Beluga whales are born to stand out—with their unusual white color, they are easy to spot and recognize. They aren’t always this color though. Baby Belugas are born gray or brown, and then fade to white as they mature sexually.

Compared to most whales, Belugas are small, ranging from 13-20 feet in length. They are also unique because they lack a dorsal fin, something most fish and marine mammals have. There are several other things that make Belugas special. They have a more complex way of communicating with one another, utilizing clicks, whistles and clangs, along with other sounds that they sometimes mimic.

Beluga whales can be found in the coastal waters of the Arctic Ocean, and in subarctic waters as well. Belugas almost always live and travel in small groups call Pods. They migrate south when the ocean begins to freeze over and have to move quickly, otherwise they could be trapped under the ice and suffocate—or become an easy target for predators, like Polar Bears.

You might wonder why Beluga whales live in such a frigid environment. They have a thick layer of blubber (which can be as thick as 5 inches!) to help keep them insulated and warm. They also have a hard dorsal ridge along their back and a tough forehead, which helps them to swim through the icy sea water.

Beluga whales are truly amazing and beautiful creatures. Should you ever be near arctic waters, take some time and see if you can spot these fantastic white whales! They are worth the wait.

    Great blog! Do you have any suggestions for aspiring writers?
    I’m hoping to start my own blog soon but I’m a little lost
    on everything. Would you recommend starting with
    a free platform like WordPress or go for a paid option? There are so many choices out
    there that I’m totally confused .. Any recommendations?
    Many thanks!

      Hi there, thank you so much. we work really hard on our blog. we recently switched to an inline blog on our website so we didn’t redirect readers away from our site, you can check that out at sfbaymsi.org/blog. I think from an individual standpoint using a free blog service is great. WordPress is also great. They have so many free templates and template options and fun picture options. The nice thing is you can always play with it and change it up if you want it to have a different look.
      Hope that helps!
