The arctic banshee ululating ominously...
". . . Narwhals can live up to 50 years. They are often killed by suffocation when the sea ice freezes over [...] Narwhals have a relatively restricted and specialized diet. [...] Almost all modern predation of narwhals is by humans. Other predators are polar bears, which attack at breathing holes mainly for young narwhals, Greenland sharks and walruses. Killer whales (orcas) group together to overwhelm narwhal pods in the shallow water of enclosed bays, in one case killing dozens of narwhals in a single attack. To escape predators such as orcas, narwhals may use prolonged submergence to hide under ice floes rather than relying on speed. [...] Many other countries have quotas on catches, which will be important also in newly opening areas caused by decreasing sea ice cover. Narwhals are difficult to keep in captivity. Inuit people, who call a tusked narwhal qilalugaq tugaalik, are allowed to hunt this whale species legally for subsistence. [...] An indirect danger for narwhals associated with changes in sea ice is the increased exposure in open water. In 2002 there was an increase in narwhal catches by hunters in Siorapaluk that did not appear to be associated with increased effort, implying that climate change may be making the narwhal more vulnerable to harvesting...."

Why can't scientists just say they drown when the sea ice freezes over? Also why didn't they add the part where the whale gets trapped under the ice unable to find an opening so it can breathe. Killed by suffocation? I guess we just assume something else isn't putting the choke hold on them.

Interesting point. Less ice more whale hunting?
I hope the Narwhal survives, it's so odd looking that we might like to keep it alive, if only to preserve the Unicorn legend. That's what I mean, it may have lucked into our favour because of its relationship to human folklore and won't need to adapt much at all
