Don't Eat Me: Caterpillar That Looks Like Snake's Head

May 29, 2014


This is a series of photographs from University of Pennsylvania biology professor Daniel Janzen of a species of caterpillar in Costa Rica (and other Central American countries) that has a realistic looking snake's head on its underside. Plus it will actually try to strike like a snake if you get too close. I don't know about you, but that would trick me if I were a predator. I'm going to eat you! Oh shit, no I'm not! Sorry Mr. Snake, I was just, uh, I was just reaching for these berries. Yeah, I was just going to eat these berries. "Those are poisonous." *swallowing handful* Finally.

Keep going for a couple more shots of the please do not back that ass up.




Thanks to Dio, who once bit the head off a viper because it was either him or the snake.

    How can you explain that, Evolutionists? (I know I'm getting myself into the sluice of trouble, but please, reply) :)

    ...I'm only giving you a response because you specifically asked for one.

    These aren't the first creatures to have asses (or other body areas) that look like they have another face. This creature is definitely more interesting in that it mimics a predator to ward off other predators, but there are lots of other critters that have spots mimicking an extra pair of eyes (fish, butterflies, etc). Wiki Eyespots for more information.

    Point being, this defense mechanism has been long in the making, & if anything, the fact that this cute caterpillar has developed something a little more advanced (though not as advanced as the Mimic Octopus) is proof of evolution doing its work.

    So snakes evolved first? But how can you be sure they did?

    This certain caterpillar just loved looking at snaked and decided to grown into one? How does that work.....?

    oh mother nature. you so crazy

  • dauntless

    if that's not an example of extreme evolution i don't know what is

    Said the exact thing in my head and then I saw you already commented this. Thief.

    He's evolved into a telepath.
