Sally Light-foot crabs are very frequent on almost every rocky shore of the Galapagos Islands. Nimble-footed and photogenic, these crabs are excellent models, though they may be a bit shy for close-ups, scurrying away sideways, up slopes or hiding in between rock crevices. These colorful crabs surely stand out against the dark-colored lava. Occasionally, you may see a crab "spitting" from near its eye. Actually, the stream of liquid is the Sally Light-foot crab's way of expelling saltwater that seeps into its exoskeleton.
