Arrow Crab

Stenorhynchus lanceolatus

The Arrow Crab, known scientifically as Stenorhynchus lanceolatus, is a species of crustacean that inhabits tropical benthic environments. It is primarily found in the Eastern Central Atlantic, with its range extending from Madeira and the Canary Islands down to Angola. This species is often associated with rocky reefs and is known to inhabit shallow waters, as 93% of recorded observations occur at depths shallower than 40 meters. The Arrow Crab is recognized for its unique, elongated body and long, slender legs, which give it a distinctive arrow-like appearance. This physical trait helps differentiate it from other crustaceans in its habitat. Divers encountering the Arrow Crab may find it perched among rocks or other structures on the sea bed. It is harmless to humans and does not have any known threats or conservation concerns, as it has not been evaluated by the IUCN Red List. Observing this species can provide insight into the diverse marine life present in its distribution range.
