This Bizarre Sea Worm Branches Like a Tree, And Each Segment Has Its Own Butt 3 MAY 2021 Nature is so weird. You can have worms living in the deep sea that are completely butt-free… while in reef-dwelling segmented worms whose bodies branch like a tree from its head, each branch ends in a separate butt.
This species is called Ramisyllis multicaudata, and it's possibly the strangest worm on the planet. It was first discovered in 2006, and formally described in 2012. Now, for the first time, scientists have conducted a detailed study of its anatomy, finally revealing more about this enigmatic creature - and raising even more questions about how it lives its bizarre life.
