Since this thread has veered way off course, I will contiue its off topic trajectory. Halichoeresbivittatus is a small fish in the wrasse family commonly found in the Gulf of Mexico and western Atlantic. The common name for Halichoeresbivittatus is slippery dick. One of the interesting things about the slippery dick is that they are hermaphrodites. The slippery dick starts out life as a female and later in life it changes its sex to male. And now you know the rest of the story.
