Why does the tortoise crawl so slowly?

The reason why turtles crawl slowly: the shell of turtles is their exoskeleton, and the shell wraps their legs, making them unable to move flexibly, which is also one of the important reasons. Many turtles live in water, and their body structure is more suitable for swimming in water than walking on land.

The hard exoskeleton can protect the tortoise from injury when it is in danger. If rabbits escape predators by running; Then the tortoise and the hedgehog just surround themselves and let the hard turtle shell or sharp thorns protect themselves. Such a survival strategy does not require the tortoise to light up the "running" skill at all.

In fact, turtles can run! It's just that they can't run fast or far. The tortoise has only one ventricle, so it can't run continuously, or the heart attack will not pay off.

Extended data:

The tortoise's skeleton is specialized to form a turtle shell, and the trunk bone has been consolidated into a whole, so the waist can't drive the limbs to move, and it loses some flexibility. Moreover, the muscles of the limbs are underdeveloped and only rely on limited movement of the limbs, so the speed of progress is relatively slow.

The shell of turtles is their exoskeleton, and the density and weight of bones will account for a large part of most animals. Therefore, it is beneficial to have water to reduce the weight when the turtle is in the water. Once they reach the land, the gravity generated by this weight is not suitable for them and will naturally slow down.
