Paroctopus digueti is a good candidate for laboratory culture and biologicalexperimentation. During our efforts to achieve its conditioning tocaptivity the cannibalism has caused the most problems, even from birth,immediately attacking their siblings, so social interaction is reduced. As a shelter they prefer Anadara shells remaining hidden untildusk when looking for food. Return to their shelter to feed but keep it cleanby expelling hard debris, leftover food, and excreta. Octopuses becomehabituated to their keepers and with confidence and curiosity can take fooddirectly from tweezers.In addition to common octopus’ behaviors, we haveobserved curious things such as, three juveniles hunted newborn octopusestogether and brought them to their refuge to consume them. A female spawning atdifferent locations on the aquarium walls or a small one spawned inside therespirometer during a juvenile metabolism experiment. Some females haveeaten their eggs, and others are pulling opaque white eggs out of the shell,presumably dead or unfertilized. After the hatching, the female opens the shelter wideand spurt water, generating an outward flow to eliminate the remains of thechorion. If they are kept in individual containers within thesame pond, at least one goes out to explore, possibly in search of bettershelter, more food or simply as a routine. It is necessary to generate theethogram of P. digueti to initiate formal behavioral studies in thespecies.
