Definition
Balaenopteridae is the family of rorquals, which are baleen whales characterized by their streamlined bodies and throat grooves that expand during feeding. This family includes some of the largest animals on Earth, like the blue whale. They are fast swimmers compared to right whales. They use baleen plates to filter feed. Think of them as the cheetahs of the whale world, built for speed. 🐆 Unlike the stocky right whales, these whales are sleek and agile.
