Identification:

Very similar to Bryde's Whale both in size and appearance, but the single ridge on top of the head distinguishes it at close range. Differs from Minke Whale in Size and presence of tall, visible blow, and from Fin and Blue Whales by surfacing sequence and taller, more sickle-shaped fin. On surfacing, dorsal fin breaks the surface at the same time as the blowhole.
