Where do gray whales live?

According to National Geographic, the two largest gray whale populations are located in the North Pacific Ocean. Gray whales migrate year-round between climate zones, as they prefer to breed in warmer southern waters and live in cooler arctic regions.

The North Pacific pod of whales lives in coastal waters around the Bering and southern Chukchi Seas during the summer. Many of the whales migrate during the winter to the warmer waters off the coast of Mexico. According to the National Oceanic and Atmospheric Administration, gray whales used to live in the Atlantic Ocean, but they were hunted to extinction in the 18th century.
