Abstract:


Food imprinting has both ecological and evolutionary significance but the generality of these


patterns for octopods remains unknown. We aim to determine the prey preference of Octopus


berrima hatchlings and whether it may be modified through imprinting. Firstly, hatchlings were


given isopods, amphipods and mussels to determine their prey preference ranking. In a separate


experiment, embryos were exposed to the visual and chemical stimuli of either isopods, amphipods


or mussels separately at least a week before hatching. A prey preference test on hatchlings using all


three prey types was conducted. We found that O. berrima had a preference ranking of isopods >


amphipods > mussels. However, they retained their isopod prey preference regardless of the prey


type they were embryonically exposed to, indicating that it is likely pre-determined as a result of


innate biological processes rather than from life experience, providing evidence that imprinting


does not occur in O. berrima.
