Bothriechis schlegelii - The Eyelash viper is a venomous pit viper species found in Central and South America. Small and arboreal, these snakes are characterized by their wide array of color variations, as well as the superciliary scales over the eyes.
This two headed albino milk snake was born last year in Florida. The condition, called Polycephaly, occurs when monozygotic twins fail to separate completely. Most organisms with this condition will not live for long, but occasionally you will get cases like this one, where the snake(s?) seem healthy enough and can live for years. The heads act independently of one another, and will fight over food given the opportunity.
