Where they live?

Big blue whales live in all the worlds oceans. Sometimes in groups but mostly alone

When a blue whale exhales, the spray from its blowhole can reach nearly 30 ft (9m) into the air.

Average life Span: 80-90 years

What they eat?

Big Blue Whlaes do not eat humans! They eat krill, which are small shrimplike creatures as small as your finger! .

Blue whales have few predators but are known to fall victim to attacks by sharks and killer whales, and many are injured or die each year from impacts with large ships. Blue whales are currently classified as endangered on the World Conservation Union (IUCN) Red List.

Between 10,000 and 25,000 blue whales are believed to still swim the world's oceans. Aggressive hunting in the 1900s by whalers seeking whale oil drove them to the brink of extinction. Between 1900 and the mid-1960s, some 360,000 blue whales were slaughtered. They finally came under protection with the 1966 International Whaling Commission, but they've managed only a minor recovery since then.
