The Arrow Crab, (Stenorhynchus seticornis), is a distinctive species recognized for its long, spider-like legs and triangular body. This crab is typically found in the western Atlantic Ocean, ranging from North Carolina to Brazil, and inhabits coral reefs and rocky bottoms at depths of 10 to 30 feet. Its body is usually light tan or whitish, adorned with fine dark lines, while its legs often feature striking orange or red bands. The Arrow Crab is nocturnal, emerging at night to feed on small invertebrates such as shrimp and bristleworms. Its unique appearance and nocturnal nature make it a fun find on any scuba dive.
