ABSTRACT IN 1936 Young1 described a structure in several genera of octopods (cephalopods) appearing on the ventral surface of both stellate ganglia (near the base of the stellar nerve most
distal to the mantle connective) which he termed the “epistellar body”. From histological considerations he hypothesized that this body might have a neurosecretory function. Nishioka _et
al._2 reinvestigated this structure in _Octopus_ in more detail and, by electron microscopy, made the significant observation that the epistellar body contains cells the surfaces of which
display microvilli suggesting rhabdomeric structures as seen typically in molluscan and arthropod visual photoreceptors. Later Nishioka _et al._3 extended their investigations to include
_Eledone moschata_ and presented not only further electron micrograph data on the rhabdomeric ultrastructure but also biochemical data indicating the presence of a rhodopsin photopigment.
Thus these investigators argued that the neurone-like cells of the epistellar body could be photo-receptors. We present here electrophysiological evidence clearly indicating the presence of
photoreceptor cells in the epistellar body. There is already electrophysiological evidence for extracellular photoreceptors in arthropods4–7, molluscs8,9 and for photoreceptors in the
