A very large North Atlantic whalebone whale (Physalus antiquorum, or Balænoptera physalus). It has a dorsal fin, and strong longitudinal folds on the throat and belly. Called also razorback.
Scientific term (which means 'red whale' or 'furrow') used to describe six of the baleen whales; minke, Bryde's, humpback, sei, fin and blue. The name is due to the whale's method of expanding its throat grooves when feeding when the pink skin can be seen in between.
A group of baleen whales which include the blue, fin, sei, brydes, minke and humpback whales.
any of several baleen whales of the family Balaenopteridae having longitudinal grooves on the throat and a small pointed dorsal fin
baleen whale of the genus Balaenoptera (some experts include the Humpback Whale in this category)
A term used for baleen whales belonging to the genus Balaenoptera, which includes the blue, fin, sei, Bryde's, and the Minke whales. Some include the humpback whale of the genus Magaptera. Some characteristics of rorquals are numerous longitudinal grooves (long throat grooves) on the lower surface of the body, and a dorsal fin.
The rorquals are those baleen whales that are characterized by the presence of conspicuous grooves, or pleats, on their throats. (The word "rorqual" is derived from the Old Norse word for "grooved whale.") Rorquals include the minke, sei, Bryde's, blue, fin, and humpback whales.
Strictly speaking, a baleen whale of the genus Balaenoptera; however, many experts also include the Humpback Whale (genus Megaptera) in this group.
Rorquals are the largest group of baleen whales, with nine species in two genera. They include the largest animal that has ever lived, the Blue Whale, which can reach 150 tonnes, two others that easily pass 50 tonnes, and even the smallest of the group, the Northern Minke Whale, reaches 9 tonnes.
