Abstract

In the present study, the most recent visceral crustacean Potamon magnum was studied. It is a genus of freshwater or semi-earth crabs found mainly through the Middle East from Southern Europe, as far east as north-west Egypt. The mere exception is the North African P. algeriense, which is also continental Africa's only potamid. There are currently 20 species identified. Such crabs are omnivores with high environmental tolerance. Throughout their 10–12 year life span, the adult Potamon spp. reaches up to 50 mm throughout length. Some crustaceans are aquatic animals that are free-living, but some are terrestrial (for example, woodlice), some are parasitic (for example, rhizocephala, fish lice, tongue worms) and others are sessile (for example, barnacles). The group has an extensive record of fossils, reaching back to the Cambrian, and includes living fossils such as Triops cancriformis, which since the Triassic period seemed unchanged. More than 7.9 million tons of crustaceans—mostly shrimps and prawns—are produced annually for human consumption by fishing or farming. Krill and copepods are not as widely fished as they are, but they may be the animals with the greatest biomass on the planet, forming a vital part of the food chain.
