The Pink See-Through Fantasia Is a Dweller of the Deep Sea and You Can See Its Organs at Work

As if a jellyfish and a flamingo had a baby.

Despite its alluring name, the pink see-through fantasia is not a piece of seductive lingerie but a sea cucumber living about 1.5 miles (2,500 meters) deep in the Celebes Sea west of Borneo. Discovered only in 2007 by a team of marine biologists, this unique creature has evolved a survival tactic of bioluminescence to protect itself from predators.

Its transparent skin allows its mouth, anus, and even intestines to be seen, allowing scientists to observe its digestive system in action.
