Breasted turtle (definite introduction)
Black turtles are quiet animals, so we usually rarely Seeing that they have such a strong communication, we usually rarely pay attention to them. It is precisely because of this reason that it is difficult for us to observe what special functions the various organs of pet turtles have. So let’s talk about the important organs and functions of pet turtles here.
1. Skin
The biggest characteristic of turtle skin (except the front end of the head) is that it is rough. The epidermis has fine granular or small scales, which protect the dermis, Reduce friction with the outside world and reduce the evaporation efficiency of body water.
2. Nose
There are two nostrils on the glans penis, but there is only one nasal cavity. The bones in the nostrils are covered with epithelial mucosa and have sensory functions. Among them, the pirinasal organ is their important sensory organ. Because when turtles are looking for food or crawling, they often stretch their heads and necks very long to feel for breath and then decide where to move.
3. Eyes
The structure of the turtle's eyes is very typical. The cornea is convex, the lens is rounder, and the ciliary muscle is developed. The curvature of the lens can be adjusted to adjust the visual distance, because , Turtles generally have a wide field of vision, but poor clarity. Therefore, turtles are more agile when it comes to moving objects, but react clumsily to still life objects. According to surveys by British zoologists, most turtles can have different colors like humans, especially reacting more quickly to red and white.
4. Ears
The hearing organs of turtles are only the ear and middle ear, not the outer ear. And the outermost surface is a saturated film. Therefore, turtles are clumsy about airborne sounds. It is more sensitive to the oscillations conducted by the earth. Therefore, generally speaking, turtles are simply regarded as both dumb and deaf animals.
