Etymology: Halaelurus: Greek, als = salt, charm, elegance + Greek, ailouros = cat (Ref. 45335).
Environment / Climate / Range
Marine; demersal; depth range 0 - 172 m (Ref. 5578). Subtropical; 33°S - 35°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 244); 47.0 cm TL (female)
soft rays: 0. A catshark with a prominent upturned knob on the snout, a broad head, and with no spots on the body (Ref. 5578). Yellow-brown in color, with pairs of broad, vertical, dark brown stripes outlining dusky saddles (Ref. 5578), cream ventrally (Ref. 5510).
Southeast Atlantic: Cape Agulhas to East London in South Africa. Until recently, two species were confused under this name, the present one and the recently described Halaelurus lineatus (Ref. 244).
Found on the continental shelf, from close inshore to deeper water (Ref. 244). Feeds mainly on small bony fishes and crustaceans, also cephalopods and small elasmobranchs (Ref. 244).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, with 6 to 11 egg-cases per oviduct (commonly 6 to 9) at a time (Ref. 244). Egg cases retained until embryos are well-advanced (Ref. 5578).

Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00154 - 0.00651), b=3.11 (2.93 - 3.29), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): Moderate vulnerability (39 of 100) .
