a turtle has four feet. As a reptile, except snakes have no feet, the others are basically four feet. It should be noted that there are many kinds of turtles, so the shape of the feet is not the same. Terrapins, for example, have webbed feet to help them swim, while tortoises do not. In addition, the turtle's limbs are more like paddles, and the forelimbs are larger.
1. Tortoise shell: The biggest characteristic of the tortoise is that it has a layer of tortoise shell on its body. This layer of shell can play a very good protective effect on it, so that any carnivorous animal can not eat it. Moreover, many turtles can shrink their limbs and heads and tails into their shells, which is more secure.
2. Longevity: As the saying goes, "a thousand years of tortoise, ten thousand years of turtle.". Although the tortoise can not live for such a long time, but the life span is relatively long, the longest life span is the Galapagos tortoise, can live for more than 100 years, and the turtle life span is also very long, the general ornamental tortoise life span of about 15-20 years.
3. Hibernation: Most turtles have the characteristic of hibernation, which allows them to survive the cold winter when food is scarce. Hibernation is generally related to temperature, below 10 degrees Celsius, they will find a suitable place to sleep. Hibernation usually lasts for several months, and when the temperature rises, it will wake up.
