Really? :beerchug: Do I know you? :new_smili

I can't find it in my books either. Is it okay if I download it & send it to a friend who specializes in flatworms?

Sounds like a good fit!

Florida, huh? The two big swimming Aplysia species from that area are A. morio and A. brasiliana. In a coincidence someone else asked about them just a couple of days ago. More info & links here: http://www.scubaboard.com/showthread.php?t=139824

Chad, I'm having problems with yours. My first guess is some sort of arminid out cruising for a tasty sea pen but I'm not sure. Did you see any sign of gills? Are they retracted? Trinigordo, you've got two different animals. I don't know the first one - not enough detail but the second is...

As Rick said, all of those would be very helpful to confirm ids. I'm guessing from your location that these are probably Indo-Pacific. That would make your first critter one of the big horse conchs, maybe Pleuroploca. The second is a lamellariid snail identified only as Coriocella sp. in...

That's definitely a puffer (also called toby) in the genus Arothron, maybe A. caeruleopunctatus (blue-spotted) or A. mappa (map toby).

I'm with Isurus & Mark on #1 & #3 but on #2 I'd go with Phidiana indica. So how come you don't post any worms?

Did you look at all the links posted under Aplysia morio on the Sea Slug Forum? You can view them all at once by clicking on the command at the bottom of the page: "show factsheet & all related messages". The othe big species in Florida is Aplysia brasiliana. Take a look at the SSF page - do...

Hey, stop poking that slug! Only biologists get to do that! :D Where is it from? If it's west coast & central California south then it would be Aplysia vaccaria. See http://slugsite.us/bow/nudwk215.htm From Florida then Aplysia morio, see http://seaslugforum.net/factsheet.cfm?base=aplymori

Yes, something was broadcast spawning. It could have been worms, clams, anemones, etc - any one of a number of different species that reproduce by shooting their eggs & sperm into the water. Sperm is usually white, eggs are usually colored.

Oodles, you say? Odds bodkins, Archman, oodles you can have by reading the article..... I first learned about this because I photographed a similar Santia cloaked in cyanobacteria from the BVI (http://www.nhm.org/guana/bvi-invt/bvi-surv/images/pera-i04/h0705ax.htm) & was contacted by Niels...

And you're defending worms? When did hell freeze over? :D

Thanks for posting this Vie. I've been sending it off to my crustie friends for their admiration.

The enlarged version of your image wouldn't download so I can't see the animals clearly. Still, I'm pretty sure they're small isopod crustaceans called Santia or something similar. These critters are very neat -- the orange covering is actually cyanobacteria which grows on their bodies. The...

I think Vie's nailed it!

Leave the id as polychaete egg mass. There are a number of species in different families that make similar egg masses so I wouldn't be too hasty to assign them to Arenicola. Highest species diversity? While I always boast about the superiority of worms to other groups this is one claim that...

THe first is a problem. As far as I can tell the main visual difference between quadricolor & magnifica is the width of the marginal white band and there's so much variation in the images on Sea Slug Forum that I'm kinda baffled. But at least it's between those two...

Nice to see so much talk about a worm for once! Just for the record, I do think it's Hermodice carunculata, the bearded fireworm. Cheerio!

Very likely. It's a good idea to stay away from anything jellyish!
