En - Japanese nylon shrimp.
Maximum body length about 11 cm (females larger), commonly between 6 and 10 cm. Found on
bottoms of sand and mud, at depths from 150 to 625 m, usually around 200 m, or deeper. So far
not fished commercially but sometimes caught in large quantities on the basis of exploratory
deep-water trawling. The moderate size of this shrimp and the fact it is found in not very deep water
suggests that it may have commercial potential with the development of a deep-sea fishery in the
area. Western Pacific, reported from Japan, Taiwan Province of China, the Philippines, Australia,
New Caledonia, Chesterfield Islands, and Hawaii. Often confused with Heterocarpus ensifer A.Milne
Edwards, 1881, H. parvispina, andH. sibogae.
