| Abstract |
The low salinity of the Baltic Sea means that marine, fresh water and brackish water crustacean species can inhabit it. Many are benthic organisms. Some remain buried in the bottom sediments, others occur on sandy or muddy bottoms, and some attach themselves to a hard substrate. In the Baltic Sea, the class Malacostraca is represented by six orders. Five of these—Mysidacea, Cumacea, Tanaidacea, Isopoda, and Amphipoda—belong to the Eumalacostraca, while the Eucarida are represented by one order—Decapoda. |
