The Mysterious Deep Sea Creature

In 1950, scientists discovered a strange creature living in the depths of the ocean. For the last six decades, scientists have been trying to figure out the origins of the animal, Xenoturbella, which looks a bit like an old purple sock, and has no eyes, gills or brain. Now, researchers believe they’ve figured out where this alien of the deep falls in the hierarchy of the animal kingdom. Credit:MentalFloss
