Diet of the New Caledonian Gecko Rhacodactylus auriculatus (Squamata, Gekkonidae)

Aaron M. Bauer, R. A. Sadlier

Abstract


The diet of the large New Caledonian gekkonid lizard, Rhacodactylus auriculatus is highly varied and most prey items taken are relatively large. In addition to many types of arthropods, this lizard also includes geckos and especially skinks in its diet. It also appears to feed on pollen. Saurophagy in this species was previously predicted on the basis of dental morphology, whereas the inclusion of flower parts in the diet was signaled by observations reported in the 19th Century.

Keywords
