How many belugas are there in the world?
- The International Union for Conservation of Nature estimates that there are over 150,000 Belugas worldwide. Do Belugas have any predators? Polar bears can become a threat during the winter when open stretches of water close up with ice. A Beluga can become trapped too far from open water, and pulled out onto the ice by a bear.

Where do belugas live in winter?
- They move south in the fall as the ice forms and then return to feed again in the spring, as the ice breaks up. They can also be found near river mouths, and sometimes even venture up river. Belugas feed on a variety of fish species, such as salmon and herring, as well as shrimp, crabs and mollusks.
