Below you can find a complete list of Northwest Pacific Ocean animals. We currently track 193 animals in Northwest Pacific and are adding more every day!
The Northwest Pacific Basin is a region of the Pacific Ocean. To its west is the Kuril-Kamchatka Trench, which links Russia, Korea, and Japan; to its east is the Emperor Seamount Chain, an underwater mountain range that reaches Hawaii. Its southern border is near the Hawaiian islands of Necker Island and Marcus Island. It is one of the ocean regions where cyclones and typhoons form.
Its primary seas include:
- Sea of Okhotsk
- Kamchatka Shelf
- Bering Sea
- Northern Honshu
- Sea of Japan
- Yellow Sea
- East China Sea
Some of the chief islands of the Northwest Pacific are:
- Aleutian Islands
- Puget Sound
- Kuril Islands
- Japanese Islands
- Vancouver Island
The Northwest Pacific’s range includes tropical islands, but the water in its northern regions is cold. Fish that thrive in these cold waters include the Pacific halibut, salmon of all varieties, and gold country pollock. There are 13 whale species native to the Northwest Pacific.
Its marine life includes gray whales, humpback whales, blue whales, minke whales, and sperm whales. The waters are home to killer whales, bottlenose dolphins, and Pacific white-sided dolphins. Porpoises include the Ball’s porpoise and harbor porpoise.
Its waters are important fishing grounds for mackerels, tunas, shrimps, sardines, milkfish, sea breams, croakers, and seaweed.
One of the most important fish of the North Pacific is the herring. Like sardines and anchovies, herrings are forage fish. They are a vital food source for a huge number of larger fish and endangered marine mammals. Salmons, porpoises, seals, and other animals swarm the waters during herring spawning seasons.
Unfortunately, herring populations have dropped in recent years. Conservation groups along the Northern Pacific coastline are working to restore the population of these critical fish.
Millions of seabirds make their home on the coastlines of the Pacific Northwest. These include auklets, puffins, fulmars, terns, and almost all of the world’s 250,000 red-legged kittiwakes (Rissa brevirostris).
What Is the National Animal of the Northwest Pacific?
As an ocean, the Pacific Northwest is not a country and does not have its own national animal. Listed are the national animals of some countries with coasts on the Northwest Pacific.
- United States: Bald eagle and bison
- Japan: Japanese green pheasant
- Korea: Siberian tiger
Where To Find the Top Wild Animals in the Northwest Pacific
With many whale species, the Pacific Northwest is an ideal place for whale-watching tours. Along the Pacific coastline in North America, there are more than 100 whale watching sites that are part of the Whale Trail Project. Key spots include Sea Lion Caves in Oregon, Cape Flattery in Washington, and Lighthouse Park in British Columbia.
Aside from whales and porpoises, you can spot California sea lions, harbor seals and sea otters.
Fishing and charter boat trips provide an opportunity to visit the many islands of the Pacific Northwest. These islands are feeding grounds for seals, birds, dolphins, otters, and sea turtles.
The islands of the Pacific Northwest are scenic and wooded. They are home to large mammals like wolves, bears and cougars. Camping, fishing, and sightseeing trips to these islands are a great opportunity to see the wildlife and marine life of this region.
The Most Dangerous Animals in the Northwest Pacific Ocean Today
The most dangerous animal is the killer whale or orca. An apex predator in any environment, the killer whale lives everywhere except the Arctic Ocean.
Killer whales feed on whatever is available, including fish, seals, dolphins, and other whales. Wild killer whales are not dangerous to humans. There are no recorded attacks of killer whales on people.

Animals in Northwest Pacific FAQs (Frequently Asked Questions)
What Unique Animals Live in the Northwest Pacific?
One of the Northwest Pacific Ocean’s unique animals is the crested puffin or tufted puffin (Fratercula cirrhata). This cute bird sports black and white feathers with an orange beak and a bright yellow crest. In summer, its talons turn red and the feathers on its face turn white.
Otters: The Northwest Pacific Ocean is home to both river otters and sea otters. River otters divide their time between land and sea. They live on shorelines, riverbanks and the banks of streams. River otters are small and slender.
Sea otters are large and plump. They live in the coldest waters of the North Pacific and spend most of their lives in the water. Sea otters fish and breed in the water.
Both otter species were prized for their fur and almost became extinct. Conservation efforts and hunting bans pulled them from the brink of extinction. River otters have made a recovery, but sea otters were slow to recover and are still endangered.
What Sharks Live in the Northwest Pacific Ocean?
- Blue sharks live in almost all oceans of the world. They can reach 10 to 12 feet.
- Salmon sharks are found in the colder waters of British Columbia and Alaska. They feed on birds, salmon, sea otters and small fish.
- Brown catsharks are small sharks that only reach about two feet. They feed on shrimps, squid and small fish
