Abstract: 
In the organs of the digestive tract of Nautilus pompilius catecholamines and serotonin have been shown in the nerve endings by fluorescence histochemical methods. HPLC analysis confirm that noradrenaline and dopamine occur in all organs, while in the midgut gland only adrenaline is found. Using immune-histochemical methods against the tetrapeptide FMRF-amide and serotonin, positive reactions have been demonstrated within terminal nerves of the tunica muscularis of the oesophagus, crop, stomach, caecum, midgut and rectum. Additionally, histo- and cytochemical proof of acetylcholinesterase was found in the tunica muscularis of the oesophagus, crop, stomach, caecum, midgut, and rectum. The findings give evidence that similar to the coleoids an antagonistic cholinergic-aminergic neuroregulation, which seems to be modulated by FMRF-amide, also exists in the digestive tract of N. pompilius.
