Barbourisidae Parr, 1945 (lapsus) |
The velvet whalefish, Barbourisia rufa, is a deep-sea whalefish, the sole member of its family Barbourisiidae. It is found throughout the tropical and temperate parts of the world's oceans, mainly in the Pacific near Japan and New Zealand, at depths of 300 to 2,000 m. This species seems very closely related to some flabby whalefishes and it was initially believed to belong into that family by some (e.g. Myers 1946).
Like other whalefishes, it has a generally whale-shaped body, small pectoral and pelvic fins, and dorsal and anal fins set far back. Body and fins are covered with tiny spicules, resulting in a velvety feel that inspires the name. Color is an overall vivid geranium red or dark orange. The mouth is large, extending well behind the eyes, has a white interior, and the lower jaw projects beyond the upper jaw. The largest recorded specimen was 34.5 cm; another fairly large specimen weighed 456 grams.
Little is known of their habits, but they are believed to feed on crustaceans.
