Caridea
Caridea
Caridea (pronunciation: /kəˈraɪdiə/), also known as shrimps or true shrimps, are a taxonomic group in the order Decapoda of the class Crustacea. The term "Caridea" is derived from the Greek words "kari" meaning "nut" and "eidos" meaning "form", referring to the hard shell of these creatures.
Description
Caridea are small to medium-sized marine animals, typically characterized by a compressed body, a flexible abdomen, and a hard exoskeleton. They have five pairs of legs, the first three of which are equipped with claws, known as chelae. The body of a Caridea is divided into two main parts: the cephalothorax (head and thorax combined) and the abdomen.
Distribution and Habitat
Caridea are found worldwide, in both freshwater and marine environments, from the deep sea to shallow ponds. They are particularly abundant in the tropics but can be found in all types of aquatic habitats.
Diet
Caridea are omnivorous, feeding on a variety of organic material, including plankton, detritus, and small organisms. Some species are also known to be scavengers or predators.
Reproduction
Reproduction in Caridea involves the female carrying the fertilized eggs, which are attached to her swimmerets, until they hatch into free-swimming larvae.
