File this one under "just when I thought I'd seen everything." After writing last week about how scientific research has shown women respond to visual stimulation (like say, pictures of penises), I came across the following two examples of penises in the wild. First and foremost, the discovery of the Cambrian era Herpetogaster collinsi. This little gem of an extinct creature not only looks like a penis, but it also has the most interesting fronds attached ton the end. With appendages like that, it makes one wonder why it died out. Certainly not from an inability to perform in bed. The second creature is a current-day wonder known as the geoduck (pronounced gooey-duck). While the Herpetogaster collinsi looks like a kinky little sex toy, the geoduck reminds me more of porn star Ron Jeremy. Of course, if neither of the above instances of natural penises in the wild tickle your fancy, take a look at a few stone beauties in the Haeshindang Folk Village, also known as the Penis Park in South Korea. Granted, this last link is more cultural than scientific, but still, you have to admit these penises are pretty wild. So that's your bit of Science of Sex for this week! Enjoy.
