Sally Lightfoot Crabs of the Galapagos Islands

Ok, maybe the below is a bit of an irreverent depiction of these snazzy, colorful crustaceans, but sitting at a computer most days for many hours of the day makes me a bit snippy at times; gotta have a little fun every now and then 🙂

And these guys and gals were a bit snippy, scuttling away as I tried to take photos, clawing all over while flailing up, down and around the rocks.

Then a wave would hit, and they wash off and wash back up drenched in frothy sea foam and I wouldn’t get a shot. The nerve. I call that a bit snippy.

What’s a Sally Lightfoot Crab?

Their formal names are ‘Grapsus grapsus’ and ‘Percnon gibbesi’. The version (species) found in South America is Grapsus grapsus. A common name is ‘red rock crab’ and that makes sense. The ones we saw were beautiful shades of dark orange and reddish in color, some with a touch of baby blue.

Sally Lightfoot Crabs are semiterrestial, meaning “living mostly on land but requiring a moist environment or nearby water, especially as a breeding site. Most amphibians are semiterrestrial”.   Source:

They are found in many areas of the Galapagos Islands. All the shots I have included here are from an evening excursion to Floreana Island during our time on the good ship cruise ship M/V Santa Cruz.

You can see Sally Lightfoot Crabs and get some photographs during a beach trip to Garrapatero Beach also.

Garrapatero Beach is on Santa Cruz Island, near the Cerro Mesa Ecological Reserve; make sure to visit and spend time enjoying watching the Giant Galapagos Turtles.
