A Dubois Account of Breeding Varanus Olivaceus in Captivity at the Paradise Reptile Zoo in Mindoro, Philippines

Abstract. Varanus olivaceus is one of the most valuable monitor lizards in wildlife trade and considered vulnerable throughout its range. A published report claiming “the world’s first successful breeding of V. olivaceus” is reviewed critically in the light of established facts about the reproduction of this species in captivity, and experience of the establishment in question in the year of the supposed breeding. Regulatory authorities and peer reviewers should require unambiguous proof of captive breeding success before accepting such claims in the future.
