Zazzanaxes spend most of their time in one spot, travelling mostly in order to find richer waters in a seasonal migration, or to search for mates. When two zazzanaxes of opposite sexes smell each other, they will crawl about the area until they come within range of their electrical sense. At this point, they turn the voltage up and seemingly try to fry each other. Weak zazzanaxes are injured in these encounters, but strong zazzanaxes are able to counter the changes in current move for move, channeling it through their own systems. If both partners are able to survive the courtship battle for several minutes, they will draw near enough to copulate. Fertilization is internal and the female will release her larval offspring into the sea some days later (she turns off her feeding cone during this time so as not to eat them accidentally), where they will live as plankton until settling onto the seafloor at the end of the season as adults. The diagram above is of a male and shows the penis (E).
Zazzanaxes are made mostly of repeating units called “fingers.” The defensive claws and electric spines are modified fingers. Fingers of varying sizes are used to rotate the centrifugal feeding cone, push food through the digestive system, push water through the water drain system, squeeze the reservoir for the water cannon, push semen out of the penis, and push blood through the vascular system. There is no central heart and the direction of blood flow is changed (see diagram four) to send highly oxygenated blood from the gills directly to whichever organ most needs it at the time. The blood fingers coordinate with each other by means of signaling molecules in the blood. Each finger contains a stiff rod, including the tiniest, which are single cells.
