Aesthetic Identification: The Ornate dogfish has a somewhat compressed, stout, blackish body and fins without any conspicuous markings. The first dorsal fin is low and rounded with a very elongated spine nearly as high as the second dorsal fin spine which reaches above the fin apex. The second dorsal fin is larger, with very long spine extending above the fin apex. There is no anal fin.

Biology and Reproduction: Unknown. Presumably ovoviviparous.

Behavioral Traits, Sensing and Intelligence: Unknown.

Ornate Dogfish Future and Conservation: The Ornate dogfish is rare and there isn’t enough data to evaluate. They are not of interest to fisheries.

Ornate Dogfish Recorded Attacks on Humans: Not a threat to humans.
