Abstract
The predator-prey relationships between the California scorpionfish
Scorpaena guttata Girard and the octopus Octopus bimaculatus Verrill were examined
by observations of behavior in aquariums. California scorpionfish eat small
octopuses, but they specifically evade large octopuses attempting to stalk them, in
contrast with their defensive behavior, employing the venomous spines, against
other potential predators. They appear to discriminate between predatory behavior
and other kinds of behavior of octopuses. The observations suggest that, in nature,
octopuses prey on scorpionfish, principally on the juveniles.
