Ever have one of those days where you’re supposed to concentrate on making orchids but just can’t stop thinking about monkeys? Because evolution does. All the time. Like, it thinks about monkeys a lot. That’s normal, right?

“Hey, remember the gastric brooding frog?”

“Which one was that again?”

“You know, the cute little one where I cleverly arranged for it to incubate its eggs inside its stomach and then regurgitate the hatchlings through its mouth.”

“Ugh, right. What is it with you and frog hatching, evolution? Anyway, didn’t the baby-vomiting one go extinct?”

“Yeah, it did. But now the humans are trying to resurrect it!”

“What? Why?”

“Because everything deserves a second chance.”

“Really? Everything?”

“Man, I knew I was keeping those big-brained weirdos around for something.”

“Oh, man. I just had the best idea.”

“Let’s hear it, evolution.”

“You know how everything is better deep-fried?”

“Wait, what?”

“That other batfish was nothing. Look: pancake batfish. Pancake batfish! I’m a genius.”

“God, you’re weird.”

There’s no particular explanation for this nudibranch. Sometimes evolution is just having a good day, okay? Just… a really good day. For once. Please don’t screw this up with a mass extinction or anything.

Sometimes evolution produces ridiculous creatures like the sarcastic fringehead just to watch them fight. Immature? Possibly. But you try keeping yourself amused for 3.8 billion years.
