Cream with brown spots, found in collected mud under/between rocks. ID by Assoc Prof Keith Probert.
Under rock in sand at Botanical Beach, Juan de Fuca Provincial Park, BC
Lying exposed on wet sand in U shape. Dead.
Stumped by this one. Protruding from a small rock hole was what appeared to be a small head of orange broccoli - about 1/3" across. Branched, looked almost like a soft coral. When poked - because of course I had to poke it -, it sucked in the "broccoli" into the center in the manner of a peanut worm, and continued inverting itself until it felt safe (see second photo). The body of the worm was whitish with raised, pointed back dots.
Thought of orange sea cucumber (Cucumaria miniata), but their tentacles seem lacier and their bodies are orange, not white with black dots.
2 little worms found together under a rock in a tide pool. I didn't see any others during my fossicking.
The Sipuncula or Sipunculida (common names sipunculid worms or peanut worms) is a group containing 144-320 species (estimates vary) of bilaterally symmetrical, unsegmented marine worms. Traditionally considered a phylum, they might be a subgroup of phylum Annelida based on recent molecular work.
