El enigmático bivalvo Planktomya henscni ha sido considerado como un animal holoplamónico por casi un siglo. Alien and Scheltema (1972) demostraron que toda la evidencia indicaba hacia una concha bentónica con un estado larval inusitadamente largo. Esta concha bentónica ha sido encontrada finalmente en la parte tropical del Atlántico occidental, y aparentemente pertenece a la familia Sportellidae. Al compararla con las especies fósiles de esta familia muestra un tendencia hacia una prodisoconcha grande y un largo estado larval planctónico, aparentemente largo.The enigmatic bivalve Planktomya henseni has masqueraded as a holoplanktonic animal for nearly a century. Alien and Scheltema (1972) showed that all the evidence pointed to a benthic clam with an unusually long planktonic larval stage, This benthic clam has finatly been found in the tropical western Atlantic, and appears to be a member of the Family Sportellidae. Comparison with fossil species in this family shows a trend toward a large prodissoconch and apparently a long planktonic larval stage.
