Potamon
Introduction '''''Potamon''''' is a genus of freshwater or semiterrestrial crabs mainly found from Southern Europe through the Middle East, and as far east as north-western India. The only exception is the North African ''P. algeriense'', which also is the only potamid of mainland Africa. Twenty species are currently recognised. These crabs are omnivores that have a broad ecological tolerance. The adult Potaman reach up to 50 mm in size during their 10-12 year life span. *''Potamon algeriense'' *''Potamon bileki'' *''Potamon bilobatum'' *''Potamon fluviatile'' *''Potamon gedrosianum'' *''Potamon hueceste'' *''Potamon ibericum'' *''Potamon magnum'' *''Potamon mesopotamicum'' *''Potamon monticola'' *''Potamon pelops'' *''Potamon persicum'' *''Potamon potamios'' *''Potamon rhodium'' *''Potamon ruttneri'' *''Potamon setigerum'' *''Potamon strouhali'' *''Potamon transcaspicum'' *''Potamon ilam'' *''Potamon elbursi'' Many other taxa from Indochina, originally described as species of ''Potamon'', are now placed in other genera, such as ''Himalayapotamon'', ''Beccumon'', ''Eosamon'', and ''Takpotamon''.
