porpessPOR'PESS, n. In zoology, a cetaceous fish of the genus Delphinus, whose back is usually blackish or brown, whence it is called in Dutch, bruinvisch, brown fish; the body is thick towards the head, but more slender towards the tail, which is semi-lunar. This fish preys on other fish, and seeks food not only by swimming, but by rooting like a hog in the sand and mud, whence some persons suppose the name has been given to it. |
