Description

The sei whale is large, measuring from 39-52 ft (12-18m), weighing between 17-45 tons. The females are larger than males.

There are no commercial whale-watching operations anywhere dedicated to watching this species.

They do not gather in the same areas from one season to the next as most whales do, making them elusive.

They have a more varied diet than most other baleen whales which includes krill, copepods, crustaceans and schooling fish.

They are mostly dark gray or brown, with a prominent dorsal fin.
