Appearance
O'Shaughnessy's chameleon, being closely related to Parson's chameleon, is similar in shape and color but slightly smaller. Albert Günther, the first to scientifically describe the species, stated that the type specimen is a male measuring 15.5 inches (39.4 cm) in total length, including its tail which is 9 inches (22.9 cm) long. It is mostly brownish gray, with a darker throat and jaw. Although lacking horns, the male of the species has a short, bony structure on the snout. The female does not have this structure.
Distribution
O'Shaughnessy's chameleon has a geographic range of about 18,000 square kilometers (6,950 square miles) throughout the southeastern portion of the central highlands of Madagascar. Its distribution extends from Tsinjoarivo, Ambatolampy in the north to Andohahela National Park in the south. The species is highly dependent on intact, humid forest as its habitat, living in lower densities on selectively logged territories.References:
