What is "potamon"

Potamon, in Greek mythology, is one of the sons of Aegyptus and Caliadne. He married (and was murdered by) Glaucippe, one of the Danaids, daughter of Danaus and Polyxo.

Potamon is a genus of freshwater or semi-terrestrial 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:

• Potamon algeriense Bott, 1967
• Potamon bileki Pretzmann, 1971
• Potamon bilobatum Brandis, Storch & Türkay, 2000
