Blue whales usually feed at depths less than 100 m (328 ft) and no more than 152 m (500 ft). They lunge at dense clouds or patches of krill, expanding their throat grooves to take in as much as 64,252 l (17,000 gal) of food and water in a single mouthful. The water pressure causes their throat pleats to expand. They then partially close their mouth, exposing a fringe of comb-like baleen around the opening and use their tongue to force the water out of the baleen sieve, leaving the krill trapped in the fringes of the baleen plates to be swallowed. Blue whales need to take in 1.5 million calories a day to meet their energy requirements. Adults do this by consuming about 40 million krill a day or 3499 kg (7715 lb).Source: Aquarium of the Pacific
