Behaviour and territorialism in Trichosurus vulpecula (Marsupialia)

This paper reports observations made on captive opossums in the Orongorongo Valley.

Direct visual or acoustic signals between adults are mainly aposematic and indicate risk of conflict rather than threat. Lack of conventionalised dominance and submission prevents group formation, since the response to aggression is fight or escape. Dispersion does not depend on aggression; most usually it
