Help to ID (Blinking green light at night)

[Wonder]

Manage to took a vedio and picture as well. My hand was moving while taking vedio (very dark). After i try to take photo with flashes, the blink just go away. Any Idea what is this ?

My guess is it's the arm to a brittle star.

I love this website for Ophiuroid info, in the intro you can see the bioluminescence. Watch the intro for the part that says, "...and glow": Ophiuroid's Home Page.

Here is a quote from the website above: Ophiuroid Tabloids.

The brittle star Amphipholis squamata may help deter predators in an interesting way: when a crab grabs part of the ophiuroid's arm, it breaks off, but keeps wiggling and flashes light (bioluminescence- like in fireflies). The brittle star then gets away while the crab grapples with this unusual meal! (Go to link under "related stories" to see a cool photo and information about this research!)

Here is another link from the same website: Ophiuroid Luminescence for Studying Microevolution

Thanks all for the reply.

NaH2O,
Appreciate your detail link. Will read it up. It's really cool. Marine life is forever that interesting with new things discover every now and then:exclaim: Even when i make sure everything i introduce into my tank is inspected, i still get worms and crabs UFWO ?

Nikki hooked you up with great info. It's with great sadness to announce that Susan (who provided that info) has given up her research on ophiuroids. Thankfully, she still pays to keep her prior research up.

OMG! Curt, I didn't know that! I'm glad she is still maintaining her website. Too much valuable info to be forgotten.

we see that bioluminescence sometimes out in the ocean during certain times of the year.. it is pretty neat to go watch at night!!!
