Two nice and colorful Sally Lightfoot crabs (Grapsus grapsus) from the rocks along the coast of Lima in Perù. Looking forward to visit Peru once again in the future years! I know #coronavirus is doing a mess there too and I send a home-hug to all my Peruvian friends and colleagues. Stay home, stay safe! #pickoftheday #peru #lima #crab #crustacean #grapsus #sealife #sea #rocklife #portrait @ilcp_photographers @conservacionamazonica https://www.instagram.com/p/B-H5KnGqodr/?igshid=172u31mmvr1t7

Sally Lightfoot Crab - Grapsus grapsus  

Grapsus grapsus (Decapoda - Grapsidae) is a little studied species despite their wide geographic distribution ranging from Baja California in Mexico to Talcahuano in Chile, including the Galapagos and Juan Fernandez islands.

The Sally Lightfoot Crab, as it is commonly known, is a common, semi-terrestrial crab; it is carnivorous, feeding on barnacles, mussels, porcellanid crabs and other invertebrates; occasionally it is also scavenger. Despite being such a conspicuous species in rocky shore communities, their population ecology and their role in these communities are unknown.

In G. grapsus from the Galapagos has been observed the model of courtship called "search - intercept", in which males hold temporal areas for courtship and copulation, and intercept the females, which may or may not accept copulation.

In field observations on copulation of these crabs, has been corroborated the occasional occurrence of harassment of males to females, aggressive behavior between males, autotomy and cannibalism.

Sally Lightfoot Crab (Grapsus Grapsus)

Sally Lightfoots are very common, and you can get fairly close before they scuttle in to a crevice in the rocks. These creepy chappies run around on the tips of their toes, scuttling along the volcanic rocks of the Galapagos, providing a stunning contrast to the black background. Their main diet is algae, but they will also eat plants and scavenge on dead animals, including other Sally Lightfoot crabs.
