Is the crab a reptile or an arthropod?

Crabs are not reptiles, but crustaceans among arthropods. Crustaceans and reptiles are two different animals, the difference is relatively large, there is no intersection, crabs belonging to crustaceans will not be reptiles. In fact, crabs are quite different from reptiles. Crabs don't have backbones, but reptiles do. Their skeleton composition is also quite different, the main component of crab skeleton is chitin, while the main component of reptile skeleton is calcium carbonate.

Is the crab a reptile

The crab is a kind of aquatic animal that we are quite common, and its distribution is very extensive in all parts of our country.In terms of classification, crabs belong to the arthropod class Crustacea.Therefore, crabs do not belong to reptiles, because reptiles belong to the phylum Chordata Reptilia.In fact, crustaceans and reptiles do not intersect, and the differences between them are relatively large.Therefore, crabs belonging to crustaceans can not belong to reptiles at the same time.

Specifically, the difference between crabs and reptiles is relatively large.Crabs, for example, don't have backbones, but reptiles do, because they belong to the phylum Vertebrata.For example, the composition of their bones is quite different, the composition of crab bones is chitin, and the composition of reptile bones is mainly calcium carbonate.

2. are crabs arthropods

As mentioned above, crabs belong to the phylum Arthropoda, so they also belong to arthropods in terms of category.As an arthropod, the body characteristics of crabs also conform to the general characteristics of arthropods.One of the most important distinguishing features is that the body of arthropods is composed of many segments, and there is an exoskeleton outside the body, which plays an important role in support and protection, and also reduces water loss.The same is true of crabs, which also have exoskeletons that support and protect their bodies.
