Balaenoptera – Rorquals

Home to all giant whales other than the Humpback whale

Balaenoptera belongs to the Rorqual group of baleen whales that are different from the other species by ventral grooves extending from the chin to the throat and belly. These ventral grooves allow the mouth cavity to inflate into the throat, which makes gulp-feeding possible.

The Balaenoptera genus includes the largest animal ever, extant and extinct: the mighty blue whale.

Despite being some of the largest animals ever to have lived on earth, these whales surprisingly feed on small animals that include microscopic organisms such as zooplankton and phytoplankton, along with some species of this genus consuming crustaceans and small fishes in their diet.
