I see your “snakes have two penises” and raise you “kangaroos have THREE vaginas”.

Hemipenes (and penis/intermittent organs) are really diverse in terms of size and shape. A lot of lizards and snakes have little nodules and barbs that vary from species to species. Not sure what the ornaments do, but it's interesting. Also interesting is that having two (i.e. one on each side) potentially means that there's a handedness in terms of the preferred side used for mating.

Other fun facts about penises and other intermittent organs: cats and other felids have barbed penises that force ovulation in the female. Tangentially related are the pseudo penises of female hyenas.

More fun facts: damselfly males have intermittent organs that are spoon shaped so they scrape out the sperm of rival males.

Respond 'cock facts' to learn more about penises and intermittent organs.

Respond 'stop' if you don't want to learn cool shit.

Not just snakes, most reptiles.

Also common in other branches of the evolutionary tree as well, as in most sharks.

I love this twist on that: "Did you know that on average, snakes have one penis. Now think about it carefully"

Don’t echidnas have 4?

and here I was sitting on my duck corkscrew penis knowledge like I was a well educated soul....

Do they use both at the same time? For pissing? For intercourse? For the third thing? Does a snake have a favored penis? Are they corkscrew or some other unusual shape?

I never thought I'd have so many questions (read, more than 1) about snake penis.

All the wild rabbits around where we live have two as well. Happens apparently.

thanks for the info, ill definitely use it a lot

And so do sharks.

E621 and it's consequences, at least for me
