The Morelet's crocodile is a large aquatic reptile in the family Crocodylidae, measuring 2–3 m in length, with a robust body, greenish-brown scaly skin and a broad head. It inhabits coastal lakes, rivers, swamps and freshwater lagoons, occasionally brackish waters, feeding mainly on fish, birds and small mammals. During nesting, the female builds a mound of vegetation debris on the shore and lays 20–45 eggs, which she guards for about 80 days.

The Marsh Crocodile, also known by the scientific name Crocodylus palustris, is a medium-sized reptile that can reach about 4 to 5 meters in length. Its body is typically olive to brown, with darker patterns that allow it to effectively blend into the swamps, rivers, and lakes of its habitat. This crocodile is primarily carnivorous and feeds on fish, birds, and small mammals, but it can also hunt larger animals when they venture too close to the water. The Marsh Crocodile is known for its patience and discretion when hunting, often remaining still for hours before seizing its prey. In terms of distribution, it is found in the Indian subcontinent, particularly in India, Pakistan, Bangladesh, and Sri Lanka. Although primarily sedentary, it can move short distances in search of new habitats. This species is listed as vulnerable due to habitat loss and hunting for its skin. Major threats include the draining of swamps, water pollution, and conflicts with human communities.

The Phelsuma madagascariensis, or Madagascar day gecko, is a colorful and fascinating lizard native to Madagascar. It is renowned for its bright colors, often green with red and blue spots, which help it blend into its natural environment. Typically measuring between 20 and 25 cm, this gecko is diurnal, meaning it is active during the day. It primarily inhabits humid tropical forests but can also be found in gardens and plantations. Although mainly insectivorous, it also feeds on nectar and fruits. Its ability to climb smooth surfaces thanks to its adhesive pads makes it an excellent climber.

The Marine Iguana is a unique species found exclusively on the Galápagos Islands. This iguana is the only reptile to have adapted to aquatic life, feeding on marine algae that it collects underwater while diving. It has a distinct morphology with a robust body and a long tail, allowing it to swim efficiently. Marine iguanas are often seen basking on rocks in the sun to regulate their body temperature after their dives into cold water. This thermal hibernation behavior is essential for their survival in the Galápagos environment.

The Lampropeltis triangulum, commonly known as the milk snake, is a non-venomous snake from the Colubridae family. It is famous for its colorful patterns that mimic those of venomous coral snakes, a classic example of Batesian mimicry. This snake is generally medium-sized, measuring between 60 and 120 cm in length. Its coloration varies depending on the subspecies, but it often features red, black, and white or yellow bands. It inhabits a variety of environments, from forests to grasslands, and primarily feeds on small mammals, birds, and other reptiles. Nocturnal by nature, it is mostly active at night and rests during the day.
