Whales feed at deeper levels in the ocean where krill is found, but return regularly to the surface to breathe. There whales defecate a liquid rich in nitrogen and iron. Instead of sinking, the liquid stays at the surface where phytoplankton consume it. In the Gulf of Maine, the whale pump provides more nitrogen than the rivers. [30]
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...

A humpback whale was spotted swimming with a severed tail off Washington. These sightings are now serving as reminders of the dangers of marine mammal entanglements and “ human carelessness ...
Rates of human infection are highest in regions where raw or undercooked fish is commonly consumed. For example, the frequent consumption of ceviche in South America, smoked herring in the Netherlands, and pickled anchovies in Spain poses a high risk of infection in these regions. [13]
