It is endemic to northeastern Australia, found on the upper continental slope off Queensland from south of the Samaurez Reef, at a depth of 246–405 meters (807–1,329 ft).

Its specific epithet delicatus is Latin for "delicate", referring to the fine teeth on its saw-like rostrum.

The elongated, saw-like snout tapers evenly to its tip, and bears very slender lateral teeth of variable length and a pair of filamentous, dorsoventrally flattened barbels.

[4] The mouth is large and broadly arched; there are 47 tooth rows in the upper jaw and 37 in the lower.

The pectoral fins are large with narrowed rounded tips and weakly concave rear margins.
