Cocculinoidea Explained

The Cocculinoidea is a superfamily of deepwater limpets (marine gastropods), the only superfamily in the order Cocculinida, one of the main orders of gastropods according to the taxonomy as set up by (Bouchet & Rocroi, 2005). The clade Cocciliniformia used to be designated as a superorder.

Taxonomy

According to Bouchet & Rocroi, 2005, the superfamily Cocculinoidea contains the families Bathysciadiidae and Cocculinidae.

The Cocculinoidea (Cocculinacea Dall, 1882) are combined with the Lepetelliodea (Lepetellacea Dall, 1882) in Cocculinoformia Haszprunar, 1987, referred to as a clade in Bouchet & Rocroi, 2005 although it used to be designated a superorder by Ponder & Lindberg, 1997. Bouchet & Rocroi (2005) leave the Cocculiniformia to consist only of the Cocculinoidea, having moved the Lepetelloidea to the Vetigastropoda.

(Note that before the stipulation by the ICZN, the majority of invertebrate superfamilies ended in -acea, or -aceae, not -oidea.)
