Crabs are found in oceans. Crabs are not considered water NPCs, instead they walk along the bottom and jump occasionally. Whether or not they're in water has absolutely no effect on their behavior and a player can get them to travel across the entire screen. Crab Statues can be found in caves. When hooked to wire and a switch, pressure plate, etc., it will spawn crabs.
Crabs are very light creatures and suffer from considerable knockback. This can make fighting them annoying, as players have to keep running after them.
