Absurd Creatures: The Caterpillar That Freaks Out if You Yell at It

In the rainforests of Peru there lurks a caterpillar that doesn’t appreciate people yelling at it. Do so, as field biologist Aaron Pomerantz did earlier this year, and in a flash it unfurls bizarre tentacles. But why? And how? This week’s episode of Absurd Creatures is here to explain.

Also, I’m happy to hear from you with suggestions on what to cover next. If it’s weird and we can find footage of it, it’s fair game. You can get me at matthew_simon@wired.com or on Twitter at @mrMattSimon. And check out the Absurd Creature of the Week column right here. Read more.
