Xenoturbella churro

You don't want to take a bite out of this churro! Because in spite of its name, Xenoturbella churro, this is not a delicious fried dough snack at all. It's a deep-sea Gulf of California marine worm cunningly disguised as a churro!

Found in the Bathypelagic zone at 1,722 metres (5,600 feet), the worm is believed to feed on molluscs on the ocean floor. It has an orange-pink body with four deep furrows, and is rather sack-like. It has a mouth, but no anus. It doesn't have a brain, eyes, gills or kidneys, either. Because it's so simple and primitive, it's thought to belong near the base of the evolutionary tree of bilaterally symmetrical animals.
