Summary:

This large deep-bodied boarfish has long, stubby 'whisker-like' villi on the chin, five dark bands on the body, and yellow dorsal, anal and caudal fins. Striped Boarfish occur at Lord Howe Island region and Norfolk Island in the Tasman Sea, where pairs are sometimes seen around deeper drop-offs, overhangs and nearby sandy areas.

More Info


Distribution

Known in Australia's maritime waters, from Lord Howe Island and Norfolk Island in the Tasman Sea. Elsewhere the species occurs in the Western-Central Pacific: New Zealand, Japan, Hawaii and Easter Island.

Inhabits coral and rocky reefs, often in pairs, usually deeper reefs, deep rocky drop-offs and nearby sandy areas in depths of 10–180 m.

Features

Dorsal fin IV-V, 26-28; Anal fin III-IV, 11-14; Vertebrae 27.

Body very deep, broadly rounded below dorsal-fin rays, snout slightly elongate, robust in adults, lips and chin with dense ‘whisker-like’ villi, those on chin very long and sometimes divided; dorsal fin tall, sail-like with a convex posterior margin; dorsal spines stout, progressively increasing in length; anteriormost dorsal-fin rays much longer than posteriormost fin spine.

Size

To 90 cm in length.

Feeding

Carnivore - reportedly feeds on brittle stars at night in Hawaii.

Similar Species

Differs from the similar Histiopterus typus in having a deeper, striped body, and short dorsal and anal-fin spines (vs. third and fourth dorsal, and third anal-fin spines elongate in Histiopterus).
