The Green Crested Lizard is a striking arboreal reptile native to Southeast Asia. It can be found in Borneo, Indonesia, Malaysia, Singapore, southern Thailand and Myanmar, the Philippines, and the Sunda Islands. In the Philippines, its presence has been recorded in several islands including Bohol, Cebu, Luzon, Mindanao, Negros, Panay, Samar, Sulu, and a few records from Mindoro.
This slender lizard is easily recognized by its vivid green coloration, often with a bluish tint on the head, and a distinct triangular crest along the nape. A dark ring around each eye and a black eardrum (tympanum) add to its unique appearance. True to its genus, it has an exceptionally long tail, making up about 75% of its total length. Highly elusive and agile, the Green Crested Lizard can even change its color to dark brown to blend into its surroundings for effective camouflage.
Preferring life among the trees, this species thrives in primary and secondary forests, but it can also adapt to disturbed habitats such as parks, gardens, and urban green spaces. A study in the Mount Makiling Forest Reserve documented this lizard in the sub-canopy and canopy layers, often observed clinging to the trunks of slender trees—especially while asleep.
A skilled insect and skink hunter, the Green Crested Lizard helps maintain ecological balance by controlling insect populations. Like most lizards, it is oviparous, laying eggs that hatch into miniature versions of the adults.
However, the species faces threats from deforestation and the illegal wildlife trade, which endanger its natural habitats and survival.
So, on your next visit to the Makiling Botanic Gardens, keep your eyes peeled—you might just spot one of these beautiful emerald climbers resting quietly among the trees! (by MMCaña, AALimpiada, JBBalatibat 2025)
