Video of a snail being taken over by a parasitic worm looks like a looping psychedelic GIF

Computational biologist Mike Inouye posted this video to Twitter, saying, "This zombie snail. A parasitic worm Leucochloridium has taken over its motor functions and eye stalks, making them into caterpillar mimics so birds will eat them. The worm can then reproduce in the bird's GI tract, eventually transmitting via its faeces."
