I received this photograph of a juvenile female Wagler's Pit-viper (Tropidolaemus wagleri) from Dionne Teo just after I finished "slogging" on this species. She encountered this snake on 30 October 2006 in Lower Peirce Reservoir at about 4 pm. The patterns on this individual is unlike those on other specimens posted in my previous entry. This is a rarely (relatively) seen juvenile female with bars instead of dots seen in juvenile males. This is what scientists call "sexual dimorphism". Will be interesting to find out the evolutionary cause for this phenomenon.
