Abstract: Literature suggests that in the lab the octopus will only exhibit stereotyped feeding behavior. This project analyzes the attack of Octopus rubescens when presented a crab under simulated natural conditions in the lab. Five octopus are kept in separate aquariums. After each octopus emerges at night, a crab was dropped into its aquarium. Using a 16 digit event recorder, the crab's movements and the octopus' actions were recorded. In this way I was able to determine quantitatively that the octopus' attack sequences vary irregardless of the crab's actions. It is unknown how well these results can apply in the field.
