9 species of aquarium crabs

The maintenance and breeding of aquarium fish already bored many aquarists. The fish are replaced by the exotic inhabitants of the seas and oceans – aquarium crabs.

Most often, crabs in nature prefer salt water, but there are also freshwater crabs living in river ecosystems.

Crabs or in other words short-tailed crayfish is a detachment from the Crustacean subtype that are included in the class of Higher Cancers. The remains were found back in the Jurassic fossils. Now they almost did not change their appearance and still resemble their ancestors.

These arthropods are located on almost the entire globe.

Crabs are close relatives of crayfish. Their difference is in the external absence of the abdomen, which ends with the tail part.

They have an abdomen, but it has decreased too much and is located under the breast. The tail would interfere with the movement by land.

In these crustaceans, body size depends on the specific species and ranges from 4 to 35 cm. A distinguishing feature from other animals is the presence of strong claws, which are designed to hunt, protect, and cleanse the body. Another 4 pairs of limbs help arthropods move around.
