Calumma tarzan
Calumma tarzan, commonly known as the Tarzan chameleon, is a species of lizard endemic to the Alaotra-Mangoro region of Madagascar. This chameleon is distinguished by its spade-like snout and a low casque, with males exhibiting darker coloration on their casque and neck compared to females. It inhabits forest fragments and has been designated a flagship species for conservation efforts in fragmented habitats.

About Calumma tarzan
Calumma tarzan: The Tarzan Chameleon
The Tarzan chameleon, scientifically known as Calumma tarzan, is a distinct lizard species endemic to the Alaotra-Mangoro region of Madagascar. This chameleon is recognized for its unique physical characteristics, including a spade-like snout formed by fused rostral crests and a notably low casque. Its coloration is typically green to light yellow, often displaying a dark band when the animal is under stress.
Physical Characteristics and Sexual Dimorphism
Adult Calumma tarzan typically measure between 119–150 mm (4.7–5.9 in) in total length, with a snout-to-vent length (SVL) ranging from 61–72 mm (2.4–2.8 in). A defining feature is the anteriorly fused rostral crests that create a spade-like projection extending slightly beyond the snout tip. Significant sexual dimorphism is observed in the casque and neck coloration: males present with brown to blackish hues, while females are adorned with green to light yellow tones. Furthermore, females exhibit a less pronounced rectangular rostral profile compared to males.
Habitat and Distribution
This species is found exclusively in central east Madagascar, primarily inhabiting forest fragments. Specifically, populations have been identified outside of Tarzanville in the Province of Moramanga. The fragmentation of forest habitats in Madagascar poses a significant challenge to its survival.
Conservation Significance
Calumma tarzan has been identified as a flagship species for conservation efforts in Madagascar's fragmented forests. Its colorful appearance and the scarcity of other prominent flagship species in its habitat make it a valuable representative for raising awareness and support for conservation initiatives. The ongoing fragmentation of forest habitats, exacerbated by governance issues, threatens not only Calumma tarzan but also other endemic wildlife, including lemurs and various bird species.
