Hermit crabs are aggressive monsters that look like harmless shells while disguised, but attack when walked by. Unlike most other enemies and NPCs, hermit crabs are not marked with yellow dots on the player's minimap; this is probably due to the crabs' appearance, which camouflages them as shells.

Players can tell if a shell is a hermit crab by right clicking on them. If the text colour is yellow, it is a hermit crab. If the text is blue, it is just scenery.

Hermit crabs are excellent for training at low-mid combat levels due to their low Defence and relatively high Hitpoints, though low level players should consider bringing food. They may also be useful as a passive way to gain Iron cannonballs as well as the various frags needed for coral farming.

Hermit crabs do not count towards a crab slayer task.

Like all other crabs, hermit crabs start off aggressive but will become tolerant of the player after ten minutes. As they must be active in order to be fought, players must reset their aggression timer once they become tolerant. To make the crabs aggressive again, exit the surrounding area and enter again. As they are "dormant" until "awoken" by a passing player, hermit crabs cannot be attacked until they are made aggressive once more.

Drop rates are estimated based on 13,900 samples from the Drop Rate Project, unless otherwise cited.
