Whale oil is oil obtained from the blubber of whales. [1] Oil from the bowhead whale was sometimes known as train-oil , which comes from the Dutch word traan ("tear drop"). Sperm oil , a special kind of oil used in the cavities of sperm whales , differs chemically from ordinary whale oil: it is composed mostly of liquid wax .
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.
Krill is a rich source of protein and omega-3 fatty acids which are under development in the early 21st century as human food, dietary supplements as oil capsules, livestock food, and pet food. [ 77 ] [ 79 ] [ 84 ] Krill tastes salty with a somewhat stronger fish flavor than shrimp.
The biggest creatures on Earth consume a lot of tiny pieces of plastic.
Krill oil capsules. Krill oil is an extract prepared from a species of Antarctic krill, Euphausia superba.Processed krill oil is commonly sold as a dietary supplement.Two components of krill oil are omega-3 fatty acids similar to those in fish oil, and phospholipid-derived fatty acids (PLFA), mainly phosphatidylcholine (alternatively referred to as marine lecithin).

Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding
Scientists say subtle differences in the colour of seawater will enable them to count tiny - but critically important - Antarctic marine creatures from Space. The target of the new research effort ...
Blubber from whales and seals contains omega-3 fatty acids and vitamin D. [15] Without the vitamin D, for example, the Inuit and other natives of the Arctic would likely suffer from rickets . There is evidence blubber and other fats in the arctic diet also provide the calories needed to replace the lack of carbohydrates which are found in the ...
