Amblyraja hyperborea·Large·Oviparous·Least Concern
The Arctic skate (Amblyraja hyperborea) is a species of ray found near the seabed in cold waters of the Arctic Ocean, surrounding Canada and northern Europe, the northern Pacific, and waters around Antarctica and New Zealand. It is characterized by its gray-brown coloration with large dark spots on its dorsal side, a white underside with dark patterns, and thorns along its back to its tail. This oviparous species feeds on small bottom-dwelling animals.

About Amblyraja hyperborea
The Arctic Skate (Amblyraja hyperborea)
The Arctic skate, scientifically known as Amblyraja hyperborea, is a species of ray that inhabits the cold, deep waters of the Arctic Ocean and surrounding regions. This cartilaginous fish is typically found near the seabed, preferring habitats with rough rocky substrates or cobblestone reefs. Its geographic range extends to the waters around Canada, northern and north-western Europe, the northern Pacific Ocean, and also includes areas surrounding Antarctica and New Zealand.
Physical Characteristics and Reproduction
This species is characterized by its distinctive gray-brown dorsal surface, which is adorned with large dark spots and small thornlets, giving it a coarse texture. The underside is a contrasting white, often marked with dark patterns that may become more prominent with age. Arctic skates are born at lengths of 16–23 centimeters and can grow to a maximum total length of approximately 112 centimeters. A notable feature is the presence of thorns that extend from its back towards the end of its tail. The Arctic skate is oviparous, laying its eggs in distinctive capsules that feature hard horns on each corner.
Habitat and Diet
The Arctic skate typically resides at considerable depths, ranging from 165 to 3,165 meters, with a strong preference for depths below 800 meters. The water temperature in its habitat is usually below 4.0 °C. Its diet consists of a variety of small animals found on the seafloor, reflecting its benthic lifestyle.
Conservation Status
The International Union for Conservation of Nature (IUCN) Red List classifies the Arctic skate as 'Least Concern', indicating that it is not currently facing a high risk of extinction. In New Zealand, the Department of Conservation also lists the species as 'Not Threatened'.
