Etymology: Halaelurus: halos (Gr.), sea; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes (See ETYFish); maculosus: Latin for speckled, referring to speckling of small dark spots over dorsal and lateral surfaces of body (See ETYFish).

Short description
Claves de identificación | Morfología | Morfometría
Small adult size; Body tapering, anterior trunk wide and somewhat depressed; tail long and slender, almost circular in cross-section at second dorsal-fin insertion; no lateral keels; no postnatal ridge between anal fin base and lower caudal-fin origin; no longitudinal ridges on dorsal surface, no obvious lateral ridges. Head short, wide and somewhat depressed, more so between eyes and ventrally; narrowly pointed, not upturned or knob-like in lateral view (slightly upturned in some paratypes); in dorsoventral view anterior to gill openings broadly parabolic; subocular ridge evident, variably angular. Eyes small, spindle-shaped; dorsolateral on head, with lower edges well medial to lateral head margin in dorsal view; subocular ridges weak, not well defined, subequal in length to eye, almost a spiracle length from eye margin; no supraorbital crest (Ref. 59315).
Body shape (shape guide): elongated.
Reported to be caught occasionally by demersal fisheries, but no depth distribution information is available (Ref. 59315).
