Are turtle, turtle, tortoise and tortoise the same? Does it mean the same animal? What is the difference between the four?

Soft-shelled turtles, soft-shelled turtles, turtles and bastards are the names of animals that are often mentioned in our lives, but many people don't know, are they the same? Does it mean the same animal? What's the difference between the four?

Soft-shelled turtle, also known as soft-shelled turtle, water fish, round fish, foot fish, crawling fish, ball fish. So, soft-shelled turtle refers to the soft-shelled turtle.

"son of a bitch" is more complicated.

Its original meaning is "a man who indulges his wife to have an affair". At that time, it was written as "forget eight".

Later, people use "duck" to refer to or compare "son of a bitch", because of the Chinese breed in the past, the duck's head is green. (see Water margin)

Later, I also referred to "tortoise". See ("Red House", Xue Xun: "marrying a man is a tortoise" and "husband is a son of a bitch").

Now it is basically used as a nickname for "soft-shelled turtle" all over the country.

In the Chinese textbooks published in Korea during the Ming Dynasty, there is already a saying that "son of a bitch" refers to "soft-shelled turtle", but its "king" is written as "Zuoyue right king" and "eight" as "bully".

So now we just need to compare the difference between turtles and turtles.

What the two have in common:

1. Reptiles

2. Breathe through the lungs

3. Oviparity

4. In vivo fertilization

5. Variable temperature animals

6. Reproduce on land

The differences between the two:

1. The limbs, head and tail of turtles can be retracted into the shell, but the limbs of turtles cannot.

2. There are lines on the back of the tortoise, patterns on the head and limbs, but not on the turtle.

3. The tortoise's head is round and the turtle's head is pointed

4. The shell of the turtle is hard, the shell surface of the turtle is smooth, the edge is soft, and the nose is the same as the pig's nose.

5. The belly of the turtle is grayish black, while the belly of the turtle is white or slightly red

6. Turtles have a hard beak and no teeth. Most of them are gentle and do not take the initiative to attack other animals. Soft-shelled turtles have teeth and are ferocious. They often attack other animals only when they think they will be in danger.
