About Furcifer verrucosus
Furcifer verrucosus, commonly known as the warty chameleon, is a large species of reptile endemic to the island of Madagascar. First described by Georges Cuvier in 1829, this chameleon is characterized by its distinctive physical features and specific habitat preferences. It is recognized for its spiny appearance, leading to common names such as the spiny chameleon or crocodile chameleon.
Description and Characteristics
The warty chameleon is a sizable species, with males reaching a total length of up to 56 centimeters (22 inches), while females are significantly smaller, growing to about 21 cm (8 inches). A notable feature is the casque, a helmet-like crest of scales on its head, and a small crest extending from its eyes to its snout. Both sexes possess low crests along their flanks, throat, and belly. Males are distinguished by a prominent crest of up to forty spines running along their back, a feature that is less pronounced in females, who instead have tubercles. Both sexes share a lateral line of large scales. Their long tail is prehensile, aiding in their arboreal movements. The general coloration is grey or brown, often marked with blotches or indistinct bands, and typically features an intermittent white streak on each side. Females tend to be paler, while males may exhibit green tinges on their belly, tail, and limbs.
Distribution and Habitat
Furcifer verrucosus is found exclusively on Madagascar, inhabiting much of the western part of the island and its drier southern regions. It is not typically found in primary rainforests but favors arid, disturbed environments, including areas close to the sea. As a terrestrial species, it spends time on the ground and also climbs among low bushes. During hot weather, it may seek refuge in sandy burrows to stay cool.
Biology and Conservation
The warty chameleon's diet consists primarily of insects, which it expertly catches using its long, sticky tongue. Reproduction involves the female laying one clutch of 30 to 60 eggs annually, with an incubation period of approximately 200 days. Juvenile chameleons take between six months to a year to reach maturity. Both Furcifer v. verrucosus and its close relative, Furcifer oustaleti, are listed under CITES (Convention on International Trade in Endangered Species), providing them protection against international trafficking.

Common wall gecko
The common wall gecko, scientifically known as Tarentola mauritanica, is a robust gecko species native to the western Mediterranean region of North Africa and Europe. Characterized by enlarged, tubercules that give it a spiny, armored appearance, this nocturnal insectivore is frequently observed on walls in urban and coastal areas. It has a long history of cohabitation with humans, particularly in Spain, where it acts as an insect hunter.
Moorish gecko
The Moorish gecko is a nocturnal lizard native to the western Mediterranean region of North Africa and Europe, often found on walls in urban and coastal areas. Its distinctive spiny appearance comes from enlarged, conic tubercles covering its back, legs, and tail. Primarily an insectivore, this robust gecko plays a role in controlling insect populations and has a long maturation period.
