Polar bears and narwhals have a new neighbour in the northern Hudson Bay region, and unfortunately, they are not getting along. Killer whales have begun to move into the region as sea ice melts, being spotted by local Inuit as far north as the Arctic region.

Sea ice in the region has decreased by 11%, and when holes up in the ice, killer whales move in. The species have started targeting the native whale species, hunting their baleen and tusked cousins, especially beluga whales and narwhals.

Killer whales have also been eating seals in the region, which is having an impact on the food security of polar bears. As polar bears struggle due to melting sea ice, more killer whales may move in, and conservationists believe killer whales could eventually become the dominant predators in the region.
