Entire length from twenty to twenty-five feet.


Much larger than the last species; the body deeper and thicker in proportion to its length. Snout very short and obtuse: upper jaw somewhat longer than the lower, but this last broader than the upper: teeth unequal, conical, a little bent at the summits; varying in number according to the age of the individual, generally about twenty two in each jaw: eyes almost in the same line with the mouth: dorsal fin nearly in the middle, very much elevated, and pointed at the extremity : pectorals very broad, of an oval form: tail crescent-shaped. Skin smooth; glossy black above, white beneath, the two colours meeting on the sides but separated by a well-defined line; an oval white spot behind each eye.

Inhabits the British seas in large herds, and occasionally enters rivers. Is of a fierce and voracious disposition, preying upon the larger species of fish. - Obs. The Delphinus Gladiator and the D. ventricosus of Lace-pede, two species constituted by that author from individuals taken in the Thames, are considered by Cuvier as not really distinct from the above.
