How do i identify a Sei Whale?

They can be identified by their long backs with a tall dorsal fin two thirds of the way along their back. They are around twice the size of a minke whale so noticeably larger and with a much taller dorsal fin than that of a fin whale. Although they do not raise their tail flukes when they dive, they can often leave distinctive “fluke prints” at the surface as they flick their tail flukes up, creating a large flat circle at the surface of the water – a whale footprint!

About Sei Whales

Scientific Name: Balaenoptera borealis

The Sei whale gets its name from the Norwegian word for pollack as their presence is known to coincide with plentiful pollack in the water. They are a member of the rorqual family of whales which includes blue, fin and minke whales, however, unlike other rorquals, Sei whales do not gulp feed, instead skimming the surface open-mouthed feeding on a variety of fish species, squid and plankton.

Book a boat trip during late summer for the best chances to see these beautiful creatures. Sei Whales are more elusive than minke whales but much bigger so they should be easier to spot from the coast. Look across the horizon. Make sure you scan your eyes slowly from left to right while on the boat and take note of anything that breaks the surface of the ocean water.
