“Right now, in the northeast district of Nebraska, we have three technicians who are responsible for doing boat inspections, handing out literature and collecting veliger samplings.”

Crassostrea gigas is also an interesting model for developmental biology owing to its mosaic development with typical molluscan stages, including trochophore and veliger larvae and metamorphosis.

There is a veliger stage in development, but the velum is reduced.
