Among the Caridea include more than 2,500 of the 3,000 shrimp designated crustaceans . They are mostly small crustaceans with a cylindrical carapace . Most Caridea species live in the sea, including in coral reefs and in the deep sea , but there are also freshwater species (e.g. freshwater shrimp (Atyidae)).
features
The first two pairs of legs are with or without scissors. The third pair of legs is always without scissors. The second segment of the abdomen is laterally widened and protrudes over the rear edge of the first and the front edge of the third abdominal segment . The gills consist of a central shaft with round branches. As in all pleocyemata, the females carry the eggs with them on their abdomen until the protozoal larvae hatch .

use
fishing
A few Caridea species are caught commercially (e.g. the North Sea shrimp ( Crangon crangon )) or propagated in shrimp farms (e.g. Macrobrachium rosenbergii , Fam. Palaemonidae) and are sought-after delicacies . Most of the edible "shrimp" belong to the Penaeoidea and not to the Caridea.
Aquarium keeping
Some freshwater shrimp and rock shrimp are also kept in freshwater aquariums, e.g. B. the Japanese freshwater shrimp , which is popular as an algae fighter. Crabs , cleaner and marble shrimp , rock and partner shrimp , harlequin shrimp and dance shrimp are kept in seawater aquariums . The claw shrimp, which are also kept in saltwater aquariums, do not belong to the Caridea.
