A young female Sri Lankan tree viper.
For many years Patti and I kept and bred a couple of dozen species of tree vipers of several genera. Among my favorites was the Sri Lankan species, Trimeresurus trigonocephalus. They were of moderate size (usually 2 to 3 ½ feet) , usually of reasonably equable disposition, always of beautiful color, and since they are both dimorphic and dichromatic they are an easily sexed taxon. Males, the smaller gender usually have much more black in the lateral and dorsal pattern than the primarily green females. Additionally, this taxon does not require brumation or other pronounced temperature manipulations to be successfully bred. And when and if bred these long-lived arboreal pit vipers bear living young (neonates are7 ½ to 9 inches long) that usually feed readily on thawed pinkies. Litters of 20 to 25 have been reported but the females we kept usually birthed 5 to 10 babies once a year. This taxon is light-bodied enough to allow a keeper to incorporate sturdy vining plants (Epipremnums and/or Philodendrons) and horizontal tree branches into beautiful terrarium designs. How much easier and fulfilling could keeping a venomous snake be?
