That is a common developmental abnormality in a carrot. Maybe one out of 10 or 15 carrots has some kind of split. The juicy carrots that people prefer, are probably more disposed to splitting than drier-tasting cultivars. Lengthwise splits due to excessive water uptake combined with genetic predisposition to devloping splits, results in the skin cracking and the carrot splitting anywhere from 1/4 inch to 4 or 5 inches or more. Sometimes just about the whole length of the carrot. If the amount of water in the soil then goes down, and if the carrot continues to grow, the split will skin over, and look much like the photo. They are quite common, and they all look, more or less, like a "vagina." There does appear to be an "eversion" process in a carrot that occurs subsequent to it splitting, that resembles the way the labia majoris evert, developmentally, in a human vagina.<br><br><br><br>
With enough time and experimentation, I'd bet that I could create cultured carrot-vaginas, much the way the producers of cultured pearls create cultured pearls. It would be a matter of selected predisposed cultivars, over-watering, then cutting down on the water, then going through about 1000 carrots to select about 100 prospects, where there were splits and subsequent eversions, then selecting the 15 or 20 of those that look most vagina-like. I don't know about the little clitoris (are there big clitori?) at the top (actually it's the bottom) of this carrot-vagina. That would be a bit of luck that might take awhile. Carrot forking with clitoris-sized forks is quite common. Having the fork occur exactly at the top of the split, would be less likely. The likelyhood could be increased if we can find some way of controlling where a split occurs, perhaps by lightly scoring an overwatered carrot -- I think that when cultured pearls are produced, little pieces of sand or something are intentionally placed exactly where the oyster farmer wants the pearl to occur.
