Platynereis is a genus of marine annelid worms.[1][2]

The species Platynereis dumerilii is used in development biology to study development (embryogenesis), in particular because their embryos are largely transparent, and thus easy to follow.[3] Apical organs such as this one are photosensitive which is a key component in their formation. They also have a common ancestor with cnidarians and bilaterians.[4]
