This grey whale makes an epic migration
Every spring, about 20,000 grey whales make their way north, feeding in the shallow waters off Vancouver Island, British Columbia. It's a vital pitstop for one of the longest migrations of any mammal on the planet!
They spend their winters in the warm waters of Baja California, Mexico, but as spring arrives, set out north, passing Vancouver Island on their way to summer feeding grounds in the seas of Alaska — a 22,000km round trip!
While fuelling up on B.C.'s coast, they scrape the muddy bottom and strain out small invertebrates using their hair-like baleen. Check out the video above to see how they do it!
