Antarctic krill populations are at risk from warming waters in the Southern Ocean. Researchers have discovered that if sea temperatures continue to warm, the habitat area for krill species could be reduced by up to 20%.
For their eggs to hatch and develop, krill require deep water with low acidity and a narrow temperature range.
Krill are also major source of food for other animals and help to sustain life in the Antarctic region.
The study concluded that animals which don’t travel far to forage, such as fur seals, could also be affected by the loss of krill.
