What are the differences between turtles and turtles?

Turtles have very hard shells and can retract their heads, tails and limbs into their shells when attacked (except sea turtles and snapping turtles). Most are carnivorous and also eat the stems and leaves of plants. The turtle has no teeth, a docile temperament, and patterns on its head and limbs. Soft-shell turtles, commonly known as tortoises and soft-shell turtles, have teeth, can extend their necks very long, and are aggressive. The difference between a turtle and a turtle is that the turtle shell is very hard and has patterns; the turtle shell has no patterns and is mostly dark green, soft and smooth. The head of a turtle is round; the head of a turtle is pointed and its tail is relatively short; turtles only live in fresh water; and there are both freshwater turtles and saltwater turtles. Tortoise is the common name for turtle. In ancient times, the moral standard was "loyalty, filial piety, etiquette, justice, integrity and shame". Literati loved to use contortions to say that people were shameless. Instead of saying it directly, they said "forget the eight" and spread rumors, and they became bastards.
