Bryde's whale

Balaenoptera edeni/brydei

Local name - Timi

 

Bryde's whales are slim, streamlined, fast swimming and have comparatively little blubber. The Bryde's whale has three prominent bony ridges running from the tip of the snout to the blowholes. There body is bluish-gray with white on the underside. The pectoral fins are relatively short and pointed at the tips, the dorsal fin is curved. Bryde's whales have 250 to 350 baleen plates on each side of their jaw, which are about 42 cm (16 1/2 inches) long. Some of the baleen plates in the front of the mouth are white, while the rest of the plates are black.

The taxonomy and fine-scale distribution of Bryde's whales are uncertain. The large-form of Bryde's whale has a maximum length of 14.6m males and 15.6m in females and does not become sexually mature until it reaches at least 11.2m. This form occurs worldwide in tropical and warm temperate waters. The small form of Bryde's whale can attain sexual maturity at a length of 9.0m and rarely grows larger than 11.5m.

Bryde's whales are not known to undergo long-range seasonal migrations and high productivity in the Swatch-of-No-Ground may support a resident population of this species. During 2004-2008, we made over 150 sightings of baleen whales of which most were confirmed to be Bryde's whales (small form). Bryde's whales are not believed to be facing critical threats in pelagic waters of Bangladesh.
