Thaumatichthys pagidostomus
Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Lophiiformes
Family: Thaumatichthyidae

Thaumatichthyidae, the wolftrap anglers, is a small family of deep-sea anglerfishes, containing two genera and eight species found in all oceans. They are commonly known as wonderfish (a literal translation of Thaumatichthys), or wolftrap anglers or wolftrap seadevils because of their distinctive upper jaws with movable premaxillaries that can be lowered to form a cage-like trap around the much shorter lower jaw. They are related to (and were formerly placed within) the family Oneirodidae.[1]
