Functional Biology of Sea Anemones

[BonsaiNut]

I feel like I'm back in college -- happy to be here but COMPLETELY confused. The book is very slow reading -- it's good bedtime reading. I either learn something or I fall asleep. Win-win in my book.

Coolest part... they KNOW anemones can sense light - that they can respond to light stimuli and some species will respond quickly and strongly to a shadow passing over them... but no one knows how They have no eyes, no central nervous system, and no brain.

So a cloud simulation on the lights will have an effect on them.

I will say this... in French Polynesia when the sun sets, all the H. magnifica close up and puff up like big puff balls. After an hour or so, they open back up (so they are more or less open at night). I guess I could understand if they were responding to a change in their zooxanthellae... but they would do this even on a cloudy day.

Nice... You keep mentioning areas that I want to go. You need to stop before I stop frequenting reefing forums and start frequenting south pacific forums.

That would be a cool thing to see in time lapse... a gaggle of them all together.
