Are There Sharks in Oregon? Common Species and Safety

Oregon’s diverse marine environment naturally hosts various shark species. While their presence is a regular aspect of the Pacific Ocean’s ecosystem, understanding these animals can help clarify common questions.

Sharks in Oregon Waters

The cold, nutrient-rich waters off the Oregon coast provide an ideal habitat for a wide array of marine life, including various types of sharks. Sharks function as apex predators within this ecosystem, playing a role in maintaining the balance of marine populations.

Their presence signifies a healthy and functioning oceanic food web. Sharks contribute to the ecological stability by regulating prey populations and scavenging, which helps keep the ocean clean.

Species Commonly Found

Oregon’s coastal and offshore waters are home to about 15 shark species. Among the more recognized inhabitants is the Great White Shark, which can grow up to 20 feet long and weigh over 4,000 pounds. These sharks frequent temperate waters between 54 and 75 degrees Fahrenheit, and migrate to Oregon to feed on abundant seals and sea lions, particularly during the fall months near river mouths.

Blue Sharks, characterized by their slender bodies, long pointed noses, and iridescent blue coloration, inhabit these waters. They can reach up to 12 feet in length and roam both open and coastal areas in search of squid, octopuses, and various fish. The Salmon Shark measures between 6 and 10 feet, possessing a stout body that tapers at both ends. These sharks are dark bluish-gray to black with a white underside and dark blotches, thriving in cold-temperate North Pacific waters where they prey on salmon, hake, and squid.

Leopard Sharks, 20 to 50 inches long, are identifiable by their distinctive dark saddle-shaped blotches. These sharks prefer sandy or muddy bays, estuaries, and kelp forests in cool to warm temperate waters, found near the bottom in shallow areas. The Soupfin Shark, a slender species with a long, narrow snout and a bluish-gray to dark gray back, inhabits Oregon’s temperate coastal regions, including kelp forests and rocky reefs.

Minimizing Encounters and Staying Safe

Shark encounters and attacks are very rare along the Oregon coast. Records indicate only one fatal shark attack in Oregon, which occurred in 1975 and was linked to a sea disaster, not a predatory event. Most reported incidents involve sharks investigating surfboards rather than targeting humans.

To reduce the likelihood of an encounter, avoid swimming or surfing near seal and sea lion colonies, as these are primary prey areas for larger sharks. Avoid entering the water at dawn or dusk, when visibility is low and some shark species are more actively feeding. Avoid wearing shiny jewelry, as it might resemble fish scales, and murky water or areas with active fishing can attract sharks.

Swimming in groups offers safety, as sharks prefer solitary prey. If a shark is sighted, remain calm, maintain eye contact, and move smoothly and deliberately towards shore rather than erratic splashing. Most sharks are not interested in humans, and understanding their natural behavior helps promote safety in coastal waters.
