Sally Lightfoot Crab

Grapsus grapsus

MEDIUM
Family
Grapsidae
Also known as
Red Rock Crab, Abuete Negro, Lightfoot Crab
Description
Sally Lightfoot Crabs are highly agile, brightly colored shore crabs found along rocky coastlines. Juveniles are dark brown to black, while adults display vivid orange-red to yellow coloration with dark patterning on the carapace. They are omnivorous scavengers, feeding on algae, detritus, dead fish, and other organic material.
Habitat
Rocky intertidal and supratidal zones along exposed coastlines; found throughout the eastern Pacific from Baja California to Chile, and commonly associated with the Galápagos Islands; typically found from the splash zone down to shallow subtidal areas.
Conservation status
Least Concern
Notes
This is not an underwater photograph — the crab is photographed out of water on a rocky shore, likely an intertidal or coastal environment. The orange-yellow coloration with dark brown mottling on the carapace is consistent with a sub-adult or adult Grapsus grapsus. Some ambiguity exists as other Grapsus species share similar coloration. Dried plant debris and small green algae patches are visible on the rocks.
