Description

Photos were captured by Robert Landy (dive buddy of mine, not on inat). These tube anemones seem different than what we've historically called "Pachycerianthus borealis" in my area though perhaps this is just informed by the specific attributes of the dive site. Generally I'll find similar looking individuals, burrowed in mud/muddy sand. The top of the tube is almost always flush with the substrate and I rarely observe the tentacle diameter any larger than ≈7cm (https://www.inaturalist.org/observations/58284007) .

By comparison, these are monsters. There was a small group in the same spot for several years. Unlike my typical "P. borealis" observations the tubes of these would extend considerably above the substrate, maybe ≈25cm and the tentacles/oral disc much larger, ≈15cm.

These were observed in fine, silty mud, 43m depth - very difficult to get to during the course of a recreational dive. They were burrowed a long swim from the mooring line and you may only have a couple moments to observe before having to turn back. The few times I've seen these years ago, I was quite loopy from the depth so take that into consideration when assessing my estimated size of the organism.

I'm pretty sure these are red hake though I might be incorrect. It's hard to see where the mouth terminates relative to eye, but the pelvic fin ray seems to terminate a little after anterior start of anal fin. Mottled brownish (with dive lights). These were schooling by the thousands at the Patriot shipwreck ≈30m depth. A couple sculpin in the mix too.

Description

The Bangiaceae - Porphyra, Pyropia, Nori, 海苔 and Laver are more or less, the same thing. Often brownish but can be pink, green, red, olive, purple or in-between colours. They come in different forms (shapes) but are usually one cell thick. like clingfilm or Saran food wrap. It is often difficult to photograph definitively. Best collected and laid on a white board or light table and teased out with a fine watercolour brush. Some species are best photographed in water, say in a transparent tub.
It is notoriously difficult to get to species and almost always requires microscopic examination of the simple cell structure. It is unwise to offer, or agree to, a species unless accompanied by a micrograph.
It is widely eaten or used in food products. Washed and crisp-dried it can be sprinkled into sea-food dishes or, when dampened, used as a wrap.
It occurs across the oceanic globe but is absent, or not well recorded, in some specific areas https://www.gbif.org/species/2653483
and https://www.gbif.org/species/4908866
Clearly then, the two genera (Porphyra & Pyropia), overlap their records, which seem, on the face of it interchangeable.
This is a cautionary tale then, for those who post either Genus, without supporting evidence, preferably cell micrographs, then the very best that can be proposed may be the FAMILY Bangiaceae.

Sea Felt may best be identified from its overall morphology. It appears most often as a brown cloud attached to Fucus but can occur washed in unattached.
It is incredibly fine close-to and cannot be identified with just close up photos. It is JUST possible to see, via a x10 glass, the woven filaments which appear to make very fine 'ropes' - if you can see those, then you're on a good bet - Picture 11. Beyond that you will have to spend quite a time at the microscope to get photos of the minute features that ID it positively - the general cell structure and the specific presence of intercalary sporangia, mid-length of those microscopic filaments will thus conform the ID - Picture 12.
In short BOTH views are normally required for ID, one general view of its overall morphology and one of the 'rope' structure or the mid-filament reproductive cells.

Might be wishful thinking narrowing down to genus. I did my best to get clear images from every perspective I could. 2.5 meters deep, Likely close to 2.5 cm in length. This was one of the most difficult things I've ever photographed underwater. It was so fast and unpredictable, held many positions in the water column.
