Larval dispersal as a means of genetic exchange between geographically separated populations of shallow-water benthic marine gastropods
1. Ten species of prosobranch gastropod veligers collected from the open waters of the North Atlantic Ocean have been identified by comparison of their larval shells with the protoconchs of identifiable juvenile or adult museum specimens. The larvae described are those of Cymatium parthenopeum (von...
