While sampling marine plankton in a lab, a student finds a large number of fertilized eggs. The student raises some of the eggs in the laboratory for further study and finds that the blastopore becomes the mouth. The embryo develops into a trochophore larva and eventually has a true coelom. These eggs probably belong to (gastropod/nematode/Platyhelminthes/ or gastropod and nematode)?
