Amazing Facts That Will Change How You View Whales! | AmazingEarth

Whales are large, intelligent, aquatic mammals. They breathe air through blowhole(s) into lungs (unlike fish who breathe using gills). Whales have sleek, streamlined bodies that move easily through the water. They are the only mammals, other than manatees (seacows), that live their entire lives in the water, and the only mammals that have adapted to life in the open oceans.

Whales roam throughout all of the world’s oceans, communicating with complex and mysterious sounds. Their sheer size amazes us: the blue whale can reach lengths of more than 100 feet and weigh up to 200 tons—as much as 33 elephants.

Despite living in the water, whales breathe air. And like humans, they are warm-blooded mammals who nurse their young. A thick layer of fat called blubber insulates them from cold ocean waters.

Some whales are known as baleen whales including blue, right, bowhead, sei and gray whales. This refers to the fact that they have special bristle-like structures in their mouths (called baleen) that strains food from the water. Other whales, such as beluga or sperm whales, have teeth.

The effects of climate change will be felt by most marine creatures, and whales are certainly not excluded. Sea level rise and changes in sea temperature will leave whales quite vulnerable, and they may not be able to adapt quickly enough to survive. Arctic and antarctic whale habitat faces a particular threat from climate change. Whale food sources will also face challenges, such as a decline in krill population, which is the main food source for many large whale species.
