Whales feed at deeper levels where krill is found, and their fecal matter, rich in iron, rises to the surface. This action enhances phytoplankton productivity and supports fish populations. Whales, along with krill, form a positive feedback loop, where their populations contribute to the recycling of iron, further boosting phytoplankton growth.

Humpback whales are migratory and only eat during half of the year. [5] During this feeding season humpback whales actively feed for up to twenty-two hours a day. [ 4 ] They do this so they can store enough fat reserves to live through their breeding season when they do not eat at all. [ 4 ]

The explosives-expert veteran's brand-new automobile, purchased during a "Get a Whale of a Deal" promotion in a nearby city, was damaged by a chunk ...
