Acartia
Acartia is a genus of marine calanoid copepods comprising the majority of species in the family Acartiidae. They are small, planktonic crustaceans found primarily in temperate coastal and estuarine waters worldwide. The genus includes ecologically important species such as A. tonsa, which is among the most abundant and well-studied estuarine copepods globally. Acartia species serve as key intermediaries in aquatic food webs and are increasingly used as model organisms for studying coastal plankton dynamics, thermal ecology, and phylogeographic patterns.
