Giant crabs are non-intelligent monsters found in shallow waters, coastal rivers, and buried in sand on beaches. They cannot swim. The common giant crab is 8' in diameter, but larger specimens may be found. Both salt- and fresh-water species exist. They are always hungry and will attack and eat anything that moves.2


Giant crabs are straightforward combatants, surging forward and attacking with their claws. They typically fight until slain.

Improved Grab (Ex): To use this ability, a giant crab must hit with its claw attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold, dealing automatic claw damage each round until its opponent is freed or dead.

The giant crab first appeared in the Dungeons & Dragons Expert Rulebook, by Gary Gygax and Dave Arneson (1983).
