Containing group: Lophiiformes


The Lophichthyidae is a poorly known, monotypic family of lophiiform fishes restricted to the western central Pacific. The only known species, Lophichthys boschmai Boeseman, 1964, apparently does not exceed 75 mm total length. Nothing is known about this species' biology or habitat; however, it presumably lives a life similar to other shallow-water anglerfishes, which despite their sedentary nature, are voracious carnivores that sit quietly waiting for smaller fishes to pass by, at which time they enticingly wriggle their esca to attract potential prey to their mouths. Although occasionally caught in commercial bottom trawls, lophichthyids are of no significant economic interest.


Body elongate, compressed. Mouth large, opening oblique to vertical, lower lip without small, cutaneous appendages. Jaws with one or two rows of small, recurved teeth. Eyes small, dorsolateral in position. Opercular opening restricted to a small pore located at the end of a shore tube, behind and above pectoral-fin base. Spinous dorsal fin with three slender spines, widely separated from each other and from soft part of dorsal fin. First dorsal-fin spine modified as an illicium with a well-developed esca; the second and third spines free, not enveloped by thick skin. Pectoral-fin lobe elongate, leg-like; pectoral-fin single, not divided into upper and lower portions. Skin with numerous, small cutaneous appendages; skin of dorsal and lateral surfaces of head and body spinulose (Pietsch, 1981).

Color in preservation white on belly to light pink on the lateral and dorsal surfaces of head and body, with slightly darker brown reticulate pattern on upper part of body; membranes of fins (except those of the caudal fin) dark brown, with closely spaced white spots; oral cavity and viscera unpigmented (Pietsch, 1981).

The hypothesized relationships of the Antennarioidei as presented by Pietsch (1981) and Pietsch and Grobecker (1987). See below for character states.

The family Brachionichthyidae is classified as the basal sister taxon of a clade including the Lophichthyidae, Tetrabrachiidae, and Antennariidae; these four families forming the lophiiform suborder Antennarioidei (Pietsch, 1981; Pietsch and Grobecker, 1987). Monophyly of the suborder and the relationships within it are supported by a total of seven synapomorphies (see above cladogram):

  1. Posteromedial process of vomer emerging from ventral surface as a laterally compressed, keel-like structure, its ventral margin (as seen in lateral view) strongly convex;
  2. Postmaxillary process of premaxilla spatulate;
  3. Opercle similarly reduced in size;
  4. Ectopterygoid triradiate, a dorsal process overlapping the medial surface of metapterygoid;
  5. Proximal end of hypobranchials II and III deeply bifurcate;
  6. Interhyal with a medial, posterolaterally directed process that makes contact with the respective preopercle;
  7. Illicial pterygiophore and pterygiophore of third dorsal-fin spine with highly compressed, blade-like dorsal expansions.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
