Sea Cucumber SEX Videos!!! aka if the sea cucumber is SO sexy how come it doesn't get the LOVE?

Even though its still cold out..Spring is right around the corner! and with my computer still in the shop... I thought it would be a good week to continue on with last week's Echinoderm sex video theme-only making it one step MORE disturbing!


Let's watch sea cucumbers spawn!

What you're seeing here is reproductive material being broadcast into the water. If you have kind of a dirty mind- you MIGHT think that the effluvia being emitted is sperm, but its actually NOT ..
What you're seeing could be male or female-sperm and eggs (as with the sea urchins, only they know for sure!)
. The sperm and/or egg then proceed to find other eggs/sperm to fertilize. Not an easy task in the big ocean!

What's curious is the behavior of the various sea cucumber species.. I'm not sure if all of them do..but many apparently sea cucumbers rear themselves up into the water as shown above and below. I'm not sure why they do this-but it seems that it likely has to do with the more efficient dispersion of their reproductive material into the water column.

Let the geyser powered, priapic Freudian Echinoderm nightmares commence!!

(this one is kind of a cheat since I've used it before.. but its excellent)

spawning in this one starts at 1:02-after that its mostly fish...

This one's kind of dark...

OK, yet again I find the musical accompaniment in that next to last video creepily inappropriate. The vids are cool, though!

I wonder if this phenomenon is similar to what we find in the alpine here in Colorado: the wind(current) is much stronger a few inches above the ground than it is right next to the ground. In the alpine, this is bad if you are a plant because it dries you out very quickly, so all the little Alpine plants do their darndest to pack every bit of their lives into the no-fly-zone within a few inches of the ground.

If you were looking to broadcast gametes, however, perhaps lifting your derriere into the faster-moving water might be a better way to go . . .

This blog is absolutely delightful. Thank you for taking the trouble to post this great information about echinoderms -- I've already tweeted about two of your videos and will doubtless be promoting many more of them. I look forward to many happy hours poking around in your archives!

thanks for the kind words! If you have any specific topics you'd like to know about-lmk..I'm always open to inspiration!
