When it comes to the Finding Nemo franchise, Pixar really seemed to do it's research. Their fish science went the distance to make the movie feel as authentically under the sea as possible - mostly. You see, clownfish are very cool creatures, very RESOURCEFUL creatures. With Nemo's mom removed from the picture due to natural predators, Marlin stepped up to solo parent. One point for good dads! Except... maybe not? You see, we need to talk about Marlin.
