Does anyone on Coral-List have observations of barrel sponge spawning?  We have been recording observations around the Florida Keys, and are interested in collecting more Xestospongia muta spawning observations in the hopes of summarizing some of their spawning behavior.

I appreciate any info you can provide regarding the location, date/time, temperature, depth, and perhaps if you recall whether males were releasing sperm (smoking), females had eggs (looks like foam), eggs were being released into water column (drifting foam), or whether there was a gelatinous mass around the sponge (embryos).

If you haven't seen these amazing sponges spawn, check out our video: https://www.youtube.com/watch?v=5zWrSmpkV_I

Thank you!
