Biology
provided by Fishbase
Found on the lower continental slope (Ref. 6871), probably most common on deep slopes and at abyssal depths (Ref. 114953). Benthic (Ref. 58426); meso- to bathybenthic, on muddy substrate (Ref. 119696). Adults feed on all kinds of bottom animals (Ref. 3167). Prefer polar temperatures from hatching to maturity and eggs are incubated successfully and regularly in water as cold as 0°C (Ref. 6902). 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 81-125 mm long and 50-80 mm wide (Ref. 41251). Hatching size at 16-18 cm TL (Ref. 114953) (15 cm long in Ref. 119696).

Arctic skate
provided by wikipedia EN
The Arctic skate (Amblyraja hyperborea) is a species of fish in the family Rajidae. It lives near the seabed between 140 and 2,500 m deep in the Arctic Ocean and waters around Canada and northern and north-western Europe, in the northern Pacific Ocean, and in waters surrounding Antarctica and New Zealand.[2]
The Arctic skate is about 1 m long and is gray-brown with large dark spots. Its underside is white with dark patterns. It has thorns in line from back to near the end of its tail. It is oviparous; its eggs are capsules with hard horns on each corner. It eats all sorts of small animals at the bottom of the sea.[2]
Taxonomy
This species was first described by Robert Collett in 1879 and named Raja hyperborea.[3]
Conservation
The Arctic skate is classified as being of "least concern" by the IUCN Red List of Threatened Species.[1]
In New Zealand, the Department of Conservation has classified the Arctic skate as "Not Threatened" under the New Zealand Threat Classification System.[4]
