I've really got no clue what I'm looking at here, does anybody have any ideas? Appears to be some red algae, but I'm more interested in that dense yellowish hairy stuff growing on it, which I don't imagine is part of the algae itself. What is that? Found growing in a shallow tidepool this weekend.

+Darlene Winely Thanks Darlene! Glad you like it - shooting through the water is pretty tricky for me to get right.
Hey Chris
Looks like a green algae is growing on the red algae.
I'm on a cellphone now, so I'll take a closer look when i'm back at my computer 
Love the oxygen bubbles trapped among them.
+Hudson Ansley Thanks!
+Kjetil Greger Pedersen I Think you might be on to something, thanks Kjetil. I've photographed algae growing on algae before, but usually its the opposite, with reds growing on greens.
+Rajini Rao I seem to get air bubbles a lot in my algae photos! Sometimes they can be distractingly numerous, but a few here and there doesn't hurt :)
btw- green and red marine algae are also known as seaweed ;-)
oooh looks like the algae are borrowing a page from the lichen playbook.

how do you take underwater pictures without getting surface reflections?
+Wesley Yeoh It's all about the angle... if I shoot straight on the flash bounces off the water and I get a solid white image, if I angle it just right I can avoid that... basically just a lot of trial and error.
+Chris Mallory have you ever tried airtight bagging a flash and remote firing it underwater?
Those storage bags you can suck the air out of with a vacuum cleaner work well - you get peace of mind that its sealed, and as a bonus the bag loses bouyancy.
Nice shot though, really interesting perspective.
Lovely natural "high sepia"... I really like how you captured this sea flower (that's what it looks like to me)! :)
I've just had a look at my computer now.. And now I'm sure it is some green algae. I can't name the species, but you should be able to at least identify the family by narrowing your search down to area and habitat.
I think that there are quite a few algae that are epiphytic on seagrasses, that might be a good place to start - maybe some are not fussy about which plants they grow on?
