horseshoe crab

The horseshoe crab's bizarre body shape is undoubtedly its most striking feature. Due in large part to their extremely long and thin, spiky tails, many have come to view horseshoe crabs as intimidating creatures. This misconception stems from the presence of these sharp protrusions, which often spark fear. In actuality, however, these crustaceans pose no real threat to humans. Instead, they use this impressive appendage to quickly right themselves whenever overturned by accident.
