Elasmobranchii (sharks and rays) > Rajiformes
(Skates and rays) > Anacanthobatidae
Etymology: Anacanthobatis: Greek, ana = up + Greek, akantha = thorn + Greek, batis, -idos = a ray (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 230 - 322 m (Ref. 5578). Deep-water; 24°S - 30°S, 29°E - 40°E (Ref. 57365)
Western Indian Ocean: known only from southern Mozambique to Durban, South Africa.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 29.0 cm TL male/unsexed; (Ref. 95335)
(total): 0. A brown-spotted legskate with smooth skin and a short slender tail less than body length; snout angular with tiny filament; pectoral disc with rounded corners; no large thorns on denticles except for alar spines on adult males (Ref. 5578). Legskates have pelvic fins separated into a mobile leg-like front lobe, and a rear lobe that may be fused to the tail base (Ref. 5578). Mottled brown and white with scattered ocelli dorsally; uniform pale ventrally (Ref. 6510). Papillae and rostral filament dark brown (Ref. 6510).
Possibly the smallest southern African skate (Ref. 5578). Found on the upper slope (Ref. 5578).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this BS (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153
