Eden's Whale

Eden's whale, also called the Sittang whale, is the smaller form in the Bryde's whale complex, a group of medium-sized rorquals that may be restricted to the Indo-Pacific. It is named for Sir Ashley Eden, a British official in Burma who helped obtain the type specimen. The taxonomy is poorly settled: the two genetically distinct forms, the larger Bryde's whale and Eden's whale, differ in distribution, in preference for inshore or offshore water, and in size, and the name Balaenoptera edeni is commonly used for both (Wikipedia, general account of the Bryde's whale complex).

Bryde's-type whales are baleen whales with twin blowholes and no teeth. Adults in the complex measure about 12–15 m. In the Indian Ocean they are found north of about 35°S, and in the Pacific and northern Indian Ocean they have been seen using tread-water or trap feeding. Because records were made before the group was split, many reports of these whales cannot be assigned to one form or the other (Wikipedia, general account of the Bryde's whale complex).
