The Leech, an aquatic, herbivore creature in ARK: Survival Ascended, is a notable presence across multiple maps.

Its base Stamina of 100 gives it tires quickly. Dealing 100% base Melee Damage, the Leech brings decent hitting power to the table. The Leech has 40 base Health - extremely fragile. A base Weight of 10 means minimal inventory space.

The Leech cannot be tamed and must be dealt with through combat or avoidance. Defeating one in the wild grants 1 base XP. It can be cloned at a Cloning Chamber for 100 Element plus 5 Element per level.
