Description:
An intertidal population of Octopus digueti Perrier and Rochebrune was sampled without apparent sex or size bias (except for the smallest size classes) by placing artificial shelters in the intertidal zone. Comparisons of captures between the octopuses' natural shelters, large gastropod shells, and the artificial shelters, glass bottles, revealed no differences in the sex or size of the octopuses captured. The bottle trap technique is an inexpensive means of sampling 0. digueti. The technique provides large numbers of untraumatized octopuses and can define the local species distribution in this potentially shelter-limited population.
