The tortoises living in the wild environment, although they have hard tortoise shells to protect themselves, they are not completely unable to meet animals that want to eat them, so in order to be on the safe side, they must observe the movement around them, because the tortoises themselves are not high, if they want to get a broader field of vision, the best way is to stack them like a pyramid. Only when the stack is so high can we see far and find the enemies around us more easily.
Many turtles live in the water, rarely come to the shore, sometimes stay in the shallows, but because the space is relatively small, it may not be able to accommodate more turtles, so that other turtles will climb up, so that they can bask in the back. Usually the smaller ones are on top and the bigger ones are on the bottom.
Tortoise pyramid is also a risk-avoiding mechanism, because it mainly depends on the vibration around it to judge whether there is an enemy. When multiple turtles are stacked together, the feeling will be more obvious. In this way, it is convenient for them to quickly escape into the water, and it is also convenient for them to pass information to other turtles.
Domestic turtles do not need to avoid danger, and the drying table is very spacious, but they still have the habit of piling up, so this is also the habits of species, which is difficult to change through artificial domestication.
