Researchers at the University of Tokyo and their collaborators discovered passive feeding behavior among a type of baleen whale called a Bryde's whale foraging in the shallow waters of the upper Gulf of Thailand in Southeast Asia. The tread-water feeding behavior reported in the study contrasts with the active method of lunge feeding, reported in many previous studies, indicating rorqual whales—a group of baleen whales of the family Balaenopteridae, which includes the Bryde's whale—modify their foraging strategy according to their environment.
