FamilyInachidaeAlso known asSpider Crab, Yellowline Arrow CrabDescriptionThe arrow crab is a distinctive spider crab characterized by its extremely long, spindly legs and triangular, arrow-shaped body. It feeds on bristle worms, small invertebrates, and organic detritus on the reef. Its reddish-brown coloration with fine striping along the carapace and legs makes it unmistakable among Caribbean reef invertebrates.HabitatFound throughout the Caribbean Sea and tropical western Atlantic, typically sheltering in crevices, under coral ledges, and around sponges at depths from 1 to 200 meters. Common on coral reefs and rocky substrates.Conservation statusLeast ConcernNotesVery clear image with good lighting. The crab is positioned at the base of a large encrusting sponge on a sandy substrate. Long legs are fully visible and spread wide, making identification straightforward. A small cleaner shrimp (possibly Ancylomenes pedersoni, indicated by the blue coloration near the claws) appears to be present near the crab's chelipeds.Creatures detected4 in frame- Arrow Crabinvertebrate
