Description

The white-dotted skate is a skate (family Arhynchobatidae) of the cold waters of the southern hemisphere. The species grows to about 63 cm and has a rhomboid, flattened pectoral disc in shades of brown with numerous small white spots, which give it its name. It lives demersally on the continental slope, typically between 130 and 434 m depth. Its diet consists of bottom invertebrates and small fishes. Reproduction is oviparous: the female lays angular egg capsules with horn-like points. The species is considered Vulnerable (VU) due to low resilience and fishing pressure. It is harmless to humans (no sting).
