rorqual

The only other rorqual to do so—the blue whale—raises the flukes slightly or not at all.

He came out to meet me upon the back of a mighty 'rorqual,' and a body-guard of four hundred picked narwhals swam before him.

There is another kind of whale, called the lesser rorqual, which only grows to the length of about twenty-five or thirty feet.

The rorqual feeds partly upon the small creatures which it captures by means of its whalebone strainer, and partly upon fishes.

That of the extinct Halitherium recalls the pelvis of the Rorqual.
