The narwhal, or narwhaul (Monodon monoceros), is a medium-sized tuithed whale that lives year-round in the Arctic. Ane o twa livin species o whaau in the Monodontidae faimily, alang wi the beluga whaul, narwhal males are distinguished bi a lang, straicht, helical tusk, actually an elongatit upper left canine. Foond primarily in Canadian Arctic an Greenlandic watters, rarely sooth o 65°N latitude, the narwhal is a uniquely specialized Arctic predator. In the winter, it feeds on benthic prey, maistly flatfish, at depths o up tae 1500 m unner dense pack ice.[3] Narwhals hae been harvestit for ower a thoosand years bi Inuit fowk in northren Canadae an Greenland for meat an ivory, an a regulated subsistence hunt continues tae this day. While populations appear stable, the narwhal is particularly vulnerable tae climate chynge due tae a narrow geografical range an specialized diet.[4]
