Distribution

B. amblyops occurs in the northern Atlantic Ocean in latitudes south of 40° N, and also in the southern seas of the Atlantic, in the Indian Ocean and in the Pacific.[5] It is a bathypelagic krill that lives in deep waters below 1,000 metres (3,300 ft).

Description

It is distinguished from the Euphausiidae by several morphological features, the most apparent being that they are not bioluminescent and that their first pair of pleopods is not modified as copulatory tool organs. Also, their eyes are smaller than those of the Euphausiidae. Adults reach a length of 4 to 5 centimetres (1.6 to 2.0 in).[5]
