What do blue humpback whales eat?
But despite their enormous size, blue whales feed almost exclusively on krill – small, shrimp-like crustaceans that grow to about six centimetres. These tiny animals are found in all of Earth’s oceans, swimming in massive swarms, sometimes of more than 30,000 individuals.
What is unique about the feeding habits of the humpback whale?
The researchers found that whales that fed on krill followed a distinct pattern of activity. As Goldbogen hypothesized, they opened their mouth at peak speed and closed it around the time they were back to normal speed. Humpbacks that fed on fish, however, varied their timing.
How do humpback whales feed?

Whales are also kept in captivity, such as the pure-white beluga whales. However, larger species of whales, such as humpbacks and right whales, are too large for any captive display facility to handle.
What is the relationship between blue whale population and the krill population?
Whales form the higher trophic levels of the marine food web and rely on lower level trophic species, like krill, to survive. Changes to the ocean environment could impact the amount of krill available so whales may have to compete for food.”
Do humpback whales eat humans?
