Spinolyps are small, Dagannoth-like creatures found in the deepest sublevel of Waterbirth Island Dungeon. They are not often killed as they attack with both magic and ranged, causing players to switch prayers often. Their ranged attacks can also cause poison, which starts at 68 life points. They mainly serve as a nuisance, similar to Wild dogs in the Brimhaven Dungeon.
There used to be a glitch where equipping an Anti-poison totem would not prevent a Spinolyp's ranged attack from causing poison, even if the player wielding it was unpoisoned.
Spinolyps will turn into level 34 Suspicious water when dealt enough damage. If the water gets close to you, it will deal a rapid, inaccurate melee attack.
It isn't recommended to use protection prayers against Spinolyps the whole time because doing so will consume a large amount of Prayer potions and a bank is quite a big distance away, instead its advised to bring your best armour against Ranged attacks, as the magic attacks are less accurate than the ranged. Bringing a Spectral spirit shield is very useful as it has a very high mage and ranged defence bonus.
In September 2010, in the lair that Spinolyps are located along with the Dagannoth Kings, Spinolyps did not attack or were unable but still looked at the player, as if they were.
