Cephalodella forficata Ehrenberg 1832
Cephalodella forficata, an "eye"less species; lateral view. A specific feature of this species is the red gastric glands of adult animals. (2)
 
Cephalodella forficata, lateral view; specimen from (3). In this image the dorsal antenna (DA) and retrocerebral organ, consisting of the retrocerebral sac (arrow) and the retrocerebral duct (marked by arrowheads) are visible.
 
Cephalodella forficata, lateral view; specimen from (7). Also in these two images the dorsal antenna (DA), the retrocerebral sac ((RCS), arrow) and the retrocerebral duct ((RCD), marked by arrowheads) are visible. Remarkable is the green color of the vesicles inside the RCS of this specimen, which arises questions like:
1.what is the origin of this green color?
2.has the green color something to do with the conspicuous orange color of the gastric glands?
2.what happens to the vesicles in the RCD?
