Four-Eyed Creatures Discovered Are Brand New Species

As for their appearance, besides the bright-red color, the four-eyed worms have eight enlarged cirri, which are hair-like or feather-like appendages; dorsal cirrophores with a dorsal foliose lobe, which is a leaf-like structure where the cirri are attached; biramous parapodia, which are the paired, lateral extension on each body segment; and no media antenna, which is odd, considering that many related species have a central antenna. Furthermore, Parahesione apiculata has unique finger-like projections on the leaf-like structure on its back, which Parahesione pulvinata, does not have.
