Gray whales like this one migrate up to 10,000 miles a year, from the warm waters of Baja California to their feeding grounds in the Bering Sea.
Whales are warm-blooded creatures that nurse their young.
There are two types of whales: toothed and baleen. Toothed whales, as the name suggests, have teeth, which are used to hunt and eat squid, fish, and seals. Toothed whales include sperm whales, as well as dolphins, porpoises, and orcas, among others. The narwhal’s “horn” is actually one long tooth protruding through its lip.
Baleen whales are larger than toothed whales, for the most part. They include blue whales, humpbacks, right whales, bowhead whales, and others. They feed by straining tiny shrimp-like creatures called krill through the fringed plates of long, fingernail-like material called baleen attached to their upper jaws.
Whales, particularly humpbacks, produce otherworldly vocalizations that can be heard
