Some couples swear that separate vacations are the secret to marital success. Skeptical? Well, it works for Northern Elephant Seals.
Home for these seals is the Pacific Coast of North America. That's where the females come each winter to give birth to their pups and, a few weeks later, mate with the males that dot the beaches. The adults also come ashore to molt in the summer.
Otherwise Northern Elephant Seals spend their time migrating and feeding. The males venture to the Gulf of Alaska and the Aleutian Islands in their search for food -- squids, octopuses, skates, and the like -- while the females prefer to dine in waters closer to the Hawaiian Islands. Given that these seals make two such trips per year, their migrating totals more than 10,000 miles annually.
