The Puget Sound King Crab (Lopholithodes mandtii) is quite colorful.
Giant Plumose Anemone (Metridium farcimen) with mostly retracted feeding tentacles.
With a length of 40 meters, the Giant Siphonophore (Praya) is one of the Earth's largest animals. This image shows a section of one that I located while scuba diving in in Barkley Sound, British Columbia, Canada.
