The Morsvectoridae is a small family of hadalpelagic amphibians from the Cold King's Trench.
The most famous, and largest, member of the family is the Grim Walker (Morsmessor crepusculi).
A very cryptic family of amphibians, little is known on their behavior and life.
The family is characterized by the peculiar locomotory system they evolved to walk on the ocean floor and the loss of an active swimming life style.
