This page contains the Notaspideans we have seen at Kwajalein. What used to be Notaspidea is now considered two different orders and that is how they are presented below. The pleurobranchs often vary considerably in color, and representative color forms are presented in the thumbnails below. Likewise, while we have not seen other color forms of Umbraculum at Kwajalein, in other areas the animal can come in red, black or white in addition to yellow.
