 The common house gecko is ectothermic (“cold blooded”) and displays a variety of means of thermoregulating through behaviour.Its physiology has ramifications for its distribution and nature of interaction with native species, as well as reproductive success as an introduced species.Metabolically, the demand of the common house gecko is not significantly variable from other lizard species of a similar size, with Oxygen consumption appearing congruent with trends observed in other tropical, subtropical and temperate species of gecko.
