Abstract
Here we report for the first time that adult Hapalochlaena lunulata
(Quoy & Gairnard, 1832), which has a vestigial ink sac, is capable of inking. Ink
was released under three different agonistic conditions: female-female aggression,
rejection of mating attempt, and when attacked by a predator. We observed
no apparent reaction to the ink by the other animals involved in these
interactions.
