Etymology: Anacanthobatis: Greek, ana = up + Greek, akantha = thorn + Greek, batis, -idos = a ray (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologie
marien bathydemersaal; diepte 230 - 322 m (Ref. 5578). Deep-water; 24°S - 30°S, 29°E - 40°E (Ref. 57365)

Grootte / Gewicht / Leeftijd
Maturity: Lm ?  range ? - ? cm
Max length : 29.0 cm TL mannelijk / geslacht onbekend; (Ref. 95335)
Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 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
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 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 body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.6 ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming fecundity<100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (19 of 100).
