Rock Crab


 * Not to be confused with Granite crabs and the Giant Rock Crabs.



your mon  are aggressive monsters that look like harmless rocks while they are sleeping but that wake up and attack unsuspecting passers-by; however, once their target leaves the nearby area, they are no longer aggressive. These monsters are quite popular for training, especially on lower-levelled players, because of their very high life points relative to their low combat level. Unlike most monsters, rock crabs are able to stand on each other in the same spot (making them good targets for area-attack spells such as Ancient Magicks spells and the Dragon 2H special attack). Additionally, rock crabs are a good source of gold charms for lower-levelled players. Most rock crabs are located in multi-combat areas, making them good targets for cannons, especially as their low combat level allows for more consistently higher hits.

The issue with rock crabs that makes them not as desirable for higher-leveld players is that while rock crabs have high life points whene compared to their combat level, they still have too few life points to create an effectively lengthy period of combat once one is able to hit reasonably consistently over 100-150 life points.

It should be noted that, unlike other enemies and NPCs, rock crabs are not marked with yellow dots on the minimap; this is probably due to the fact that the crabs' appearance camouflages them as rocks.

It should also be noted that, as with most aggressive monsters, rock crabs will stop attacking a player if they have not left the surrounding area in a considerable amount of time (roughly between ten and twenty-five minutes); as they are "dormant" until "awoken" by a passing player, rock crabs cannot be attacked until they are made aggressive once more. To fix this, simply run out of the surrounding area (to be sure, run halfway to the entrance to the village of Rellekka) and run back, at which point the rock crabs will once more be aggressive.

In the quest Fur 'n' Seek, its carcass must be collected and cleaned for the Odd Old Man.

For extremely low defence leveled players, it is recomended that if you are killing these creatures for long periods of time, you bring some food just in case as there are no nearby banks.

Classification
These animals are most likely, as the name suggests, a form of crab, noting that the rock crabs always walk sideways (and attack using their side legs as well). It is possible that they may belong to a different animal phylum, such as insects, and only look like crabs, although this is not very likely. The animals are always spotted near water; while the graphics of RuneScape do not show them immersing themselves in water, it can be safely assumed that they would hypothetically do so. In the quest Fur n' Seek, the rock crab's carcass that is collected by the player consists of only a shell and other, not easily visible remnants.

Trivia

 * When rock crabs are camouflaged, if you look at them closely, you can see some of their legs showing.


 * The examine option for the crab when it is camouflaged is different when it is active.
 * You can notice the "living" rocks by right-clicking the rocks. If they're crabs it is marked as yellow, when the normal rock would be blue.
 * The examine for rock crabs is:"No-one likes crabs." This could be a reference to the parasite.
