Quayle's physiology

The overall figure of Quelli people is slightly shorter and thinner than that of human beings. Quilli is an endoskeleton with lips, teeth, two eyes, eyelids and lacrimal glands. They have three stout fingers, including a thumb and two forefingers, and three toes on each foot. Compared with humans and Asari people, their calves are obviously bent backwards. Except for the legs and hands, the general shape of Quelli people's bodies and the difference between sexes are similar to those of humans. The ears of Quelli people, or organs similar to ears, are significantly different from those of humans.

The most obvious feature of Queli people's physiological structure is their fragile immune system, which is due to living in a sterile environment for centuries. As a result, all Quelli people must wear highly complex protective clothing to protect them from infection caused by illness or injury. The protective clothing of Quelli people can be isolated independently in the event of rupture or similar damage, so as to prevent the spread of pollutants (just like a ship uses a partition when its hull is damaged).

The Quelli people's immune system is inherently weak, because pathogens are rare in the ecological circle of their home planet. Furthermore, the few local viruses and pathogens are beneficial to them. After several generations of breeding in the immigrant fleet, the immune system of the Quelli people is even more declining because they live in the sterile environment of the immigrant fleet all the year round. Therefore, Quelli people will be vaccinated with a large number of different vaccines and other immune measures to fight the disease. However, even in a clean environment, Quelli people will not take off their protective clothing for no reason.

If you want to take off your protective clothing, Quelli people must take antibiotics, immune enhancers, herbs and so on to ensure safety, but even so, there are always risks. Therefore, it is very difficult for Quelli people to communicate their feelings with their bodies, even in reproduction. Ships of the immigrant fleet generally have "sterile rooms" as delivery rooms or operating rooms, but there are still risks. The most intimate act of the Quelli people is to connect each other's protective clothing. However, doing so will generally lead to the illness of Quelli people, and they will adapt after a period of time.

Like the Turui people, the Queli people are a right-handed protein-based race, which is opposite to humans and Asari people. L-protein food for human beings and Asari is indigestible at best, and toxic at worst, causing strong allergic reaction. If you want to eat something (except those nutritional creams eaten by Kuili people who travel around), you can eat purified and sharp food.
