Marine Malacostraca (Arthropoda, Crustacea) from the Gulf of Oran (Algerian west coast)

What is it about?

This present paper presents an update of the inventory of benthic Malacostraca in the Gulf of Oran. The softbottom crustacean fauna was studied between February 2021 and September 2021. Samples were collected from 8 coastal stations. The class Malacostraca was represented with 2 subclasses, Eumalacostraca and Phyllocarida. Sixty-five species and 290 individuals belonging to seven crustacean orders (Amphipoda, Decapoda, Isopoda, Mysida, Tanaidacea, Lophogastrida and Leptostraca) were identified. Amphipoda were represented with the highest number of species (38) followed by Decapoda (14) and Isopoda (6). Tanaidacea and Mysida were poorly represented, with 3 and 2 species, respectively. Lophogastrida and Leptostraca were both represented by only one species. Among the crustacean encountered, Ampelisca was the most dominant genus. The present inventory indicates that the carcinological fauna in the Gulf of Oran is less diversified than it is in other zones that have been studied on the Algerian coast (Gulf of Arzew, Bay of Bou-Ismail, and Bay of Algiers).
