sea slug

Trepang (sea-slug, Holothuria) and shark-fins are sent to the Chinese markets; also mother-of-pearl, wax and gold dust.

I understand the sea-slug, which the Indians call balate, is thus captured.

A good deal of salt is made, and there is a considerable fishery of trepang (sea-slug) and tortoises for the sake of the shells.

A more beautiful example of a phosphorescent mollusk is presented by a sea-slug called Phyllirho bucephala.
