Balaenoptera edeni, also known as Bryde’s or Bryde’s whale, is a species of baleen whale found in tropical and subtropical waters around the world. It is one of the smallest whales of the genus Balaenoptera, with an average length of 12-14 metres and a weight of 13-23 tonnes.

The Bryde’s whale has a long, slender body with a small, narrow head. Their colouring varies from dark grey to grey-brown, and they have a series of throat folds that expand when feeding. They feed on a variety of prey, including krill, small crustaceans and fish.

These whales are solitary animals or are found in pairs, but are known to gather in feeding groups where there is a large amount of prey. They are often seen jumping and performing acrobatics out of the water.

Is an endangered species due to commercial hunting in the past, as well as bycatch in fishing nets and ocean pollution. The species is also vulnerable to declining prey availability due to overfishing. Conservation efforts, including bans on commercial hunting and the creation of marine protected areas, have helped stabilise fin whale populations in some areas.
