The Horsehair Crab is found in underwater in the ocean. Its shadow is medium and it moves in a straight line.
The Horsehair Crab can be donated to the museum. Upon doing so, the following text is given by Blathers:
"Horsehair crabs get their name from their spiky hairs, which can hurt, though they have soft shells. They inhabit the bottom of fairly shallow waters, with their biggest predator being the octopus. They camouflage themselves by putting dirt on their hair so they don't stand out in the sand. Their shells house a tasty portion of innards, so this species is a favorite of those who enjoy crab."
Upon catching the fish, the player will say the following:
"I got a horsehair crab! Because I combed the ocean floor!"
