Food Web

Puget Sound hosts more than 100 species of seabirds, 200 species of fish, 15 marine mammal species, hundreds of plant species, and thousands of invertebrate species. These species do not exist in isolation, but rather interact with each other in a variety of ways: they eat and are eaten by each other; they serve as vectors of disease or toxins; they are parasitic; and they compete with each other

Habitats of the Puget Sound watershed

"Habitat" describes the physical and biological conditions that support a species or species assemblage and refers to conditions that exist at many scales. An oyster shell provides habitat for some algae and invertebrates, whereas cubic miles of sunlit water in Puget Sound comprise the habitat for many planktonic species.

Herbivores and detritivores in Puget Sound

Many consumer organisms in Puget Sound are both herbivores and detritivores. Zooplankton and benthic invertebrates that are scavengers, herbivores, or detritivores are considered jointly in this article. Some of these organisms can be predatory as well. Hundreds of invertebrates and fish species have a planktonic larval stage that eats plants and occupies the nearshore and offshore pelagic waters

Mid-level consumers in Puget Sound

A variety of animals, including invertebrates, fish, mammals, and birds, consume the suspension-feeders, filter-feeders, grazers, and detritivores that serve as a link between the primary producers and detrital pathways and the upper levels of the food web.

Top-level predators in Puget Sound

Fishes, birds, and mammals (including humans) serve as top-level carnivores in the Puget Sound ecosystem. With the exception of humans, these organisms have a diet that consists almost entirely of fish or other vertebrates.

Less rain and sun and colder temperatures. Conditions are challenging for crew and instruments. Large jelly fish patches in Inlets: Budd, Sinclair, and Case. Central Sound algae bloom continues as temperatures fall and oxygen is still decreasing at places. Freshwater water moves into Central Sound.

Morning fog shows that fall is here! Warm afternoons with colder nights make cooler-than-normal conditions. Temperatures decrease and blooms fade as the summer growing season comes to an end. Brown-red blooms still in Carr Inlet and Budd Inlet. Green bloom near Squaxin Island.
