Dorsale stekels (totaal): 2; Dorsale zachte stralen (totaal): 0; Anale stekels 0; Anale zachte stralen: 0. Conspicuous black tips on dorsal fins, black dorsal caudal margin, black ventral caudal lobe (Ref. 247).
Found on the insular slopes (Ref. 247). Feeds on lanternfishes, boarfishes, barracudinas, and flatheads (Ref. 247). Probably ovoviviparous (Ref. 247). Defends themselves from their captors by whipping their bodies and long second dorsal spines (Ref. 247).
