The reef bass, Pseudogramma bermudensis, is an hermaphroditic percoid in which the testicular tissue is confined to a median lobe in the mid-dorsal wall of the oviduct. Development of an invagination of the ventral oviducal wall is correlated with the presence of maturing ova. These unique features indicate that Pseudogramma has had a separate evolutionary history and is not closely related to either the hermaphroditic Serranidae or the Grammistidae.
