Gray Encrusting Compound Tunicate
Scientific Name:Â Diplosoma listerianum
This is a common encrusting compound tunicate that is commonly found along docks in the Pacific Northwest. Similar to other tunicates it grows on rocks, barnacles, bivalves, as well as the exoskeleton of a number of crab species. Though it may appear like a gray goo covering kelp that is growing along docks, it can be quite beautiful when viewed under a dissecting microscope.
