Dolphin vagina

"There's an image of a female dolphin's genitalia at http://img2.moonbuggy.org/imgstore/dolphin-vagina.jpg (not technically porn, but let's play it safe here). It's hard to see too much detail from the picture, but it doesn't look all that different from a human vulva at first glance. FYI, searching for "dolphin vagina" actually doesn't turn up that much porn, but I think I have to clear my history anyway. "
