Jane, have you visited Pixalo.com ? Nice site to talk photographs and cameras.

BTW, love your pictures.

Okay I give up what is it?

The Portuguese Man O' War is often confused with a jellyfish, which is incorrect and may lead to improper treatment of stings, as the venom is different. A second sting may lead to an allergic reaction.
Great picture but they are very dangersous - even when dead.

What is that? Is that a jellyfish? Never seen one around in Belize

anyone remember like around sept 2000, small brown jellyfish filling the sea? tons of them?

There were two (dead) of them floating around at the Royal Palm on the 18th of June. I am assuming that they are the Portuguese Man-O-War as ScubaLdy said. I googled the name and there are several pictures that, I think, prove out her point.

I thought it was a jellyfish. If not, what is it?

Portuguese Man o' War Jellyfish! is what happens if you touch its tentacles.

repeating myself...

There were two of these, dead, in front of Jeanh's place (Coral Bay) the morning of June 23.
