Anonymous users2024-02-12Crabs are not amphibians, it belongs to the class Crustacea of the phylum Arthropods. The concept of amphibians does not refer to animals that can live both in water and on land, but rather animals with limbs that can walk and jump on land and swim in water.
Crabs usually live in water, especially in the ocean or in shallow areas along the coast. They usually mate in the water, and the resulting young crabs also grow in the water until they are mature enough to migrate to land. Although crabs can live both in the water and on land, their main living environment is still in the water.

Anonymous users2024-02-07Do crabs swim in water or on land? Let me tell you this, crabs spend a lot of their time in the water. What is rarely seen on land, if it is on the beach, then it is also on the seaside.
A beach with water can only be infested normally. It's slower to get to land. Therefore, he belongs to the water swimming.

Anonymous users2024-02-04No. The so-called amphibious means that juveniles can only live in water, not on land. Adults can live in the water as well as on land.
Whereas, crabs are crustaceans.
If you want to ask why some crabs live in the water and some live on the ground.
Then I just want to say that it is the result of the long-term evolution of different breeds. It's like a tortoise, you throw a tortoise into the water and drown.
To use another analogy, it's like a man and a monkey, one lives on the ground and the other lives on a tree. Anyway, in the eyes of crabs, monkeys and people are the same. But ......The varieties are different wow
