The vertical distribution of late stage, or pediveliger, larvae of several bivalve mollusks was examined in a west Florida estuary. The study site was an artificial canal, and the water was shallow (1.5 in) and well mixed, with only modest currents. Pediveligers of three bivalve taxa were collected: the eastern oyster Crassostrea virginica; the crested oyster Ostrea equestris; and unidentified shipworms (Teredinidae). Despite the shallow and well-mixed water column, larvae exhibited vertical zonation, with most larvae of all three species collected from lower in the water column. The larvae of C. virginica and shipworms showed no significant effect of time …
