Which oranganism from class scaphopoda shows following larval stage?

In the class Scaphopoda, the organism known as dentalium, commonly referred to as "tusk shells," exhibits a larval stage called the trochophore larva. This larval stage is characterized by a free-swimming, ciliated form that is typical in many mollusks, allowing for dispersal and development before settling into the adult form. After the trochophore stage, it typically undergoes metamorphosis into the veliger stage before transitioning into the adult tusk shell.
