Flourescence in squid/octopus

[kalim1998]

Just something i am wondering about.

I just posted some information about flourescence in a mantis shrimp:
http://www.blueboard.com/mantis
http://www.blueboard.com/mantis/pics/caldwell_shining.htm

in a linked article someone noted that that this was the first case where a link between fluorescence and communication was found. Stomatopods have the most complex eyes in nature, and the hypothesis is that it uses this as a way to signal to other mantis shrimps.

However, i remember reading about squids (or octopus?) using flourescence for communication as well...or am i mistaken?

Just something to look at.

This is a subject that I am sorely ignorant of; I'm afraid I cannot comment, sorry. Some information can certainly be found here though : http://www.tonmo.com/science/public/deepseacephs.php

There will be others in the cephalopod community that know orders of magnitude more than I do, so I'll just have ti sit this out and hope someone responds.

There is indeed a link, but not though florescence.
Drs. Mather, Wood, Roper, and several others, as well as us non-Doctor types, have been studying Sepioteuthis Sepioidea (Caribbean Reef Squid) in the wild off the coast of Bonaire for nearly 7 years now, and there is some very strong evidence suggesting that they do indeed use their color changing ability for mating and territorial communications.

If you have any specific questions, feel free to let me know.

ahhhh...yep, i must have been thinking of color changes, not fluorescence...thanks for all the replies!
