Behaviour and Ecology
It is a common misconception that chameleons of any kind can change colour to match any colour of their environments. All chameleons have a natural colour range with which they are born, and is dictated by their species. Colour change is, for the most part, subconscious. It is affected by temperature, mood, and light. If, for example, the colour purple is not within the range of colours to which their particular species can change, then they will never turn purple.
Like most species of chameleons, the panther chameleon is very territorial. It spends the majority of its life in isolation, apart from mating sessions. When two males come into contact, they will change color and inflate their bodies, attempting to assert their dominance. Often these battles end at this stage, with the loser retreating, turning drab and dark colors. Occasionally, the displays result in physical combat if neither contender backs down.

Famous quotes containing the words behaviour and, behaviour and/or ecology:
“... into the novel goes such taste as I have for rational behaviour and social portraiture. The short story, as I see it to be, allows for what is crazy about humanity: obstinacies, inordinate heroisms, “immortal longings.””
—Elizabeth Bowen (1899–1973)
“The methodological advice to interpret in a way that optimizes agreement should not be conceived as resting on a charitable assumption about human intelligence that might turn out to be false. If we cannot find a way to interpret the utterances and other behaviour of a creature as revealing a set of beliefs largely consistent and true by our standards, we have no reason to count that creature as rational, as having beliefs, or as saying anything.”
—Donald Davidson (b. 1917)
“... the fundamental principles of ecology govern our lives wherever we live, and ... we must wake up to this fact or be lost.”
—Karin Sheldon (b. c. 1945)
