A crab I found on the coast of Islamorada, Florida. I think it might be a European Green Crab, but I’m not positive.

The arrow crab, is a species of marine crab. The body of the arrow crab is triangular, and the rostrum is drawn out into a long point with serrate edges. The legs are also long and thin, up to 10 cm (3.9 in) across, and the animal’s carapace may be up to 6 centimetres (2.4 in) long. Colouration is variable in this species: the body may be golden, yellow or cream, marked with brown, black or iridescent blue lines; the legs are reddish or yellow, and the claws are blue or violet. It is nocturnal and territorial. It eats small feather duster worms and other coral reef invertebrates. They are commonly kept in reef aquariums to control bristle worm population.(Wiki.)

The coconut crab, Birgus latro, is the largest land-living arthropod in the world, and is probably at the upper size limit of terrestrial animals with exoskeletons in today’s atmosphere. The species inhabits the coastal forest regions of many Indo-Pacific islands, are generally nocturnal and remain hidden during the day, emerging only on some nights to forage. The coconut crab is known for its ability to crack coconuts with its strong pincers to eat the contents.
