Some of you may recall a movie of mating slugs I mentioned before…now here’s a site with photos of the act.
In case you’re baffled, the strange translucent blue sheets hanging down are the interwined penises of the two slugs. Don’t they make a beautiful couple?
(Thanks, Craig Clarke! Does your mother know you browse the web for molluscan porn?)
Well. Those are rather, ummm, impressive.
And I’m not at all sure I’ll ever get the image out of my mind.
As the saying goes, there’s show-ers and then there’s grow-ers.
Now I know which one slugs are.
This post reminded me of this comic.
Granted they’re snails instead of slugs, but the humor remains the same.
Seeing this reminds me that the BBC’s Life in the Undergrowth is out on DVD.
It’s like something from outer space.
That reminds me of a really, really bad date I once went on…
I just scrolled down to the customer reviews for Life in the Undergrowth, and I see that there is one single one-star review among the glowing five-star reviews. This one person was “very disappointed” with the DVDs because “They were FULL of evolution”.
Argh.
I actually stumbled on that by accident, but my mom knows I enjoy looking for molluscs. They have nice big ones where I live. I have a 14 inch Lighning Whelk shell on my porch table.
PZ-
Now, I love a big transluscent blue penis as much as the next guy (probably more so), but as I understand it, the organ coming out these critters heads exchanges both eggs and sperm.
So the term penis isn’t quite right , is it?
Wait… the entire blue glob is their penes? And they come out of their heads? I have no idea if I’m seeing that right. And is it still “mating” if they’re both male?
Hermaphrodites.
Some molluscs fence with their penes. Others shoot sperm darts into each other’s bodies. This is less ballistic and more balletic.
I’m moved to song:
A twisted young fellow named Wallace
Once had an affair with a mollusk,
But that’s not as odd
As the brachiopod
Who buggered an ostritch for solace.
I can’t believe that the obvious hasn’t already been stated.
Those slugs are hung!
As with most visuals of this sort, I can hear Bill Hicks commenting on this:
“You the guy buyin’ all the bobbin’ slimy slug-ass movies?”
“Nuh UH! It said ‘Pink Gastropods’! If it had said ‘Bobbin’ Slimy Slug-Ass’, I never woulda bought the m**********er!”
Ahh, so weird and pretty… once saw a slug in a neighbor’s yard that actually startled me, it was really big had these huge eye spots and.. and… well, it looked at me… shudder.
True, Jeb, yet somehow I don’t see the expression “hung like a slug” catching on much.
The earlier post about the slug movie us titled
They’re blue, and long, and prehensile, and beautiful!
Which prompted the comment:
Drop out the second “and” and it scans for the opening of The Girl from Ipanema.
Which got me going:
They’re blue and long, prehensile and beautiful,
They hang on stands of mucus so fanciful,
And when they twine, it feels so fine, they go ahhh…
Slick and wet and oh, so clingy,
I wish I had a pale blue thingy,
And when they twine, it feels so fine, they go ahhh…
Ooh, but I envy so madly,
How can I ever aspire to ….
Drat, do I do sex so badly,
I can watch, and can love what I see,
Slugs indeed do have more fun than me.
They’re blue and long, prehensile and beautiful,

They go ahhh …
Thank Owlmirror – the only hermaphrodites I know anything about the mating of is C. elegans, and from what I recall the more rare males can cross-mate with a hermaphrodite but otherwise the hermaphrodites self-fertilize internally.
Taking off of JonJB’s comment… so is the sac at the end gametes? And since they’re hermaphrodites they have both and are just randomly exchanging? I imagine that afterwards they suck it all back in and later lay eggs?
I’m surprised nobody made any “dickhead” jokes.
And that “shooting sperm darts into each other’s bodies” thing gives me an idea for a macromedia flash game.
According to this biology lab page (search for “Courtship and Mating”), they are exchanging sperm only. Apparantly, they do sometimes self-fertilize.
There’s a more detailed description of the Limax reproductive system as well.
There’s also this rather explicit description of the foreplay:
Whoa, kinky.

“Hermaphrodites.”
Oh, good. I was afraid maybe they were gay slugs.
That would have been really gross.
:-)
Like anyone’s gonna believe that when they figure out you’re related to me.
I don’t know if anyone will ever read this, and if they do, I imagine they’ll wish they had not, but:
When I was a kid (under 10, forget exactly), I was walking out my front porch and came across a couple of slugs just starting to hook-up. In retrospect (in human terms), I would say they’d had a good date, and at the end of the night one slug invited the other up for a “nightcap”, and they were just starting to make out on the couch.
A curious child, I sat down to watch them (fighting off the initial urge to salt them — cruel, yes, but a disturbingly fascinating thing to see, as well). They anchored their slime belay and descended over the precipice, entangling in that little swirl thing they do and extended their “appendages”. Lots of goo and oozing.
At the time, I was not entirely certain what they were doing, but I suppose I had a hunch.
It certainly made the later “birds and the bees” talk far more psychologically devastating for my parents…
Perhaps unrelated, but I’ve never been phased by any sexual fetishes as an adolescent or adult. I’m not into most of them, but still nothing really shocks you when your (internal) response is “well, that’s not as gross as the slugs”.
Great now there are two photos of spiral slug love on the web :) I made one too that is very similar to this (but even more defined I guess with a longer tail hanging down a straight wall) see it here:
