A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. These worms are up to 5 cm in length and bear a crown of lavender tentacles. Differences in worm tube height were detected, with a significant interaction term (p = 0.018) indicating that worms outplanted from high to low intertidal grew significantly longer tubes compared to those that remained in the high intertidal. Tube worms rely on the bacteria in their enviornment to oxidize hydrogen sulfide, using dissolved oxygen in the water as an electron acceptor.

The common name "giant tube worm" is however also applied to the largest living species of shipworm, Kuphus polythalamia , which despite the name "worm" is a bivalve mollusk, rather than an annelid.

Purple Star or Ochre Star (Pisaster ochraceus) Purple or Ochre Stars are one of the most common sea stars found in the intertidal zones and a major predator. When under water their feathery gills emerge to strain plankton from the … Creatures in this area can grow to larger sizes because there is more energy in the localized ecosystem and because marine vegetation can grow to much greater sizes than in the other three intertidal subregions due to the better water coverage: the water is shallow enough to allow plenty of light to And speaking of feeding, I should mention that Phragmatopoma is a filter feeder.
