Softskin Slickhead
Rouleina attrita
Rouleina attrita, the softskin smooth-head or softskin slickhead, is a species of fish in the family Alepocephalidae.
Its specific name is from the Latin attrīta ("bruised, worn away"), presumably referring to the mutilated or decomposed state of the type specimens.
