Additional Creatures Wiki

Eryops are amphibians in Additional Creatures.


Eryops is arguably the largest amphibian on the ARK Network, with a stocky body and a pair of extremely large jaws backed by powerful muscles. While not the fastest creature, its bite and jaw strength is incredible for its size. It utilizes this by burying into soft soil, then facing upwards and unhinging its jaws, before waiting patiently. In this state it hibernates, waiting for vibrations from any unfortunate creature that steps into its mouth. When prey does, Eryops immediately slams shut its jaws like an organic bear trap, and slowly gnawing on prey as they hold it in place. For both its strength and beartrap-like utility, Eryops is valued as a decent all-rounder amphibious mount. yet, when underground, they are highly resistant to narcotic poisons. A clever- or maybe sadistic- survivor found the fastest way to unearth an Eryops without draining it of its stamina or greatly wounding it is to throw a grenade into the poor, unsuspecting creature's mouth! After a moment of panic, the creature will explode to the surface, becoming vulnerable for taming. When tamed, while a good amphibious combat mount with good health, damage, and stamina; they can also be deployed as organic bear traps. If told to chew prey when grabbing, Eryops can work as effective landmines, similar to Purlovia. If told not to inflict damage, they make wonderful taming assistants, immobilizing creatures while their masters deliver narcotic tranqs.

Eryops is immune to venom.

Eryops are capable of burying themselves underground, with only their jaws barely visible. This acts akin to a bear trap, disabling creatures and making them by far the most damaging trap in the game. Eryops are forced above-ground when out of stamina, under 45% hp, or from swallowing a grenade.

In the wild, Eryops cannot be knocked out when underground. If you through a grenade into its mouth, it will swallow it and then promptly combust, forcing it above ground. This allows Eryops to be tranqed.

The damage of Eryops's trap can be toggled, with the no-damage trap using less stamina for the Eryops than the damaging trap.
