| Abstract: | The results reported here demonstrate the existence of cannibalistic behaviour in laboratory-reared Tigriopus fulvus (Fischer, 1860) females towards first-stage non-related nauplii; mothers, sparing their own offspring, do not share this behaviour. The phenomenon is related to the probability of nauplius/female encounters. It is suggested that mother/offspring recognition is mediated by a chemical compound. |
