Tell me about the difference between a tortoise and a tortoise.

Turtles belong to Tortoise, and turtles (tortoises) belong to Tortoise, different families and different species. Although turtles and tortoises look the same in appearance, they both have tails, limbs, shells, and especially heads. But the biggest difference between the two is that the tortoise has a hard shell, like a shield, with a big nail on it. The turtle shell is smooth and softer than the turtle shell, and looks like a lump of wormwood from a distance. Both species are omnivores, but turtles are much more fierce than turtles. The other two are hibernating.
