Spitting Grapsus grapsus!

Sally Lightfoot Crab,

It is one of the many charismatic species that inhabit the Galápagos Islands, and is often seen in photos of the archipelago.

Notice the 'spitting' from his 'mouth' .... This is actually the crab expelling salt water from his exoskeleton.

 

Seen@Galapagos, Ecuador.
