| Another phylum, the Pogonophora, are also vermiform animals with a trochophore larva. |
| The trochophore larvae depend on their internal yolk supply for energy. |
| All produce eggs, from which may emerge trochophore larvae, more complex veliger larvae, or miniature adults. |
| Most marine bivalves go through a trochophore stage before turning into a free-swimming veliger larva. |
| Many polychaetes hatch into a particular type of planktonic larva, the trochophore, which later metamorphoses into a juvenile annelid. |
| Although the features of the trochophore larva are relatively uniform among species within an order, the nature of the larva also depends upon other factors e.g., egg size and larval ecology. |
