Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Scyliorhinidae
Etymology: Halaelurus: Greek, als = salt, charm, elegance + Greek, ailouros = cat (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 37 - 250 m (Ref. 6871). Deep-water; 21°N - 26°S
Indo-West Pacific: Gulf of Aden and off Somalia; also known from Viet Nam, the Philippines, Indonesia, and Western Australia. However, the extensive range needs further confirmation, for several species may be involved (Ref. 47737).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 35 - ? cm
Max length : 48.0 cm TL male/unsexed; (Ref. 244); 47.0 cm TL (female)
A little-known but wide-ranging bottom-dwelling shark found on continental and insular shelves (Ref. 11146). Probably caught with bottom trawls (Ref. 30573). Live-bearing (Ref. 50449).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Up to 4 egg capsules may be found in an oviduct but it is uncertain whether these hatch inside the oviduct or if the eggs are laid (Ref. 244). Live-bearing (Ref. 50449).

Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (0.00170 - 0.00646), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.3 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (46 of 100) .
