Elephant seals, the earless super swimmers who can spend more than 1.5 hours underwater without surfacing for a breath, returned to Point Reyes in the early 1970s after being absent for more than 150 years due to overhunting.

Early autumn is the perfect time of year to see loggerheads hatching and heading out to the ocean. Mature females often return to the beaches where they were born to nest, which may be 35 years later. Other than that, sea turtles never return to land.

These bright-colored reefs are found in Biscayne National Park and are some of the most easily accessible to see in the world. The above Elkhorn corals are known as the “giant redwoods of the reef,” but are now threatened and an estimated 90-95% of cover has been lost since 1980.

Typically found at depths of below 200 feet (and even up to 8,000 feet), sixgills generally avoid shallow waters. However, they have been sighted in waters as shallow as 20 feet in Puget Sound— providing a rare opportunity to learn more about these elusive creatures, which have been around since before the dinosaurs.

Both horned and tufted puffins are found in Kenai Fjords and are equally comfortable on land or in the water, as they swim to catch prey. These adorable birds form long-term pair mating bonds.

While alligators are much more common throughout the Southeastern United States, American crocodiles are rarely seen. Finding them in Everglades National Park is a snap – the park is the only place in the country where both crocodiles and alligators live together.

A group of river otters is known as a romp; given their playful nature, it's a very accurate description. River otters are found on the outer coast peninsula in Olympic where they forage for food in the intertidal pools.
