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).

Краткое описание определительные ключи | морфология | морфометрия

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).

Reported to be caught occasionally by demersal fisheries, but no depth distribution information is available (Ref. 59315).

Estimates based on models

Preferred temperature (Ref. 123201): 22.2 - 28.4, mean 27.4 °C (based on 51 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.5 se; based on size and trophs of closest relatives

устойчивость к внешним воздействиям (Ref. 120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
