Description
Bryde's Whales are large streamlined rorquals with dark-grey, brown or blackish colouration and a paler underside. The dorsal fin is small, sickle-shaped and located three-quater way along the back and the flippers are relatively large with concave edges. The diagnostic three rostrum ridges (a longer ridge along the center of the head and two shorter ridges on either side) is only visible on close inspection.

These animals usually feed alone or in mother-calf pairs. They are sometimes inquisitive and will approach and swim alongside boats. They rarely show more than the top of their heads when surfacing.
