Redfinger Rubble Crab

Eriphia gonagra

The Redfinger Rubble Crab is a member of the family Eriphiidae, commonly found in the Western Atlantic Ocean. This species is associated with intertidal sandstone reefs, thriving in shallow waters with a depth range of 0 to 5 meters. Divers are likely to encounter this species in tropical climates, specifically between latitudes 37°N and 31°S and longitudes 100°W and 28°W. As a member of the order Decapoda, the Redfinger Rubble Crab exhibits gonochoric reproductive behavior, meaning individuals are distinctly male or female. Their mating includes a precopulatory courtship ritual, which involves olfactory and tactile cues, and typically results in indirect sperm transfer. Divers encountering the Redfinger Rubble Crab can observe its behavior in the shallow reef areas. The species has not been evaluated for the IUCN Red List, and there is no specific conservation status. As such, divers should appreciate this species as part of the diverse reef ecosystem without concerns about its rarity or conservation threats.
