Krill swim using pleopods. Krill oil contains omega-3s. Krill oil may reduce inflammation. Penguins, seals, whales eat krill. Loss of sea ice impacts krill. Climate change threatens krill populations. Krill fishing increased since 1970s. Krill fishing impacts food chains. Krill fishing is mostly for aquaculture feed. Only small percentage of krill is for human consumption.

What is special about krill?

However, krill are crustaceans, not fish. Krill oil differs from fish oil. Omega-3 fatty acids in krill oil are delivered differently in the body.

Krill are critical in the marine food chain. They serve as a primary food source for many marine species. Krill consume phytoplankton and release carbon-rich fecal pellets. These sink to the ocean floor.

Antarctic krill has the greatest biomass of any non-domestic animal on Earth. There are 85 known krill species assigned to two families. Antarctic krill resemble small shrimp with large black eyes. Their bodies have a reddish-orange tinge. The tail has legs for feeding and grooming.

Krill are actually tiny shrimp-like crustaceans. They are extremely important for the marine ecosystem. Without krill, the ocean could become devastated.

Why do people eat krill?

Krill is rich in nutrients like omega 3 fatty acids, protein, vitamins, minerals, and antioxidants. These nutrients protect against diseases. Krill has more protein than beef.

Humans have not traditionally eaten krill. Public acceptance depends partly on its nutritive value.

In Southeast Asia, krill is widely consumed as shrimp paste. It has a stronger flavor and commands a higher price.

Rising temperatures reduce plankton growth. Plankton loss removes krill habitat and food. Declining sea ice also reduces krill habitat. So when sea ice declines, krill declines. Plankton are marine organisms carried by currents.

Krill are tiny shrimp-like crustaceans. They are important for oceans. Without them, oceans could be devastated. How can whales eat only small crustaceans and get full? How does climate change affect krill?

Krill eat only algae. So krill meat has few pollutants. Krill meat has health benefits like lowering disease risk factors.

Krill can live up to 10 years despite hunting. They avoid Antarctic predators deep below the surface.
