Whales and Dolphins of Canada

Whales and dolphins are mammals, not fish.

Scientists think they are as smart as humans!

• Humpback whales communicate by singing songs.

• A dolphin sleeps with only half its brain at a time.

• The beluga is the only whale that can swim backwards.

• The largest animal on earth, the blue whale, can’t swallow anything larger than a beach ball. 

• A sperm whale can hold its breath for more than two hours.
