New organ discovered in rorqual whales is clue to lunge feeding
A whale of a discovery: New sensory organ found in rorqual whales
May 2012. Scientists at the University of British Columbia and the Smithsonian Institution have discovered a sensory organ in rorqual whales that coordinates its signature lunge-feeding behaviour – and may help explain their enormous size.
Rorquals are a subgroup of baleen whales – including Blue, Fin, Minke and Humpback whales. They are characterized by a special, accordion-like blubber layer that goes from the snout to the navel.
