Summary:
A short rounded ceratioid anglerfish with extremely long dorsal- and anal-fin rays enveloping the body, and a long illicium on the snout tipped with whitish bioluminescent esca (lure) having a tuft of many filaments. The whisker-like filaments and fin rays are bioluminescent and may act as a net. The smaller males are parasitic on the females.
Fabulous footage of a female Fanfin Angler with a dwarf male fused to her belly.
The pair were filmed by a deep-sea submersible at a dpeth of 800 metres off São Jorge Island, the Azores, Portugal, August 2016.

Distribution

Off Newcastle, New South Wales, to south of Tasmania, and on the Norfolk Ridge in the Tasman Sea, just south of AUS EEZ (32º37´S, 167º47´E). Elsewhere the species is circumglobal in all oceans, except Polar seas.

Features

Dorsal fin 16-19; Anal fin 14-18; Pectoral fin 16-19; Upper jaw teeth 17-39; Lower jaw teeth 12-26; Vomerine teeth 2-5.
Illicium pigmented except near esca, with 5-14 elongate translucent filaments along entire length, all but distal-most arising from posterior margin; length of illicium 16.8-36.8%SL; stem of illicium pigmented except near esca; esca with an elongate filamentous anterolateral appendage; 2 distal appendages, each bearing numerous filaments, anterior most short and stout, opaque along posterior margin, posterior most considerably more slender; posterolateral appendage bearing numerous short filaments and with palmate opaque distal tip.

Biology

The smaller males are parasitic on the females. Larvae and free-swimming males have pelvic fins, which are lost in females and parasitic males. Males grow to about 1.6 cm TL.

Etymology

The species is named for American ichthyologist, David Starr Jordan.
