Orca whales are one of 29 species of marine mammals in the sanctuary.
Olympic Coast National Marine Sanctuary includes 3,188 square miles of marine waters off the
rugged Olympic Peninsula coastline. The sanctuary extends 25 to 50 miles seaward, covering much of
the continental shelf and several major submarine canyons. The sanctuary protects a productive
upwelling zone - home to marine mammals and seabirds. Along its shores are thriving kelp and
intertidal communities, teeming with fishes and other sea life. In the darkness of the seafloor,
scattered communities of deep sea coral and sponges form habitats for fish and other important
In addition to important ecological resources, the sanctuary has a rich cultural and historical
legacy. Over two hundred shipwrecks are documented here. In addition, the vibrant contemporary
communities of the Makah Tribe, Quileute Tribe, Hoh Tribe, and Quinault Nation have forged
inseparable ties to the ocean environment, maintaining traditions of the past while they navigate
the challenges of the present.
Brilliant Paragorgia corals and feather-like crinoids grace the seafloor.
