Xenoturbella japonica is a marine benthic worm-like species that belongs to the genus Xenoturbella. It has been discovered in western Pacific Ocean by a group of Japanese scientists from the University of Tsukuba. The species was described in 2017 in a study published in the journal BMC Evolutionary Biology,[1] and amended in 2018.[2]
Xenotrubella japonica is known for lacking respiratory, circulatory and an excretory system.[3][4][1]
