A rare two-headed crested gecko, born this summer at a breeding business in northeastern Pennsylvania, is defying the odds of survival. The gecko, nicknamed Simon and Garfunkel, hatched on June 29th at Rockstar Geckos.
Polycephaly, the condition of having multiple heads, can result from genetic or environmental factors during embryonic development. While reptiles like snakes and turtles are more commonly observed with this condition, it can occur in various species. According to Rockstar Geckos, past instances of two-headed geckos have rarely survived long.
Despite the challenges associated with polycephaly, Simon and Garfunkel have shown remarkable progress. Initially, their movements appeared uncoordinated as each head seemed to exert independent control. However, recent updates indicate that the two heads are coordinating their movements, with neither appearing dominant. They are also eating independently and without assistance.
"They move around pretty well even though it appears they each want to go in separate directions sometimes," Rockstar Geckos noted in an early July update, two weeks after the gecko's birth. By four weeks old, the geckos weighed approximately 1.8 grams. Their heads are positioned in a way that prevents them from harming each other.
Crested geckos are native to New Caledonia and are tree-dwelling lizards that typically reach 8 to 10 inches and weigh between 35 to 45 grams when fully grown. Fans have expressed support and encouragement for the geckos' continued health and longevity.
Rockstar Geckos has committed to providing further updates as Simon and Garfunkel reach new developmental milestones. This particular instance of polycephaly has garnered significant attention, highlighting the resilience of the animal despite its rare condition.
