groups have long been considered close relatives because they share trochophore larvae. In the classical era, Aristotle divided animals, based on his...

hatches to release a free-swimming trochophore larva, typical of many other mollusc groups. In a few cases, the trochophore remains within the egg (and is...
long been considered close relatives because of the common presence of trochophore larvae, but the annelids were considered closer to the arthropods because...
a short stage lasts a few hours or days before the eggs hatch into trochophore larvae. These later develop into veliger larvae which settle on the seabed...

fertilize their eggs externally. The fertilized eggs typically hatch into trochophore larvae, which float among the plankton, and eventually metamorphose into...
planktonic, free-swimming, trochophore larvae, also known as the early umbo stage, which have cilia and a small shell. The trochophore larvae depend on their...

specifically to the Lophotrochozoa. This implies that the ectoproct larva is a trochophore with the corona being a homologue of the prototroch; this is supported...
eggs of polychaetes are deposited in the sea where they develop into trochophore larvae that disperse as part of the plankton, while the yolky eggs of...
Nereids form a larval stage which is similar to that of molluscs – i.e. a trochophore larva. The genus Nereis contains the following species: Nereis abbreviata...
