Oh my goodness! Unless you are a Tree of Life developer,
you really shouldn't be here. This page is part of our beta test site, where we
develop new features for the ToL, often messing up a thing or two in the

Ventral view of an immature, female V. infernalis with the mantle cavity of cut open. Posteriorly the lining of the mantle cavity has been cut away to better view the visceral nucleus. Note that there is no abdominal septum, no ink sac, no anal flaps. The visceropericardial coelom (dark region surrounding the ventricle, stomach and caecum) is large. Posteriorly, in the ventral midline, the mantle muscle terminates on the conus of the gladius. The photograph on the right shows a mature female. The arrangement of the viscera looks very different. The gladius, with a small rostrum and a dark "apical organ", is visible because surrounding tissue has been removed.

Figure. View of a portion of the mantle cavity of V. infernalis. The stellate ganglion (arrow), a characteristic structure of cephalopods, appears as only a slight enlargement of a large mantle nerve. The nerve running toward the oviducal gland is the fin nerve. Photograph by R. Young.
