Hydroid formation covering a hermit crab.
Tidepool Tim says, “These hydroids grow quickly can cover everything in a tidepool by summers end - rocks, seaweeds, shells, snails, crabs, etc. They are easiest to collect on kelp plants and mooring lines. We like to watch bushy-backed nudibrancs eat them as they graze across the surface of the kelp plants.”
