More Info


Distribution

Coral Sea, east of Murray Island, Torres Strait, to off the Gold Coast, Queensland, at depths of 445-508 m. Elsewhere the species occurs off north-eastern Taiwan.

Similar Species

Differs from the similar Halieutopsis galatea in having a subtriangular disk with a pointed rostrum (vs. rounded with a blunt rostrum in H. echinoderma), a broader interorbital space (13.5–16.2% SL, vs. 11.7–12.4 in H. echinoderma), a relatively long pre-anal length (63.1–68.9% SL, vs. 57.4–64.5 in H. echinoderma), and a relatively short tail (31.1–36.9% SL, vs. 35.5–42.6% in H. echinoderma).
H. nasuta, which has a similar vermiculate pattern, differs in having sparse tubercles on the middle of the disk underside, bifurcate (vs. simple in H. echinoderma) principal tubercles on the lateral sides of the tail, in lacking small spines between the principal tubercles (vs. present in H. echinoderma), and a narrower interorbital space is wider (10.3–13.3% SL, vs. 13.5–16.2% SL).

Etymology

The specific name is from the Greek echinoderma (= spiny skin) in reference to the squamation of this species.
