Description: The arrow crab is a visually striking marine species found in the warm waters of the Atlantic Ocean, particularly the Caribbean Sea and Gulf of Mexico. Its elongated, arrow-shaped body features vibrant colors, ranging from deep reds to bright yellows. Arrow crabs inhabit coral reefs and rocky substrates, showcasing adept climbing abilities with their sharp legs.
