Do beluga whales have backbones?
yes they do
Beluga whales, like all whales, have a blowhole leading to their lungs on top of their head ti breathe when they reach the surface of the water. When the beluga whales are in the polar regions, the surface will be covered in ice, and unless the beluga whale finds a hole in the ice to surface and breathe, it will drown and die.
If You Mean That "Are Killer Whales Endangered?" Then No. There Are Alot Of Them At The Coast Of Vancouver, Every Zoo In BC Has "Beluga Whales." Why? Because They Are The Most Friendliest Whales They Are Great For Dance Stuff Too, That's Why Vancouver Also Puts On Shows In The Zoo With Beluga Whales.
