Crabs and crabs do not resemble themselves by chance, but are morphologically and genetically related.

Not all types of cancer have so many obvious similarities to the crabs, as there is a great morphological diversity between these crustaceans. However, they all belong to the same order of the animal world.

If one compares crabs with traditional crabs, which we see, for example, in Spanish dishes, different differences are obvious.

Almost always the crabs are smaller than the cancers. They are between seven and nine centimeters tall. Conventional cancers can easily reach a body length of 12 centimeters.

They also differ in the color of their body. While the crabs have a wide, bluish hexagonal shell, the crabs are usually reddish and their shape is usually rounder.

If we have the opportunity to touch the shell of these crustaceans, we will find another clear difference.

The surface of the shell of the crabs is much smoother and more uniform with velvety areas. Cancers have a rougher and more irregular shell.

Hope I could help you a bit 😉

Cancers are an epitome. Crabs are a group within the cancers.

Is like martens: on the one hand a family of predators (marten-like) – on the other a genus within this family (pine marten, stone marten,…) So all badgers marten(like).

The biological naming often deviates from the naming that we have learned. (peanuts are botanically seen not nuts and bananas are berries).

Crabs have a backed up abdomen, not cancers.

cicindela · Answer

All crabs are cancers or cancers, but not all cancers are crabs. Lobster, shrimp, scampi, hermitic cancers are also cancers. Crabs are crabs with a certain body shape, the headbow is particularly wide and pronounced and the backbow is small and hit under the headbow. And some shrimp species are called crabs.

Cancers are the crustaceans that have a long backing:  Crabs are round.
