California sea lion (Zalophus californianus)

California sea lions are members of the “eared seal” family Otariidae. These pinnipeds live along the rocky Pacific Ocean coastlines of western North America.

They are very social animals and form groups of several hundred individuals onshore. In many areas they have become quite invasive and obnoxious. 

California sea lions are the most recognized pinniped species because they are commonly seen doing acrobatic tricks in shows at zoos and aquariums. While they are known for their intelligence and playfulness, these animals also quite athletic.

In the wild, the California sea lion swims up to 25 miles per hour, which is faster than any other sea lion or seal. This superb speed is related to how they use their front flippers.

Quick Diver

This animal is also an avid diver. When diving deep, California sea lions slow their heart rates to allow them to remain underwater for nearly 10 minutes before surfacing to breathe. This ability gives them an edge in the pursuit of the fish, squid, and shellfish that make up their primary diet.

California sea lions have color vision. They don’t see all colors, however, but are limited to blue-greens of the color spectrum.

Oregon is home to nearly 30,000 black bears, Ursus americanus, America’s most common bear species. They can grow up to six feet long and weight anything from 125 to 500 pounds. In fact, the name “black bear” is misleading, because they can have brown or gray coats.

If you’re on the lookout for bears in Oregon, you’ll only find black bears, since grizzlies haven’t been seen in the state since the 1930s. They make their home in Oregon’s abundant forests, where they create dens for hibernation, climb up trees, and forage.

If you’re really looking to find one, try visiting areas that have been clear-cut and allowed to grow for a few years. They are easier to spot, and they feed on the grass and brush.

They also feed on berries, nuts, and fruits; they can eat small mammals, insects, fish, and amphibians, but they are not usually actively hunting.

The best time to spot a black bear is in the middle of the summer, when their breeding season begins. Males and females will be more active, and yearling bears are becoming independent and can be seen roaming around roads and clear cuts. They are also independent animals, so don’t expect to see many in the same place.

Northern Elephant Seal (Mirounga angustirostris)

Dozens of different species of marine mammals can be found off Oregon’s Coast. Perhaps one of the most distinctive to make its way on shore is the Northern Elephant Seal, the largest pinniped carnivore that occurs along the North Pacific Coast.

This animal gets its name from its size as well as the trunk-like “nose” – known as a proboscis – that is found on males and can be inflated to enhance vocalizations during mating season. Adult female elephant seals can weigh up to 1,700 pounds, and adult males can weigh up to 5,000 pounds!

Unlike other mammals, including humans, that shed hair year-round, elephant seals experience this a one time a year ‘molting.’ They come ashore to shed their first layer of skin and fur. The skin and fur come off in sheets as new skin and fur replace the old.

For a period of time, elephant seals were thought to be extinct after they were killed in large numbers for their blubber. A small group survived off the coast of Mexico.

Thanks to protections in Mexico and the United States, scientists believe there are around 170,000 northern elephant seals today.

Elephant seals do not generally breed in Oregon, but visitors to the South Coast may be fortunate enough to catch a glimpse of one at Cape Arago State Park (near Coos Bay), the only location where elephant seals haul out year round in Oregon.
