Fin whales

Fin whales, Balaenoptera physalus (Linnaeus, 1758), like all rorquals (Family Balaenopteridae, the family that also includes blue whales, Bryde's whales, humpback whales, minke whales, and sei whales) these long, slender whales are much more streamlined than other large whales. They have a pointed snout, paired blowholes, and a broad, flat rostrum (upper part of the head). Their throat grooves, in addition to streamlining their shape, allow their throat area (called the cavum vent-rale) to expand tremendously during feeding. This allows them to consume large amounts of food-laden water which is then expelled through their baleen plates leaving the fish or krill for swallowing. This efficient system enables the largest animals on earth to feed on some of the smallest. Their baleen plates are broad and short and their dorsal fin is falcate (curved). http://marinebio.org/species.asp?id=40 RD
