The tail stock is slender. The forehead is rounded, ending in a rounded melon shape or a very indistinct beak. The lower portion of the face is usually slightly concave. The head appears triangular from above and below. The flippers are long, and the tall dorsal fin is back-curved.

    The body is uniformly black or very dark grey on the back and sides and a little lighter on the belly. A small triangular darkening in the face that tapers toward the eyes may be seen in the field. There is a faint grey throat patch. Areas around the lips and the anal and genital regions may be light coloured.
