Sei whale is the third largest known whale in existence. It belongs to the group of baleen whales and to the group Cetacea. It is one of the fastest whales, reaching speeds of up to 30 miles per hour. This whale species inhabits all oceans and adjoining seas except in tropical and Polar Regions.

They prefer temperate, deep offshore waters. They are very elusive as they do not come very close to land at any time and do not form large groups.
