Field Notes

Description:

White, mesh-looking growth along side red algae. Was pliable and smooth like the algae. Bryozoan "are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres (0.020 in) long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia." - Wikipedia

Habitat:

Tidepools in La Jolla along side red algae.

Notes:

"Most marine species live in tropical waters, but a few occur in oceanic trenches, and others are found in polar waters. One class lives only in a variety of freshwater environments, and a few members of a mostly marine class prefer brackish water. Over 4,000 living species are known. One genus is solitary and the rest colonial. Individuals in bryozoan (ectoproct) colonies are called zooids, since they are not fully independent animals. All colonies contain autozooids, which are responsible for feeding and excretion. Bryozoans, phoronids and brachiopods strain food out of the water by means of a lophophore, a "crown" of hollow tentacles. Bryozoans form colonies consisting of clones called zooids that are typically about 0.5 millimetres (0.020 in) long. Predators of marine bryozoans include nudibranchs (sea slugs), fish, sea urchins, pycnogonids, crustaceans, mites and starfish." - Wikipedia

I know, right. Of course, they probably haven't read the published works. And, they'd rather use the bryozoans as scape goats for things like pesticide and herbicide runoff etc affecting the habitat. Oh, well, not that the state ever uses such things!
Hmmm, that's interesting. I'd be interested to hear NY State DEC's argument on this to compare with published works.
Dr. Wood said that they clean the water, and are harmless. I didn't weed through the pages of writings yet, but apparently the NY State DEC thinks that bryozoans are detrimental to pond life. I know for a fact they didn't harm any of the fish, frogs, or salamander life in my pond.
It really is! I'm quite intrigued by these organisms now that I know they exist :)
Well Cindy, I think you can risk that "wannabee" word from your profile... :-)
Thank you :) You're soooo close! I really did think you'd make it before me with all you incredible spottings! 2001 sounds like a great goal. It may take me longer than 6 months for the second 1,000 :)
So, Cindy, you reached 1001spots, huh? Congratulations, you have a wonderful collection. Keep on, and lets go for 2001!!!
Thank you so much for the information! I really appreciate it. I hope to get better images of other Bryozoan the next time I return to the tidepools.
Hi Cindy, I'm a biologist with the Smithsonian. This is most definitely a bryozoan, probably from the family Membraniporidae or Electridae. Without a close up it's hard to say which group. They are very common, especially growing on seaweeds.
I've uploaded a cropped image of the spotting. Any Bryozoan experts on?
Could it be this? http://nathistoc.bio.uci.edu/Ectoprocta/Bryozoan.htm
