About the Churro
Discovered deep in the Gulf of California, 1,722 meters (about 5,600 feet) below the surface, Xenoturbella churro is a 10 cm-long (4-inch) marine worm, one of half a dozen species now known in the genus. It is representative of a group of primitive worm-like animals that are the earliest branch in the family tree of bilaterally symmetrical animals, including insects and humans.
Like some of its relatives, X. churro is believed to feed upon mollusks, such as clams. The new species is uniformly orange-pink in color with four deep longitudinal furrows that reminded the authors of a churro, a fried-dough pastry popular in Spain and Latin America. These primitive creatures have a mouth, but no anus, and are a reminder of the amazing biodiversity found in the world’s oceans.
