If you think you have a long way to go on the school bus each day, check out marine animals. Many travel huge distances in search of food, a mate, or birthing grounds. Which migratory master wins your stamp of approval?
Gray Whale In its lifetime, the average gray whale commutes over 400,000 miles — the equivalent of a trip to the moon and back. Each year, gray whales go back and forth between their feeding grounds in the Arctic to breeding grounds off the coast of Baja California. They spend six months of the year just traveling!
Copepod You might think traveling up and down 3,000 feet in the ocean in twenty-four hours is not such a big deal. But for an animal .02 inches long, that's the equivalent of a human running two marathons each day. Why do copepods haul such long distances? At night, when it's harder for most predators to find them in the dim light, copepods travel up from the depths of the ocean to feed on the plentiful plankton near the top. Then, when the sun comes up in the morning, they travel all the way back down to the dimly lit deeper ocean. Too bad there's not a vertical migration competition in the Olympics!
Pacific Loggerhead Although it's heading to a beach in Japan, life is no day at the beach for this migrating Pacific loggerhead sea turtle. It has got more than 7,000 miles to travel from its feeding grounds in Mexico to its nesting ground in Japan. The journey takes 8-12 months! Sea turtles migrate so they can lay eggs and nest near the area where they were born. On the way, they face every possible threat — sharks, fishing nets, and hunters. You could say that migration is more like an obstacle course than a pleasure trip for this beautiful sea creature.
