapace is flat, and there is a circular green ring on each scute. The pattern is not serrated. The plastron is light yellow and has a black ring pattern, which is different for each turtle. The toes and fingers are richly webbed. It has large black spots, fierce personality, flexible movements, relatively smooth skin, thin body and thick skirt, and golden color of fat. It has surpassed wild turtle in terms of taste, nutrition, safety and other indicators. p>

Main organs and physiological functions:

1. Skin

The biggest feature of turtle skin (except the front end of the head) is roughness, and the epidermis has fine granular or small The massive scales protect the dermis, reduce friction with the outside world and reduce the evaporation of water in the body.

2. The turtle's breathing method

The turtle breathes by stretching and contracting its neck and limbs. It directly affects the size of its abdominal cavity, thereby affecting the expansion and contraction of the lungs. When a turtle breathes, it exhales first and then inhales. This special breathing method is called "pharyngeal" breathing, also known as "turtle inhalation".

The respiratory movement process of the turtle can be observed from the contraction changes of the skin membrane of the turtle's hind limb fossa.

3. Smell

There are two nostrils on the human body, but only one nasal cavity. The bones in the nostrils are covered with epithelial mucosa and have the function of smell. The pirinasal organ is their main olfactory organ. Because when turtles are looking for food or crawling, they always extend their heads and necks very long to explore the smell and then decide the direction to move forward.

4. Vision

The turtle's eye structure is very typical. Its cornea is convex, the lens is rounder, and the ciliary muscles are well developed. The curvature of the lens can be adjusted to adjust the visual distance, because , the turtle's field of view is generally very wide, but the clarity is poor. Therefore, turtles are more sensitive to moving objects, but slow to respond to still objects. According to experiments by British zoologists, most turtles can distinguish colors like humans, and are especially sensitive to red and white.

5. Hearing

The hearing organs of turtles are only the ears and middle ears, but no external ears. And the outermost part is the eardrum. Therefore, turtles are insensitive to airborne sounds. It is more sensitive to vibrations conducted by the ground. Therefore, generally speaking, turtles are almost considered to be both dumb and deaf animals.

Overview:

It is named because there are two pairs of thick red stripes on both sides of the back of its head. The red-eared turtle is more commonly known as the Brazilian turtle in the market. Most species are found in Brazil, and a few species are found in the Mississippi River in the United States. The first one introduced was indeed the Brazilian turtle. It looks like the red-eared turtle but does not have red ears. Now it has been replaced by the red-eared turtle and people call the red-eared turtle the Brazilian turtle. This type has the typical red stripes on the sides of the head and sometimes a red spot on the top of the head. The red stripes sometimes break into two or three spots and vary in color from orange to deep red. Some red-eared sliders don't have these red stripes! A typical hatchling red-eared slider has an attractive green carapace and skin. The carapace is covered with a perfect pattern of yellow-green to dark green stripes. As the turtle grows, the color of the shell changes. In young adults, the green undertone is replaced by yellow, eventually becoming a darker brown-olive color. The pattern on the shell consists of black lines, stripes, and smoke-like patches, sometimes mixed with white, yellow, and even red spots. In older individuals, their carapace appears more uniform due to reduced differences in pattern and carapace color. 3. Write a 300-word essay about turtles

During the summer vacation, my father bought me two small turtles. The little turtle has brown skin. The yellow patterns on its head and neck are faintly visible. Its small but energetic gray eyes look at the world around it curiously. Its light yellow eyelids open and close. It always carries a small house on its back. .

I often play with the little turtle and put it on the ground with its legs in the air. At first it remained motionless. After a while, when it saw no movement, it slowly stretched out its tightened head, looked left and right, and when it saw that there was no danger, it stretched out its limbs and pushed its head hard, only to hear "bah" With a sound, it turned over, then spread its short limbs and crawled towards the dark place, which was very interesting. A turtle can survive without eating for a long time, but I don't want it to go hungry. It eats quite a variety of foods. It likes to eat meat, and it also likes to eat live animals. I often feed it some fish intestines, minced fish, small fish, shrimps, and snail meat. Sometimes I even dig out some earthworms to feed it. The turtle's sense of smell is very sensitive. Whenever I put earthworms in the fish tank, it seems very active and happy.

I like the little turtle because it has many interesting and interesting things that bring me joy. I feel the joy of life and the vitality of life from it. 4. For an essay describing pets, describe a turtle in about 300 words

My family has a very cute little turtle. It was bought by my mother and I at the pet store a few days ago.

It looks very small. Although I forgot to ask how old it was when I bought it, I guess it is only two or three years old at most.

It has a small head with a pair of small black eyes embedded in it, and there is a gold rim around the eyes! Below the eyes is the mouth, which is also very small. Although he has a small mouth, my grandfather said that turtles can bite wires! There is a hard shell on its back. If you look carefully, you can see that there are many regular hexagons on the hard shell. Its limbs are very short and it walks very slowly, but when it encounters an enemy, it quickly retracts its head and limbs together with a thin tail into its shell, so that the enemy cannot attack it.

The way it sleeps is also very cute. When sleeping, it also retracts its head and limbs into its shell, as if it encounters an enemy.

If you put some turtle food when feeding it, it will usually not eat it until it observes the surroundings to make sure everything is safe before eating secretly. Grandpa also told me that turtles can go several days without eating and can live for hundreds of years!

When the little turtle moves, it will get some air and walk around in the breeding basin. It will move for a while and then stop. This is probably the "movement" of the turtle!

I named it "Hui Hui" because it is gray all over. I love it very much and take good care of it every day.

Do you also like this little turtle "Hui Hui"? 5. Write an observation essay about a turtle, no less than 300 words

The Greedy Little Turtle Today, I had nothing to do, so I went to see the little turtle "Baker" and saw only its head, feet and tail. He shrank up and didn't eat anything. I thought he must be too lonely! So, I ran out and bought another turtle, along with two boxes of feed. This new turtle "Kham" was the same as "Baker", except that the tail was a little bigger, but they were part of the big family of Brazilian turtles. .

After I got home, I put 'Kham' down, but 'Baker' didn't respond. When I dropped the turtle food, 'Baker' rushed forward and wanted to eat! I watched him touch the feed and make sure it was soft and hard before eating. "Baker" only eats soft food. It swallows the feed that is one to two millimeters long. It needs to grind the feed with its mouth over two millimeters before eating. From time to time, it will be exposed. One point. I smiled. It seemed that "Baker" was hungry! At this time, "Kham" was walking leisurely in the water. The two turtles were not hostile at all and got along well.

I feed the little turtles once a week. One turtle eats about four pellets at a time. I have two of them, and eight pellets a week are enough. Their stomachs are really small. Turtles have the ability to control their eating. They will not eat when they are full. Like a fish, it will eat even when it is full.

I stared at it for two and a half hours, then I rubbed my eyes and went back to my room. At noon today, I went to see the little turtles, and they were sleeping like pigs in the dark balcony! I was surprised, wasn't it just a little dark in the daytime?

I turned on the light, but there was nothing. After a while, the little turtle's eyes opened and slowly became active. When I turned off the light, the little turtle's limbs did not move. A few minutes later, a big shell came out of its head. After a while, there was no movement. It turned out that as long as the surroundings were dark, , it will sleep, I thought they only sleep at night! If you pick up the little turtle when it is sleeping, it will stay for a while; then its limbs will swing slowly, but its eyes will not open; if you don't let it go, He wiggles his eyes wildly; then stops and gathers enough strength; at the last moment, he will use the "Nine Eagle White Bone Claws"! You have to put it down. Both turtles sleep for about two hours at a time. The room was dark all day long, and my "Baker" slept for three days and three nights! Hush - the little turtle was woken up!

Crab turtle, I have a whim. I thought: "How about putting some kind of "shirt" on the little turtle? Make one out of cloth? I can do it, but it's too ugly, and it's not good if it gets wet.

Color? Don't think about it, if you paint it on it and look like a monster, they themselves will be scared to death by this "clothes"! I "scanned" everywhere, looking for the target. Suddenly my eyes lit up and I spotted a clean, washed, and sun-dried, solid crab shell! I took two rubber bands, arranged them on "Khan" and held them down? Then I put the "armor" on, wow! How mighty! The thorns on the edges are shiny, so cool! I picked up another crab shell and was about to put it on "Baker" when "Baker" moved around and almost broke my rubber band. It took a lot of effort to put the "Stand Armor" on Going up, the two crab turtles were happy and mighty, seeming to say: "Who dares to fight me.

"

! "Lightning" Little Turtle You must have heard the story of "The Tortoise and the Hare". The tortoise in it crawls very slowly. Indeed, in the eyes of the hare, it looks very slow, but in reality it is not like this. The turtle's head, feet, and tail can stretch freely and very quickly. Let's start with the swimming speed. Don't be surprised when I tell you that my turtle can swim between seven and ten centimeters in one second. Why can it swim? So fast? This is because each of its four feet is like a fan. The toes are brackets, and each bracket is connected with a thin piece of skin in the middle. This increases the contact area with water and increases the resistance. If you push hard, you can swim. Of course it's fast, but it's very laborious.

The same is true for the feet of ducks and geese. Another point is that the turtle does not need to control the sinking and floating of its body. It is not a "multifunctional submarine". With its weight, it can float easily in the water unless it swims down by itself.

The turtle is a "top-light and foot-heavy" guy, which provides great benefits for its ventilation. Fighting between little turtle classmates is inevitable, but it depends on the relationship between you and me; wolves living in groups seem to be united and friendly, but they will also kill each other for the throne; in our minds, the docile little turtles will also fight, maybe That wasn't really a fight, it was a "turtle fight."

The fight between the little turtles will not cause harm to each other. The most serious ones will only scratch a few tenths of a millimeter and bleed a little bit, but this phenomenon rarely occurs. Under normal circumstances, little turtles will have such a struggle. "Kham" rushes to "Baker", and "Baker" is hit. "Kham" continues to rush forward, burying his head under "Baker's" belly, and "Baker" "The front half is tilted up, and the forelimbs are swinging around, but they can't touch anything at all. The same is true for the back. At this time, "Khan" will push "Baker"'s belly, causing it to somersault and fall behind itself. "Baker" When you lose, a game is over.

My family has two cute and interesting tortoises. One is a female, I call it Honghong, and the other is a male, I call it Mingming. The color of the tortoise is dark. It's green, with a triangular head, and small mung bean-like eyes that are rolling around. The hard shell really looks like the armor worn by a general. What impressed me the most was the tortoise doing somersaults. I first turned the tortoise over on all fours, and then After waiting patiently, it didn't take long for the tortoise to start moving. First it rested its head on the ground, and then its front feet and hind paws also rested on the ground. With a hard step, it turned over. However, sometimes it accidentally Ben Zhong's body swayed from side to side, and his legs were in the air again, but he was not discouraged. After several efforts, he still turned over. I never thought that tortoises also have such perseverance! My tortoises are so funny and cute. I like my two tortoises so much! Last night, after dinner, I had nothing to do, so I went out to visit the night market with my dad. We came to the center of the night market, and I saw a stall specializing in small animals. I looked at it seriously. There was a turtle on the stall; Birds; and goldfish and white mice. I found a turtle that was very cute. It raised its head high and retracted its limbs and tail into its shell. It was also very lazy. I just looked at it for a while, and it fell asleep. His personality is exactly the same as mine.

I asked my father to pay for it. 6. A 300-word essay about the little turtle

My family has two little turtles. The smaller one is called "Doudou" and the larger one is called "Beibei". They are my favorite "little friends".

Look, how cute they are! It has small bean-like eyes, a small "V" shaped mouth, four short little feet, and a small tail only about one centimeter long. The most distinctive thing is the "armor" they wear - their back shells. The oval-shaped hard shell is neatly divided into 13 prismatic patterns, three in a row in the middle, and the remaining ten pieces form a large oval. There is also a decorative edge of an oval composed of small patterns. It looks very cute.

Even though the little turtle has a small mouth, it can eat a lot! One morning, I cut off six small pieces of lean meat, picked up a piece and shook it in front of "Doudou"'s mouth. It stretched out its head and sniffed, and immediately opened its mouth and bit into the lean meat. The round little He looked around with vigilant eyes, and saw the slow-responsive "Beibei" closing his eyes leisurely and concentrating, without noticing his "treasure" at all. Then he took the meat far away from "Beibei" and tasted it with confidence. He saw that he "kicked" the lean meat with his front paws, then bit the other end of the lean meat with his mouth, and pulled it out hard. The lean meat was quickly separated into two sides, and it immediately ate the half in its mouth with a "tsk" sound, and then swallowed the other half on its paws... "Huh, you selfish little guy, Eat all the delicious food and give nothing to your companions!" I thought angrily on the sidelines. In order to punish "Doudou", I put another piece of lean meat in front of "Beibei" and let him eat it, so that "Beibei" also had a good meal... After eating and drinking, the little turtle retracted its head into its mouth. They sleep comfortably in the "armor", they know how to enjoy it!

There is nothing more interesting than watching a turtle swim. I filled the basin with water, and they started to play in the water. Their four little paws were like two pairs of small paddles, paddling constantly, and their little tails were swinging rhythmically. Get up, leaving a faint trace where you swam, and it disappeared after a while. The little turtle would still put its head out of the water from time to time, open its mouth slightly, as if breathing, and then get back into the water. Seeing these scenes, I thought: Do small turtles, like humans, need to come out of the water to take a breath after being in the water for a long time? I looked up books with this question in mind, and learned that turtles breathe with their lungs, and understood that if they stay underwater for a long time, they have to swim up to the surface to take a breath.

I heard from my brother that little turtles hibernate in winter. Now winter is coming. I want to feed the little turtles well and let them sleep beautifully all winter.

I love all kinds of small animals, especially this little turtle with an unspectacular appearance and an unknown appearance. They bring me fun and become my "good companions".

Hope to adopt 7. 300-word essay on little turtle

How I look forward to my little turtle coming back soon!

Looking at the empty small pool, I recalled that day four years ago.

My father and I came to the market and saw someone selling small turtles. Dad bought me one

After I got home, I kept it in a small pond.

Look, the little turtle is so cute! It often stretches its neck and looks around. Sometimes it

stretches out its limbs and wanders awkwardly in the small pool.

Whenever I have free time, I find a lot of food, some vegetarian and some meat.

Put it in front of its eyes, and it stretches its neck and picks it up. Come and eat those meaty things. When it is full, I will "invite" it out of the small pool and put it on the corridor to play with it. Sometimes, I would put some gadgets on its hard

back, and it would carry them all over the house. Sometimes I turn it over

so that it's on all fours.

At this time, it will first stretch its limbs, then extend its neck, push it hard on the ground, and use all its strength to turn over.

However, something unfortunate happened. One day, the little turtle was not in the small pool. I searched all over the house, but I still couldn't find my cute little turtle.

I hope it will not be snatched away by a cat or become someone else's meal. I hope it can

return to the embrace of nature.

I hope that one day, it will come back to visit me, a good partner who has been with it for four years.

It wears "armor", which is composed of many patterns of different sizes. The abdomen is protected by a whole hard shell. The hard shell is horny and very strong. It was "unscathed" when I stepped on it. It has four legs with sharp claws on its toes. The most eye-catching thing is its head: the head is triangular in shape, with a pair of bright eyes; there is a layer of wrinkled skin on the neck, which allows the neck to stretch. When it is stretched out, it is long, and when it is retracted into the shell, it is a little. I can't see my son either.

Lele was very afraid of me when he first came to my house. He would always retract his head into his shell. I simply thought it was a headless turtle. However, whenever I walked away, it would stick out its head, look around, and crawl all over the ground.

Now, it plays with me often. One time, I was doing my homework, and suddenly I heard a "plop" and "plop" sound behind the door. I was startled. When I opened the door, I saw that it was a little turtle scratching at the door. Another time, I was watching TV. I turned my head and saw Lele playing next to me, and kept trying to scratch my pants with her claws. What a "little bad guy".

My Lele is so cute!

Then write about its appearance in another paragraph. And so on, and then you can write about simple times, such as taking it to play by the river, writing about how it eats, and finally expressing your feelings for it. 8. 100-point reward: describe the little Essay about a turtle, 300 words

The little turtle usually likes to sleep in humid places. I put it in the pool, and when it was hungry, it climbed out of the pool and stretched its neck. It looked at me as if to say: "I'm hungry, give me something to eat quickly." At this time, I put it in the basin, poured water, put meat and rice grains on it.
