Earlier this summer a rare occurrence was discovered at CREW. A dusky pygmy rattlesnake gave birth to six offspring, three of which were amelanistic – meaning they lack the dark pigment (melanin) in their skin. According to Kevin Enge , a herp expert with the Florida Fish and Wildlife Commission, this is extremely rare and to have three of the six born amelanistic is quite amazing. No amelanistic pygmies have ever been documented before in Florida.
It is likely these three would not survive long in the wild because their rare coloration makes them easy to see and more vulnerable as prey. Below is a picture of the adult (with typical coloration) and one of the three amelanistic juveniles. Pretty cool, huh?
The location and the time of discovery were kept secret until after the young dispersed in order to prevent collectors from trying to find and collect them to sell. We assume that nature has taken its course, because after about five days the snakes had all moved on and haven’t been seen since early July.
