Bryde's Whale (Balaenoptera brydei)
The Bryde's whale is a baleen whale, more specifically a rorqual belonging to the same group as blue whales and humpback whales. It has twin blowholes with a low splashguard to the front. Like other rorquals, it has no teeth, but has two rows of baleen plates.
Bryde's whales closely resemble their close relative the sei whale. They are remarkably elongated (even more so than fin whales), with the greatest height of the body being one seventh their total length—compared to 1/6.5 to 1/6.75 in fin whales and only 1/5.5 in sei whales.
Bryde's are dark smoky grey dorsally and usually white ventrally, whereas sei whales are often a galvanized blue-grey dorsally and have a variably sized white patch on the throat, a posteriorly oriented white anchor-shaped marking between the pectoral fins, and are blue-grey beyond the anus—although Bryde's off South Africa can have a similar irregular white patch on the throat. Bryde's have a straight rostrum with three longitudinal ridges that extend from the blowholes, where the auxiliary ridges begin as depressions, to the tip of the rostrum.
The sei whale, like other rorquals, has a single median ridge, as well as a slightly arched rostrum, which is accentuated at the tip. Bryde's usually have dark grey lower jaws, whereas sei whales are lighter grey. Bryde's have 250–370 pairs of short, slate grey baleen plates with long, coarse, lighter grey or white bristles that are 40 cm (16 in) long by 20 cm (7.9 in) wide, while sei whales have longer, black or dark grey baleen plates with short, curling, wool-like bristles.
Bryde's whales have an upright, falcate dorsal fin that is up to 46.25 cm (18.21 in) in height, average 34.4 cm (13.5 in), and is usually between 30 and 37.5 cm (11.8 and 14.8 in). It is often frayed or ragged along its rear margin and located about two-thirds of the way along the back. The broad, centrally notched tail flukes rarely break the surface. The flippers are small and slender
