Shallow, seaside waters and near the ice edge; sometimes in rivers

The beluga whale is a fairly small toothed whale that is brown-gray at birth and bright white in adulthood. The beluga is one of just two types in the “white whales” family, the other being the narwhal.

Beluga whales are minimal to the Arctic ocean and surrounding waters.They feed in shallow, seaside waters during the summer and near the ice edge in winter.Some populaces undergo long, seasonal migrations, while others are more resident in nature.They eat a variety of fish and invertebrate prey.Killer whalesand polar bearshave been recognized to attack and also eat beluga whales.Scientists believe that belugas may swim far into ice-covered waters to prevent orcasbut the this might put castle in better risk that predation through polar bears.When searching belugas, polar bears usage their incredible toughness to traction them top top the ice surface ar whenever they involved a feet to breathe.
Occasionally, belugas have the right to be observed far inland, swimming up coastal rivers as far as numerous miles.Scientists do not understand if this trips into freshwater room for feeding or for other purposes, yet belugas are apparently unafraid of really shallow water.In fact, part individuals have been recognized to make it through being stranded/beached through patiently wait for the return of the high tide.Belugas are likewise known for their loud, clean vocalizations.They frequently “sing,” and can also be heard over the s surface by civilization in watercrafts or onshore.
Conservation scientists take into consideration the beluga to be near threatened through extinction.Climate adjust is resulting in rapid changes to the Arctic ecosystem that affect beluga habitat, and chemical air pollution in the Arctic is specifically bad, risking the health and wellness of big predators favor this species.These whales room hunted, legally, by indigenous peoples all around the Arctic, yet this recurring hunt is not usually thought come threaten the species.Climate readjust and air pollution are most likely more far-reaching threats to beluga populations, though further research is necessary before accurate predictions have the right to be made.
