Covers general descriptions focusing on single or multiple species (such as WDFW reports for species of concern, etc.).
Officially known as West Coast transients but increasingly referred to as Bigg’s killer whales, these marine mammal-eating orcas (Orcinus orca) are spending increasing time in the Salish Sea to consume their marine mammal prey including harbor seals, Steller sea lions, and harbor and Dall’s porpoise. They range from Southeast Alaska to California, but over the last 15 years more members of the population are spending increasing time in the inland waters of Washington State and British Columbia (Houghton et al. 2015, Shields et al. 2018). They have no predators (except perhaps occasionally other Bigg’s killer whales - see Towers et al. 2018), but are at risk from anthropogenic effects, including toxics and noise pollution (Ford et al. 2007).
There are more than a half dozen species of skeleton shrimp in Puget Sound. The Washington State Department of Ecology profiles this unusual crustacean in its Eyes Under Puget Sound series.
The Orange Sea Pen, also called the Fleshy Sea Pen or Gurney’s Sea Pen, resembles a colorful autumn tree waving in the “breeze” of moving water currents. Article courtesy of the Washington Department of Ecology's Eyes Under Puget Sound series.
The genus Sternaspis is comprised of sedentary invertebrates with short and thick anterior setae. The dumbbell worm (Sternaspis affinis) can be found on the West Coast of North America, from Alaska to the Gulf of California.
The Doto is a species of sea slug, also known as a nudibranch. It is a marine gastropod in the family Dotidae. This species was first discovered in British Columbia and has been reported as far south as Santa Barbara, California.
Priapula are a small phylum of small, worm-like animals found in Puget Sound. They occur in most seas, both tropical and polar, at a variety of depths, from shallow coastal waters to as far down as 7,200 meters.
Sea pens are marine cnidarians that belong to the order Pennatulacea. They are colonial organisms, composed of specialized polyps.
With its striking plumage and brilliant orange bill, the Tufted Puffin is an iconic seabird well known to native peoples, fishermen, and coastal communities throughout its range in the temperate and sub-arctic North Pacific. Though pelagic in winter, puffins gather on islands and headlands during spring and summer to breed and raise their young. They are members of the auk family, with stocky bodies adapted to “flying” underwater as they dive in pursuit of a wide range of fish and invertebrate prey. Nesting Tufted Puffins range up to 100 km from their breeding colonies to forage for their nestlings, and are famed for carrying 20 or more small fish at one time, neatly lined up and carried crosswise in their large, brightly colored bills.
Harbor seals (Phoca vitulina) are the most commonly seen marine mammals in the Salish Sea and can be found throughout the region year round. They have been intensively studied within the Salish Sea and this species profile provides an overview of what is known about them. It was produced for the Encyclopedia of Puget Sound by the SeaDoc Society.
Can Puget Sound claim a new species? Ribbon seals were not previously thought to venture into the Salish Sea, but a series of sightings in Puget Sound in 2012 expands their potential range. Scientists are keeping an eye out for future sightings.

Eelgrass (Zostera marina L.) is an aquatic flowering plant common in tidelands and shallow waters along much of Puget Sound’s shoreline. It is widely recognized for its important ecological functions, and provides habitat for many Puget Sound species such as herring, crab, shrimp, shellfish, waterfowl, and salmonids.
This is the executive summary from a technical report produced for the Puget Sound Nearshore Partnership on Valued Ecosystem Components (VEC). The entire document is included as a PDF with this summary.
Canadian and U.S. governments differ on special status for bocaccio in the Salish Sea.
The following is an alphabetical list of marine invertebrates occurring in Puget Sound and adjacent regions. It is taken from the book Keys to the Marine Invertebrates of Puget Sound, the San Juan Archipelago, and Adjacent Regions by Eugene N. Kozloff. This list is provided with permission of the author.
The Encyclopedia of Puget Sound species library now includes a list of species of concern in the Salish Sea watershed. The list was created by Joe Gaydos and Nicholas Brown of the SeaDoc Society, and was released as a paper presented as part of the Proceedings of the 2011 Salish Sea Ecosystem Conference in Vancouver, BC.
Three distinct groups of killer whales (Orcinus orca) occupy the coastal waters of the northeastern Pacific. These groups—northern and southern residents, transients, and offshores—are distinguished by diet, behavior, morphology, and other characteristics. Among these, southern resident and transient killer whales commonly are found in Puget Sound. Northern residents and offshore killer whales rarely enter Puget Sound (Wiles 2004, Kriete 2007), and therefore are not described in detail here.
Harbor seal numbers were severely reduced in Puget Sound during the first half of the twentieth century by a state-financed population control program. This bounty program ceased in 1960, and in 1972, harbor seals became protected under the federal Marine Mammal Protection Act and by Washington State.
The Puget Sound region has the highest densities of bald eagles in Washington. Breeding pairs initiate nesting activities in January or February.
More than 70 bird species regularly utilize Puget Sound during some or all stages of their life histories, but only a portion of these are actively being investigated.
Fish in the family Salmonidae (salmon, trout, and charr) play potentially integral roles in the upland freshwater, nearshore and pelagic marine ecosystems and food webs of Puget Sound.
Approximately 28 species of rockfish are reported from Puget Sound, spanning a range of life-history types, habitats, and ecological niches.
Bentho-pelagic fish utilize both bottom habitats and shallower portions of the water column, often feeding in shallow water at night and moving to deeper water to form schools during the day.
Recent worldwide increases in the abundance of some jellyfish have been associated with human-caused disturbances to the environment such as eutrophication, overfishing and climate warming.
Dungeness crabs are an important resource in Puget Sound for recreational, commercial, and tribal fisheries. They utilize a variety of habitats over the course of their lives, and are vulnerable to shifts in ocean temperature and water quality.
Pinto abalone are the only abalone species found in Washington State.
Many types of bivalves, both native and non-native, flourish in Puget Sound. These species are a crucial part of the Puget Sound ecosystem and are also important for commercial fisheries.
GIANT PACIFIC OCTOPUS (Enteroctopus dofleini) is the largest species of octopus in the world. It is found in the northern Pacific Ocean from the northwest coast of the continental United States to Japan, including Puget Sound.
Forage fish occupy every marine and estuarine nearshore habitat in Washington, and much of the intertidal and shallow subtidal areas of the Puget Sound Basin are used by these species for spawning habitat.
The Encyclopedia of Puget Sound, in cooperation with the USGS, has developed a list of terrestrial vertebrates occurring within the Puget Sound basin.
