Think of your favorite animal. Perhaps Harry Potter’s snowy owl comes to mind. Or, maybe the lion, king of the jungle? If we were to take our thought experiment under water, you might think of the massive whale shark, or the majestic sea turtle. Perhaps not. But I bet I can guess what wouldn’t come to mind. Freshwater fish rarely, if ever, have the celebrity status of these other animals. Yet, they can be just as fascinating.
