Summary:

A distinctive coffinfish with a dark greyish to black body, a long tail base (caudal peduncle) and a black lining to the mouth. The Tadpole Coffinfish occurs off Western Australia in depths of 700-1700 m. Coffinfishes use a small shaggy mop-like lure on the front of the head to attract prey. Like shallow-water anglerfishes (family Antennariidae), they usually 'walk' over the bottom on their modified pelvic and pectoral fins.
