Description

The Antarctic starry skate is a skate of the Southern Ocean, mainly around South Georgia and the Scotia Ridge, and is also reported off Chile. It grows to about 115 cm and has a rhomboid head disc with an exceptionally rough skin set with star-shaped denticles. A bottom-dweller, the fish lives on the continental shelf and upper slopes between about 20 and 350 metres depth and feeds on small benthic invertebrates. The species is oviparous: the egg capsules bear conspicuous horn-like projections at the corners and the embryos live off the yolk. Owing to insufficient data the IUCN lists it as Data Deficient (DD).
