Soft-shelled turtles have soft shells with smooth shell surfaces. In some places, they are also called turtles and turtles.

Soft-shelled turtles (soft-shell turtles, soft-shelled turtles, turtles, turtles...) have dark green shells, no patterns, soft, pointed heads, teeth, and long necks. There are land turtles, water turtles, and Amphibious.

Turtle is also called water fish, round fish, soft-shell turtle, foot fish, crawling fish, group fish and tortoise. The turtle's activity pattern can be summarized in four sentences: "In late spring, when the weather is warm, it climbs up the beach, in hot summer, it hides in the shade of willows, in autumn, when the weather is cool, it goes into caves, and when it is cold, it hibernates in the mire.

This is their difference

The tortoise shell is like an oval box, made of hard bone fragments with a bulge in the middle.

The turtle shell is oval in shape and is the leathery skin of the turtle, which is much softer than the tortoise shell. There are some thin ravines in the bulge in the middle of the turtle's shell, and there is a skirt around the shell (☺ The most nutritious part of the turtle's body is the skirt.).

The difference between turtle and turtle:

1. Both turtles and soft-shelled turtles belong to the amphibious and reptile species, the order Turtles and Turtles. One belongs to the family Chelonidae and the other belongs to the family Turtles. They breathe with their lungs and spend most of their time underwater.

2. Soft-shell turtles have teeth and their necks can be stretched very long. Turtles have no teeth and have patterns on their heads and limbs.

3. The limbs, head and tail of the turtle can be retracted into the shell. The limbs of Turtleidae cannot.

4. The turtle's head is round, while the turtle's head is pointed. Its nose is the same as that of a pig, and its tail is shorter.

5. The turtle shell is hard, with lines on the back and a thirteen-petal pattern; the turtle shell is dark green, soft and has no lines, the shell surface is smooth, and the edges are soft.

6. The turtle does not bite, has a docile temperament, and lives in harmony with its companions. If you touch the turtle with something like a branch, it will retract its head. The soft-shelled turtle has a ferocious temperament and will kill each other among its companions. Sometimes it will also attack people or other animals. If you touch a soft-shelled turtle with something like a branch, it will bite the branch tightly and won't let go.

7. Soft-shell turtles live in fresh water, but not turtles.

In fact, animals like turtles and soft-shell turtles are reptiles. Mobile animals are the first vertebrates to truly get rid of their dependence on water and truly conquer land. They can adapt to various different land living environments. Reptiles are also the animals that have dominated land for the longest time.

Can you tell which of the following animals are reptiles? Think carefully about what other common reptiles are in our lives?
