The most commonly encountered species on our trips is the Bryde’s whale. Over the 16 years we have been operating we have encountered many other species which include: blue whales, fin whales, humpback whales, sei whales and Southern right whales. Fin and sei whales are slightly more tricky to distinguish. The best way to distinguish them is to recognize that the dorsal fin on a sei whale is taller than on a fin whale. There is also a white coloration pattern forward of the dorsal fin on a fin whale called a .

It is also similar to Bryde's whale (Balaenoptera edeni), but has only one ridge on the upper surface of the head, whereas Bryde's whale has three. Differs from the fin whale in the more upward-angled dorsal fin (located farther forward on the body), the lack of asymmetrical lower lip coloration, lack of whitish dorsal chevrons, lack of mixed color baleen, and fewer throat grooves ( vs.

Reaching speeds up to miles per hour makes the Sei Whale the fast whale in the water.
