The Gray Whale Annual Cycle
Teaching Suggestions

Overview
Each winter in the warm waters of Mexico, gray whales give birth, nurse their calves, rest and play before their monumental journey north in spring. They swim 5,000 miles along the Pacific coast from Mexico to the Arctic. The trip ends in the nutrient-rich feeding grounds of the Bering Sea in Alaska to feed. In fall, they travel back to Mexico again to complete a round trip annual journey of 10,000 miles. Gray whales migrate farther than any mammal on Earth.
