“Hey, everyone likes spiders, right?”

“Well, uh…”

“Of course they do. Spiders are cute, and they keep the insect population under control.”

“They sure do, evolution.”

“Anyway, I was thinking of making something similar, but for the ocean. Like a… sea spider.”

“A sea spider.”

“Mmm hmm. Only it’ll barely need a body, because I’m going to stuff most of its organs and its digestive tract down its legs. And instead of eating insects, it’ll stick its long proboscis into sea anemones and suck their insides out. What do you think?”

“Well…”

“I think everybody’s going to love it.”

“Yes, evolution, I’m sure.”
