Rorquals are a group of baleen whales that includes the blue whale, fin whale, humpback whale, minke whale, Bryde's whale, and sei whale. They are named for the Norwegian word "ror" meaning "furrow" and "hval" meaning "whale" because of the pleated skin on their throats that expands when they feed. Other words used to describe rorquals include "gulpers" because of their unique feeding mechanism and "rorqual whales" to specify their classification within the whale family. Additionally, some species are referred to by specific names such as the "knob-headed whale" for the sei whale and the "sharp-headed fin whale" for the fin whale. Overall, rorqual synonyms add depth and context to our understanding of these magnificent creatures.
