Bigelow's ray (Rajella bigelowi), also called the chocolate skate or Bigelow's skate,[3] is a species of skate in the family Rajidae.[4][5][6] It is named in honour of the oceanographer Henry Bryant Bigelow.[7]
Bigelow's ray lives on continental slopes and deepwater rises around the edges of the Atlantic Ocean. It has been recorded at 367–4,156 m (1,204–13,635 ft), mostly below 1,500 m (4,900 ft).[8][9]
Like all rays, Bigelow's ray has a flattened body with broad, wing-like pectoral fins. The body is sub-rhomboid. It is dark on the dorsal surface, with the outer edges of the disc and pelvic fins shading to a slightly darker colour.[4]
Its maximum length is 55 cm (1.80 ft).[10]
Bigelow's ray feeds on small benthic crustaceans.[11]
Bigelow's ray is oviparous. The eggs are oblong capsules with stiff pointed horns at the corners; they are deposited in sandy or muddy flats.[12]
It is parasitised by Ditrachybothridium macrocephalum (tapeworms of the order Diphyllidea).[10]
