a turtle has four legs. The body of this animal has a layer of armor, which consists of two parts, one is the bone plate of dermal ossification, the other is the scutum of epidermal keratinization, which can grow year by year. The animal's head and limbs can be shrunk into bone armor to avoid being attacked and eaten by other animals, its limbs are short and thick, with a layer of horn scales, as well as five toes, such as marine fins.
1, long life: As the saying goes, "a thousand years of tortoise, ten thousand years of turtle." Although the tortoise lives less than 10,000 years, but their life expectancy is relatively long, to the Aldabra tortoise, for example, they can live about 150-200 years, the leatherback turtles can live 100 years of time, can be said to be relatively long-lived. Of course, not all turtles can live very long, and some small turtles have a shorter life span.
2. Slow crawling: All turtles crawl very slowly, with the exception of the leopard tortoise, which can reach a speed of 0.28 meters per second, but as soon as possible, it takes 4 seconds to climb about 1 meter, and this speed is three times that of ordinary turtles. But while they climb slowly, they swim much faster, especially turtles, which can reach speeds of up to 29 kilometers per hour in the water.
3. Miscellaneous diet: Except that most tortoises are herbivorous, other tortoises are basically omnivorous, but some prefer meat. Usually fed on small fish, shrimps and fallen melons and fruits, they have a slow metabolism and can not eat for several days after a meal. But also aestivation and hibernation.
