  • Zoological institution study books provide life-history information from captive specimens (ref: Koor2009, Blijdorp, San_Diego)
  • Juvenile lives 3 till 4 yr in trees to avoid predation by adults (ref: Kerk2010)


  • Species data from pers comm. Don Boyer (curator of herpetology, Bronx Zoo)and Steve Conners curator of herpetology, Miami metro zoo)
  • Data obtained from Flores V. komodoensis population that are likely to have different life-history to island populations on Komodo or Rinca Island.
  • All data from captive specimens and corresponding parameters for wild specimens lacking with exception for some growth information contained within LavePurw2012
  • Males are assumed to differ from females by {p_Am} and E_Hp only
