Figure 4


Fig. 4. Appetitive and consummatory behaviors elicited by artificial sea water (ASW), and by the NO donor, in A. californica during the winter months, when most of them are immature. Data are shown separately for animals that responded to the NO donor by depositing an egg cordon (mature), and for animals in which no egg cordon was produced (immature). (A) The NO donor elicited a large increase in appetitive behaviors, with respect to that observed in response to ASW. In mature animals the appetitive behaviors stopped abruptly at the start of the consummatory behaviors, whereas in immature animals appetitive behaviors gradually declined over the hour of observation. (B) Consummatory behaviors were observed in mature animals.
