Bartail Spurdog

About the Bartail Spurdog

The bartail spurdog is a dogfish endemic to Queensland, Australia, at depths of 225 to 455 m.

Like all spurdogs, the bartail has smooth spines on their dorsal fin.

Very little is known about their behaviour or biology since only a few specimens have ever been recorded. The largest one was 62 cm. They’re presumed to be ovoviviparous.

The area they inhabit is not heavily fished, but since nothing is known about this species population trends, they’re considered Least Concern.
