I once had to write a mini story in grade 5 and the characters had to be animals. So I made the story about an Anglerfish. And my teacher was like...fish aren't animals. And I was like...okay. But inside I was like...are you freaking stupid, fish are animals, if they weren't they would either be a plant or a fungus, so tell me what are they?!
Also, you know you're a marine enthusiast when you hear the term "Argonauts" you don't think of the football team, you think of the cephalopod
