Whales are very large and very, very cool marine mammals found across all the world’s oceans. There are two broad types of whales: baleen whales and toothed whales. Simply put, baleen whales have baleen plates instead of teeth that collect plankton, and toothed whales have teeth that allow them to eat larger fish and marine life.
Whales are well-known for their blowholes. Since whales are mammals, they must breathe air regularly and so, blowholes, like human nostrils, give whales the perfect access to the fresh air around them (above the water, that is!).
While whales were once used heavily for their resources, like blubber, teeth, meat, and so on, they are now seriously protected from hunting. Whale watching, however, is still ever-popular and allows humans to see these beautiful creatures without harming them.
