A strange microscopic creature which has “a mouth but no anus” and from which humans were earlier thought to have descended has now been found to be a part of a different family tree.
The bag-like sea creature known as a Saccorhytus also likely moved by wriggling, previous studies had revealed.
Its large mouth was found to be surrounded by spines and holes which were interpreted as pores for gills.
