Its tongue, extremely long and fast, allows it to capture insects with remarkable precision. Though discreet, it plays a crucial role in the ecosystem by regulating insect populations.
The Calumma brevicorne, or short-horned chameleon, is a fascinating species of chameleon endemic to Madagascar. This reptile is distinguished by its short nasal horns and its ability to change color to blend into its environment. It primarily inhabits the island's humid forests, where it feeds on insects. This chameleon is diurnal and spends most of its time hunting and moving slowly among the branches. Its adult size generally ranges between 15 and 20 cm. Although it is relatively tolerant of human presence, it is essential to respect its natural habitat to ensure its survival. The Calumma brevicorne is currently classified as near-threatened due to deforestation and habitat loss.
The Spiny Chuckwalla, scientifically known as Sauromalus hispidus, is a large lizard endemic to San Esteban Island in the Gulf of California, Mexico. This reptile is recognized for its rough, spiny skin, which helps it blend into its rocky environment. It primarily feeds on vegetation, including flowers and leaves. Males are generally larger than females and display more vibrant colors. This lizard is well adapted to its arid habitat and can withstand long periods without water.

It is highly agile and spends most of its time hunting fish, amphibians, and small reptiles, which it captures by diving or swimming. Though mainly terrestrial, it is also an excellent swimmer. The species is protected in some areas due to habitat loss. The European Water Snake plays an important role in regulating amphibian populations and controlling small aquatic animals.
The Saltwater crocodile is the largest of the crocodiles, reaching up to 7 meters in length. It lives in the saline and brackish waters of the coasts of Southeast Asia, northern Australia, and the islands of the Indian Ocean. A powerful predator, it primarily feeds on fish, birds, and mammals, including large prey such as buffaloes and even sharks. While it is often feared for its size and power, it remains discreet in shallow waters and mangrove swamps. Due to hunting and habitat loss, the Saltwater crocodile is classified as a vulnerable species.
The Smith's green-eyed gecko (Gekko smithii) is a medium-sized nocturnal lizard (total length up to 35 cm, SVL 19 cm) with olive-green to brown mottled dorsal coloration and a pale throat bordered by dark mottling. Endemic to tropical and secondary forests of Southeast Asia (Thailand, Malaysia, Indonesia, Myanmar, Singapore), it occupies tree trunks and riparian vegetation where it forages for insects and arachnids. Reproduction occurs year-round, with females laying clutches of two eggs followed by an incubation period of 60–90 days. It uses crevices for shelter, produces harsh calls to communicate, and exhibits moderate wariness.
The Sikora's Leaf-tailed Gecko, Uroplatus sikorae, is a master of disguise, blending seamlessly into its surroundings with skin that mimics tree bark.

Its leaf-shaped tail is not only a tool for camouflage but also a means of communication with its peers. Measuring between 15 and 20 cm, it primarily feeds on insects. Although its appearance is striking, it is harmless to humans.
The Satanic Leaf-Tailed Gecko, Uroplatus phantasticus, is a master of camouflage native to Madagascar. Its ability to blend into its surroundings is remarkable, thanks to its skin that mimics the appearance of dead leaves. This small reptile, measuring about 10 cm, has a leaf-shaped tail that allows it to effectively hide from predators. Primarily active at night, it feeds on insects and other small invertebrates. Its coloration ranges from brown to gray, with occasional reddish hues, enabling it to blend into leaf litter. Although fascinating, it is vulnerable to deforestation and habitat loss.
The sand lizard, Lacerta agilis, is a medium-sized reptile, typically measuring between 15 and 25 cm in length, including the tail. Its coloration ranges from brown to green, with spotted patterns that help it blend into its surroundings. Males often display a brighter green hue, especially during the breeding season. This lizard is primarily found in Europe, favoring open habitats such as grasslands, sand dunes, and forest edges. Active during the day, it basks in the sun to regulate its body temperature. It feeds on insects, spiders, and occasionally small invertebrates. Although its conservation status is concerning in some areas, it remains relatively common in others.
The Schreiber's Green Lizard, or Lacerta schreiberi, is a fascinating reptile primarily found in the Iberian Peninsula. This lizard is particularly recognizable by its bright green color, often speckled with black spots, which allows it to blend into its natural environment. Males display a vibrant blue throat, especially during the breeding season. They prefer humid and wooded habitats, such as oak forests and wet meadows, where they can hide among dense vegetation.
