Rock Scallop
Round, thick shell. One of the largest scallops in the world. An orange mantle with sensory tentacles and blue eyes fringes the shell. Permanently attached to substrate, does not detach and swim around.
Northern Abalone
Shell is mottled greenish and reddish brown with areas of white or blue. Radial ridges span over a spiral sculpture. Only abalone in Pacific Northwest.
Gumboot Chiton
Oval-elongated. Yellow underside with large, broad foot.
Oregon Triton

Leafy Hornmouth
Large “tooth” projects from the aperture, used to force open shells of prey.
Giant Pacific Octopus
Reddish brown coloration can vary with background. 8 suction cup-filled arms are 3-5 times the length of the body. Look for a pile of discarded shells to find the opening to a den.

White-lined Dirona
Flattened and pointed gills. Background color is a translucent grayish white, salmon, or purple.
Opalescent Nudibranch
