Akhlut (5e Creature)
From D&D Wiki
Large monstrosity, unaligned
Swallow. The akhlut makes one bite attack against a Medium or smaller target. If the attack hits, the target is swallowed. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the akhlut, and it takes 5 (2d4) acid damage at the start of each of the akhlut's turns. The akhlut can have only one target swallowed at a time.
The akhlut is a vicious predator which stalks land and water. It has the muscular legs of a wolf and the body and head of a killer orca. These qualities combined give it speed on land and deadly chasing ability in the waters, where it often hunts prey other than fish.
