What small animals have special skills?

Small animals such as chameleons, geckos, bats, pigeons and torpedoes all have their own specialties.

Chameleon-change the color of the body

Specialty: Good at changing the color of your body at any time with the change of environment. It is good for hiding yourself and catching prey. One view is that the pigment cells in the skin expand or contract under the control of the autonomic nervous system. Another view is that recent studies have found that discoloration is not caused by pigment cells, but by adjusting the nanocrystals on the skin surface to change the refraction of light.

Second, the gecko-broken tail "self-defense"

Specialty: When pulled by external force or injured by the enemy, the tail muscles contract strongly, resulting in the tail breaking. Zoology is called "self-cutting" The newly broken caudal nerve is not dead, and it continues to move. You can use separation to protect yourself from it. Gecko has a hormone that can regenerate its tail. When the gecko's tail is broken, it will secrete this hormone to make the tail grow. When it grows, it will stop secreting.

Third, bats-ultrasonic positioning to kill prey

Special skills: Bats rely on sound waves to find their way and hunt. They emit sound waves that humans cannot hear. When the sound wave meets an object, it will return like an echo, so that bats can tell whether the object is moving or stationary and how far it is. Use ultrasonic echo positioning signals to search for food, detect distance, determine targets, avoid obstacles and escape from enemies.

Fourth, pigeons-navigation

Special skills: Scientists believe that pigeons have a "space map" on their heads, which allows them to fly to unfamiliar areas and know exactly where they are going. This discovery replaces the current theory that pigeons compare their dovecotes with their position coordinates, and then systematically reduce the differences between them and find their way home. Previous theories compared the flight of pigeons to flying robots.

Fifth, torpedo launches "self-defense"

Special skills: The main center of the generator is the nerve part of the organ. Torpedo can discharge at will, and the discharge time and intensity can be controlled by itself. Torpedo can generate electricity and use the generated current to kill small animals such as fish and shrimp in the water. It is a means of preying and attacking the enemy.
