How do whales survive off plankton?
This is how whales can easily eat a few tons of krill every day. In a nutshell, whales, some of the largest creatures on the planet, can survive by eating krill because they eat so many of them.
What do whales provide for plankton?
Research shows that whales bring it to them! Because whales can’t “poop” under pressure, they take their bathroom breaks at the ocean’s surface and by doing so, supply phytoplankton with life giving nutrients like iron, nitrogen and phosphorus.
Why do whales only eat plankton?
The primary reason why baleen whales are able to get so large is that instead of feeding on larger organisms, where there’s ultimately less available energy, they focus on trophic layer 2 of this monumentally productive system, and eat the zooplankton directly.
How does a whale feed on zooplankton?
Generally, baleen whales strain large volumes of ocean water through their baleen plates, trapping the food on their baleen. Their food (tons of krill, other zooplankton, crustaceans, and small fish) are licked off their baleen using their tongue and swallowed.
Why do whales not eat big fish?
There is plenty of krill in the ocean. One of the main constraints to eating, for baleen whales, is to open their mouths wide enough to swallow massive amounts of krill-containing water.
Why is whale poop so expensive?
Why is it so valuable? Because it’s used in the high-end fragrance industry. Ambergris was the main ingredient in a super-expensive, 200-year-old perfume originally made by Marie Antoinette.
How much is a whale worth?
One whale is worth thousands of trees — and about two million dollars, according to a recent study by the International Monetary Fund. But how do we calculate the value of a whale? Whales can help fight climate change and provide an ecosystem service worth millions of dollars.
Where does all the water go when a whale eats?
An adult blue whale takes up to 10,000 gallons of water into her mouth at one time while she’s eating. She doesn’t drink all that water, though; the baleen in the whale’s mouth filters the food and the whale pushes most of the water out.
Can a human survive in a whale?
As you have probably gathered by now, even though it is technically possible to survive being swallowed by a whale, it’s extremely unlikely. But luckily for us, whales are generally not that interested in humans. If you are going to worry about anything eating you in the water, it should probably be sharks.
How are whales and phytoplankton related to each other?
Whales have a symbiotic relationship with sea algae known as phytoplankton. Through photosynthesis, phytoplankton consume carbon dioxide from the atmosphere and release oxygen as a waste product. As land based creatures, we are well familiar with the plants around us that produce oxygen such as grass and shrubs through to the Amazon rain forests.
What kind of food does a baleen whale eat?
And in turn, baleen whales eat the krill. It had already been suggested that whales recycled iron in the ocean by eating it in krill and making it available to phytoplankton in faeces. But until this study, no one had analysed whale faeces to confirm if it indeed contained significant quantities of iron.
Why is whale poop important to the ocean?
Whale poop is vital to ocean’s carbon cycle. Advertisement. Saving endangered baleen whales could boost the carbon storage capacity of the Southern Ocean, suggests a new study of whale faeces. Whale faeces once provided huge quantities of iron to a now anaemic Southern Ocean, boosting the growth of carbon-sequestering phytoplankton.
How are whales important to the marine ecosystem?
Whales contribute toward more than half the air that we breathe. Whales play a vital role in providing the essential nutrient food source needed by phytoplankton. Phytoplankton form the base of the marine food chain and without it marine life cannot exist. All fish in the oceans depend on phytoplankton, whether directly or indirectly.

How does whale faeces help the ocean ecosystem?
Since whale faeces is fairly liquid and less dense than sea water, it floats to the surface as plumes where it is readily available to the phytoplankton and innumerable organisms that rely on their nutrient plumes for survival.
How does a phytoplankton get its energy?
Phytoplankton make their energy through photosynthesis, the process of using chlorophyll and sunlight to create energy. Like other plants, phytoplankton take in carbon dioxide and release oxygen. Phytoplankton account for about half of the photosynthesis on the planet, making them one of the world’s most important producers of oxygen.
Where can you find Plankton in the sea?
In addition to phytoplankton and zooplankton, two even smaller kinds of plankton can be found floating in the sea. Bacterioplankton are bacteria and virioplankton are viruses. Plankton can be found in saltwater and freshwater. One way to tell if a body of water has a large plankton population is to look at its clarity.
