Ever feel like the world is passing you by? It's okay to take a break, like this northern elephant seal in Monterey Bay National Marine Sanctuary! Each winter, thousands of northern elephant seals migrate to California beaches to breed. These seals need plenty of rest and plenty of space -- when watching them, always stay back at least 100 feet and use binoculars if you want a closer look!

Happy Whale Week! National marine sanctuaries are safe havens for humpback whales. Each winter, thousands of humpback whales migrate to Hawaiian Islands Humpback Whale National Marine Sanctuary to mate, calve, and raise their young, while each summer, others travel to Stellwagen Bank National Marine Sanctuary to feed. These whales can also be spotted in many sanctuaries in between! These protected areas are spectacular places to whale watch -- but always be sure to give the whales plenty of space. Learn more:
