4/16/2002: Largest duck penis

[Undertoad]

Now y'all know what I always say... IotD isn't for porn. It's for stuff that's mind-boggling or interesting or good images, etc.

Duck porn, however, is something else. According to the folks at Nature, what ya got there is the longest bird penis on record.

The unit, which measures about 20cm, is the pride of the "Argentine Lake Duck", but science does not yet know how the bird uses it, exactly. From the article, "...the drake's penis has a brush-like tip, which they say the males probably use to scrub the sperm of previous mates from the female’s oviduct." Gives a whole new meaning to the word "tool". They're not trying to be clean about it; males are competing against one another for procreation rights, and the slutty female ducks apparently give it up easy.
