Boa constrictor longicauda

From Northwestern Peru, the Tumbes region, this is one of many unique and isolated subspecies of Boa constrictor.  Relatively new to captive breeding programs there are currently two morphs, Anerythristic and Hypomelanistic.  So far only Anerythristics have proven genetic.  Probably the most unique thing about this subspecies is the extreme polymorphic variance within a single litter.  Another interesting trait would be the significant ontogenetic color change that these boas undergo as they mature.

Taxonomic information: Price and Russo 1991; scale count 60-76 dorsal rows; 243 to 247 ventrals; 50-67 subcaudals; average 19-21 saddles.
