Cuttlefish change their stripes to look male on one side, female on the other
Talk about showing your feminine side. On one flank, a courting male cuttlefish looks like a normal male of his species, with tigerlike stripes extending horizontally down his body. But on the other, he resembles a female, displaying marbled browns and whites. He needs the male pattern to attract the female, while the female motif keeps competing males from fighting him.
