Abstract

Planktonic larvae of the annelid Pectinaria californiensis construct and inhabit cryptic houses through which they filter seawater to concentrate food. Although filtering houses may be unique to pectinariid larvae, other transparent and ephemeral structures are secreted by the larvae of many marine invertebrates and may be involved in the performance of a variety of critical larval functions.
