The Aquanite is a Slayer monster that requires a Slayer level of 78 to kill and was announced by Jagex in a Guaranteed Content poll on 17 June2009 and subsequently released on 28 July 2009. The poll asked players which name for the new monster they preferred: Aquanite, Gilidrixon, Amphibrath, Lanterwyn, or Anglibian. All of the names were suggested by players on the RuneScape Forums thread "Name A Slayer Creature" in "Suggestions - Monster and NPC". The name Aquanite won the Guaranteed Content Poll over Gilidrixon by 159 votes.
Previously, Kuradal could not assign Aquanites as a task. However, with the Shattered Heart update on 3 March2010, the ability to be assigned Aquanites can be purchased for 50 slayer reward points. Once unlocked, they can be toggled off. Though, in order to toggle them back on, they must be purchased again for 50 slayer points or removed from the assignments list through the use of the cancellation slots.
There is another, faster way for those without 81 Agility. Using a ring of slaying to teleport to Sumona, players run down the Desert Slayer Dungeon into either the Kurask or Turoth rooms, and use the portal, making players have a little walk to their lair. Otherwise, if players do not want to waste points buying/making a ring of slaying, the Bandit Camp's lodestone or the Al-Kharid lodestone will suffice.
Using the Bandit camp lodestone, players will run east to the Desert Slayer Dungeon, or if needed, go down the Smokey Well to avoid unnecessary desert heat damage. If using the Al-Kharid lodestone, stock up at the Shantay pass, and bring either 205-400 coins and head to Pollnivneach.
The examine is a reference to the anglerfish in the movie Finding Nemo.
It has frog-like webbed feet, a bioluminescent light hanging from its forehead like that of an Anglerfish, and a head with whiskers like a catfish; showcasing the real life influence in designing the creature.
In a hidden update in February, Jagex increased the defence of Aquanite because "Too many low-levelled players can kill them very easily".
