Abstract: The gills of cephalopods represent a potential site of regulation of
vascular peripheral resistance. Measurements of pressure-flow relationships in
the isolated gills of Octopus macropus and Nautilus pompilius gave no evidence of
autoregulation. Perfusion with putative neurotransmitters showed 5-hydroxytryptamine,
and possibly dopamine, to reduce vascular resistance. Physiological
concentrations of acetylcholine and noradrenaline did not alter resistance to
flow.
