From Nature news today, NZ researchers have discovered you can sex dolphins by looking at their fins. Males have more scar tissue and females have more scabs (phrased at patchy skin lesions in the news article).
Show me your fin bigboy!
It's not the size its the scarring!
It's been awhile since I had a science blog. this might be stretching it, but godamnit I'm taking it!!
