Veligers mature to a point called "competence" where they settle to the substratum and metamorphose to become the juvenile stage. During metamorphosis they lose their velum, and undergo external and internal changes that produce the juvenile.

Feeding or non-feeding veligers are possible, depending on which species has produced them. In a feeding veliger, the newly hatched larval stage is, in most cases, relatively "undeveloped" and must feed on phytoplankton
