Elasmobranchii (sharks and rays) > Rajiformes (Skates and rays) > Anacanthobatidae (Smooth skates)
Etymology: Anacanthobatis: Greek, ana = up + Greek, akantha = thorn + Greek, batis, -idos = a ray (Ref. 45335).

Environment / Climate / Range Ecology

Marine; bathydemersal; depth range 1000 - 1725 m (Ref. 5578).   Deep-water; 15°S - 30°S

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 21.0 cm TL male/unsexed; (Ref. 5578)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0. A dark smooth-skinned legskate with a long, slender tail greater than body length; snout angular with broad-based filament; pectoral disc with rounded corners and no large thorns or 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). Uniformly grey-black or brownish above, lighter below (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Found on the slope (Ref. 5578). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsule measures 36.0 mm long and 19.0 mm wide (Ref. 41249). Taken only by deep-trawling research vessels (Ref. 5578).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5079   [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), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
