Provisional Structures of the Larva of Nipponomicrura sp. (Nemertea, Pilidiophora)

Timur Yu. Magarlamov, Alexei V. Chеrnyshev

Nemertea is a phylum of predominantly marine worms that exhibit various larval forms, including the iconic pilidium. Pelagic lecithotrophic pilidia are considered more derived than pelagic planktotrophic pilidia, but data on the structure of lecithotrophic larvae are limited to the light-optical level. …
