Interesting to find three of these (each individual pictured) during a low-tide walk. Found under the north-end Vashon Ferry Dock.

Found under edge of dock on eight-inch long tubular substrate hanging out from dock.

Found during dock-fouling excursion. Many on knob-tipped hydroid.

Maybe only as big as a grain of rice. Will add more photos from video stills and a video link once I can.

Foot-side up on some sea cucumbers — I think two individuals? IDed by @jensseattle based on others seen nearby.

Tons of little sea cucumbers nestled amongst the mussels at a dock.

Blurry photo from a video. Lots of little hammerhead dotos enjoying the hydroids growing on a dock.
