NAVIGATING OUR WATERS

About Our Region


THE SALISH SEA

The Salish Sea is a body of water spanning the border between British Columbia and the U.S. state of Washington. It covers 42,000 sq miles from Olympia, Washington, to Campbell River in British Columbia. The Salish Sea is the conglomeration of all the waters of the Strait of Juan de Fuca, the Strait of Georgia, the San Juan Islands, and Puget Sound.

PUGET SOUND

Puget Sound is a maze of waterways extending 90 miles south from Admiralty Inlet to Olympia, Washington. Its glacially carved channels divide the Olympic and the Cascade mountain ranges.

Salmon-eating orcas, also known as “resident” orcas, have smaller and more defined traveling ranges, historically spending months in a specific area. They travel in extended family groups that can exceed 20+ whales. Typically, resident orcas spend their entire lives traveling with their mothers. They interact, socialize, and breed with other members of the resident pods but do not interact with the mammal-eating population. Adult salmon-eating orca in the Salish Sea need around 200 pounds of food daily and rely on Chinook salmon for more than 75% of their diet. Resident orcas occur in various places along the Pacific Northwest coast, with a genetically distinct population who spend part of their time in the waters of the Salish Sea, known as the Southern Resident Killer Whales or SRKW.

This community is comprised of three extended families: J, K, and L Pods, and are one of the best-studied whale populations in the world. Unfortunately, this population is critically endangered, with fewer than 75 individuals remaining. Historically, the Southern Residents spent 4-7 months of the year in the Salish Sea. However, numerous environmental factors have caused a sharp decline in Chinook salmon populations, and now these orca can no longer find sufficient food. As a result, Southern Residents must now travel farther out and for longer periods in an effort to survive. In addition, nearly one-third of the population was forcibly removed from the Salish Sea during the 1960s and 1970s for entertainment purposes by marine parks. Today, due to humanity’s notorious arrogance to their needs, the population is listed under the Federal Endangered Species Act.

Mammal-eating orcas, also called Bigg’s or “transient” orcas, travel the coast between Alaska and California in small pods, usually consisting of a mother and her offspring. Their primary prey in the Salish Sea are harbor porpoises and harbor seals, although sea lions and minkes are sometimes on the menu.

Bigg’s mammalian diets are a key factor in their way of life, defining their culture, travel patterns, and even vocalizations. Unlike the Residents, Bigg’s populations are currently in a stable growth pattern, having an estimated 450+ individuals with a steady annual growth rate. This stable growth can be partially attributed to their diet, with their marine mammal food resources also having reliable and healthful population statuses.

Pacific Gray whales have the longest migration of any mammal on the planet, traveling ten to twelve thousand miles annually. They spend their summers feeding in the waters just south of the Arctic Circle and their winter breeding season in the warm waters near Baja. Since 1990, around two dozen of these whales have been observed diverting their route and taking a “pit stop” to the Pacific Northwest during their Northern migration. These individuals are fondly referred to as the “Sounders.”

The average adult gray whale reaches 50 feet and weighs up to 35 tons. They have robust bodies that are mottled gray, marked with barnacles and yellow patches of Cyamidae, a crustacean that lives on some whale species. In the Salish Sea, gray whales feed on the abundant ghost shrimp in the sandy sediments close to shore, filtering mouthfuls of mud and sand through their baleen plates.

Once an extremely rare sight in the Salish Sea, humpback whales are becoming frequent visitors here as their Pacific populations recover from the days of commercial whaling. Humpbacks are migratory, with our Salish-feeding population spending their summers along the Pacific Northwest coast and then returning to their winter breeding areas either in Hawaii or off the coast of Mexico and Costa Rica.

They can reach up to 60 feet in length, weigh up to 33 tons, and have the longest pectoral fins of any whales, which are usually much lighter in color than the rest of their bodies. They have dark gray backs with a small dorsal fin perched atop a rounded hump, for which they are named.

Minke whales are one of the smallest baleen whales, capable of reaching speeds up to 25mph! Also known as a ‘lesser finback,’ minkes are usually solitary, but may be seen in groups in areas where food is abundant. They are dark gray to black, have a rather sickled dorsal, and often have a pale chevron behind their heads.

Adults grow to an average size of 30 feet and weigh between five and ten tons. Like other baleen whale species, female whales tend to be larger than their male counterparts.

These relatively shy animals are the second smallest cetacean, rarely growing more than five feet in length. Their small size makes them challenging to spot in choppy seas, but they are easily visible when surfacing in calm waters. Unlike populations in the rest of the Northern Hemisphere, those who live in the Salish Sea remain here year-round instead of migrating. They may be seen traveling alone or in small groups of around 2-5, typically.

Harbor seals are the most abundant marine mammal in our area and can be found in any of our Salish Sea waterways.

Their distinct torpedo shape assists in their hydrodynamic swimming and is a result of a thick layer of blubber that insulates them from cool waters. Their spotted fur varies from nearly white to almost black, with any color or pattern in between. Adults average six feet in length and can weigh up to 350 pounds.

These seals are incredible hunters with the capability to dive up to 600 feet deep and stay submerged for over 25 minutes to forage for foods such as fish, mollusks, and crustaceans.

Steller Sea Lion

The Steller sea lion is the largest of all sea lion species. Adult males can reach lengths of up to 11 feet and weigh more than 2,000 pounds, while females typically grow to nearly eight feet and weigh around 800 pounds. As males mature, they develop a distinctive thickened neck and mane. Steller sea lions are opportunistic feeders and are capable of diving to depths exceeding 1,000 feet.

Sea lions differ from their seal relatives in several notable ways. Most visibly, they possess external ear flaps, known as pinnae, on either side of the head. They also have elongated necks and long, powerful front flippers, which they use both for propulsion in the water and for supporting their upper bodies on land. Unlike true seals, sea lions can rotate their hind flippers forward beneath their bodies, allowing them to move on land with a four-limbed, almost quadrupedal gait.

While it is possible to see both, it is almost exclusively male California sea lions who are seen here in the Salish Sea. Most females remain at their breeding grounds in California year-round, while the males migrate north. They stay from fall through late spring, feeding on fish and preparing for the summer breeding season.

California sea lions are dark brown and appear black when in the water. At maturity, the males also develop a prominent raised forehead called a sagittal crest. Smaller than Steller’s, adult males can reach lengths of eight feet and weigh over 1,000 pounds, while females typically measure six feet in length and can weigh up to 250 pounds.

Salmon are anadromous fish, meaning they are born in fresh water, migrate to salt water for their adult lives, and at the end of their lifecycle return back to their natal fresh waters to spawn. After the returning adults reproduce, they die, their bodies providing vital nourishment back to the river system. On average, a female salmon will lay approximately 4,000 eggs, but statistically, only two will survive to return to their spawning grounds. The importance of salmon in the Pacific Northwest ecosystem cannot be overstated. Over 130 species rely on salmon for all or part of their diet, including the endangered Southern Resident Orcas, who rely on Chinook salmon for 75% or more of their diet.

Moon jellies

The Salish Sea is home to many jellyfish species, from tiny, translucent Sea Acorns to the large Lion’s Mane jelly that can reach 7 feet in diameter. Jellyfish use stinging barbs to ensnare their prey. Smaller species feed primarily on plankton, while larger species may also eat small fish or even other jellyfish. The most common jellyfish we spot on our travels are the Lion’s Mane, Moon, and Fried Egg jellyfish, named for its bright yellow center, like a freshly cracked egg.

Bald eagles are large birds of prey with wingspans that can stretch over seven feet and have a weight of up to 15 pounds. Females are typically about 20 percent larger than males. They are opportunistic feeders eating anything from carrion to live fish. Eagles’ eyesight surpasses human capabilities by as much as eight times, using this ability to track fish and small mammals from the air.

Bald Eagles mate for life and return to the same nesting site each year. Adult bald eagles are dark brown with striking white heads and tails. Juvenile bald eagles are mottled brown with white patches on their chest and wings and won’t grow their white head and tail feathers until between three and five years of age. Bald eagles, once threatened by hunting and pesticides, have thrived and rebounded thanks to protective measures.

These raptors live around fresh and salt water, eating almost exclusively live fish. They can sometimes be confused with bald eagles, but are smaller, with a wingspan of five feet and weighing only about three pounds. Ospreys showcase remarkable adaptations for fishing, including reversible outer toes that facilitate a secure grip on their fish prey.

Ospreys are also known as “seahawks.”

Great Blue Herons are arguably the most distinct and recognizable birds in the Pacific Northwest. Despite their large appearance, these birds are only about 5-6 pounds. They have a tall and slender build, standing around 4 feet tall, with a wingspan that can extend up to 6.6 feet. Their plumage is predominantly blue-gray, with a white face and a black stripe extending from the eye to the back of the head. A year-round resident of this region’s bays, salt marshes, and rocky coasts, these birds stalk through the shallow water on slender legs while plunging their long, sharp bills under the surface to capture fish, frogs, and other small aquatic animals.

Three different species of cormorants commonly occur in the region. Cormorants are dark in color with colorful, bare facial skin, set-back legs, and long hooked bills. Unlike most water birds, cormorants do not have the same waterproofing for their feathers. This allows them to become waterlogged, capable of diving to depths of 200 feet or more to capture herring and other small marine prey.

Common murres are oftentimes compared to penguins in their appearance, going so far as having a nickname of “flying penguins.” Despite this comparison, these birds are actually part of the auk and puffin family. When it comes to nesting season, adult breeding pairs will incubate a single egg with no nest on barren rocky cliffsides. To mitigate potential egg loss, they have adapted their eggs to a more elongated profile, lessening the potential for it to roll off the cliff’s edge.

Rhinoceros auklet

Sporting a dark plumage, these medium-sized birds feature a striking white facial plume and a unique bill with a prominent “horn” during the breeding season. Much like many of their alcid relatives, rhinoceros auklets breed in colonies on rocky islands, creating nested burrows by utilizing their robust bills and claws.

These birds will primarily supply their nest with food only at night, presumably to protect their nest from being robbed by gulls or other birds.
