The Cambrian had a bunch of strange creatures like this. There was the Opabinia, which had five eyes and a mouth on an arm. And there was the Anomalocaris, which is kinda similar to the new one they discovered (at least from the perspective of a non-scientist just looking at the artists’ renditions), but with only two eyes and an order of magnitude bigger.

I bet it tasted like shrimp.

Simpsons did it first
