Fun with Clownfish

 Clownfish are hermaphroditic - they are all born as males, and have the ability to step up in class and become female.  Clownfish schools are led by a large dominant female. And then if she dies, the dominant male in the school will change over and become the dominant female, and then a younger male takes up the mantle and becomes the dominant male.

But he knows his days of wearing the pants, so to speak, are numbered.

Holiday dinners must really be fun with these fish!
