Additional Creatures Wiki

Ophthalmosaurus is a reptile in Additional Creatures.


A large, primarily open-ocean swimming ichthyosaur. A deep diver, it spends its time hunting in the abyss in the safety of its companions. Adapted for life in the deep, its large eyes make it an incredibly efficient deep-sea hunter as it hunts soft-bodied prey primarily. Comparable to modern orcas, they have a similar bond with each other as a pod and will fiercely protect each other and attack anything that threatens them or they think they can eat. Tamed, they prove effective deep-sea mounts and decent fighters, their strength growing in groups
