Surface is smooth, consisting of a thin, delicate, translucent membrane. The ectosomal membrane is damaged in many areas of the body, showing a highly cavernous subectosomal tissue. Ectosome damage makes difficult to discriminate the occurrence of oscules from ectosome breakages. The consistency is hard but friable. The color in alcohol is beige.
