They are powerful constrictors and feed on a variety of large prey, including capybaras, deer, and even jaguars, which they constrict and swallow whole.
10. Green Sea Turtle (Chelonia mydas)
The green sea turtle is a large marine turtle species known for its long oceanic migrations. These turtles have a smooth, heart-shaped carapace and are named for the greenish colour of their fat, which is caused by their herbivorous diet of seagrasses and algae.
Green sea turtles play a crucial role in maintaining the health of seagrass beds, which provide habitat and food for a variety of marine species. However, they face numerous threats, including habitat loss, pollution, and poaching for their eggs and meat.
11. Inland Taipan (Oxyuranus microlepidotus)
The inland taipan is considered the world’s most venomous snake, native to the semi-arid regions of eastern central Australia. These slender snakes can grow up to 2.5 meters in length and have highly potent venom that is primarily adapted for hunting small mammals.
Inland taipans are typically found in cracked clay soils and abandoned animal burrows, where they lead a shy and reclusive lifestyle. Despite their highly potent venom, inland taipans are not considered a significant threat to humans due to their remote habitat and infrequent encounters.
12. Komodo Dragon (Varanus komodoensis)
The Komodo dragon is the world’s largest living lizard species, endemic to several Indonesian islands. These impressive reptiles can grow up to 3 meters in length and weigh over 70 kg. Komodo dragons have bacteria-laden saliva that can cause septicemia in their prey, making them highly effective predators.
As apex predators, they feed on a variety of large prey, including Timor deer and water buffalo. However, due to habitat loss, human encroachment, and illegal hunting, Komodo dragons are considered a vulnerable species.
13. Leatherback Sea Turtle (Dermochelys coriacea)
The leatherback sea turtle is the largest living turtle species, known for its long oceanic migrations across tropical and temperate waters worldwide. These unique turtles have a leathery carapace that lacks the typical bony plates found in other sea turtles, and they are capable of maintaining a higher body temperature than the surrounding water.
Leatherback sea turtles feed primarily on jellyfish and are threatened by entanglement in fishing gear, plastic pollution, and climate change.
14. Mojave Desert Tortoise (Gopherus agassizii)
The Mojave desert tortoise is a medium-sized tortoise species native to the Mojave and Sonoran deserts of the southwestern United States. These tortoises have a high-domed carapace and are adapted to survive in arid environments by storing water in their bladder.
Mojave desert tortoises are herbivorous and have a slow metabolism, allowing them to live up to 80 years in the wild. However, they face threats such as habitat loss, off-road vehicles, and the spread of respiratory diseases.
15. Nile Crocodile (Crocodylus niloticus)
The Nile crocodile is a large crocodilian species native to Africa and Madagascar. Adult males can reach lengths of up to 6 meters and have powerful jaws and armoiur-like scales.
Nile crocodiles are found in a variety of aquatic habitats, including rivers, lakes, and wetlands, where they feed on an opportunistic diet of fish, reptiles, birds, and mammals. These powerful predators are also known to be a significant threat to humans, and human-crocodile conflicts are a concern in many parts of their range. Conservation efforts aim to protect the species while minimising these conflicts.
16. Puff Adder (Bitis arietans)
The puff adder is a venomous snake species widely distributed across Africa and parts of the Middle East. These stout-bodied snakes can grow up to 1.5 meters in length and have distinctive chevron-shaped bands along their body. Puff adders have highly potent venom with hemotoxic effects, causing severe pain, swelling, and tissue damage in their victims.
Due to their widespread distribution and their tendency to rely on camouflage rather than fleeing when approached, puff adders are responsible for the most snakebite fatalities in Africa.
17. Saltwater Crocodile (Crocodylus porosus)
The saltwater crocodile is the largest living reptile species, native to the coastal regions of the Indian and Pacific Oceans. Male saltwater crocodiles can grow up to 6 meters in length and weigh over 1,000 kg, making them formidable predators with powerful jaws and armoiur-like scales.

As apex predators, saltwater crocodiles play a crucial role in their ecosystems, but their presence can also lead to human-crocodile conflicts. Conservation efforts focus on protecting the species while managing these conflicts.
18. Slow Worm (Anguis fragilis)
The slow worm is a legless lizard species native to Europe, West Asia, and North Africa. Despite their snake-like appearance, slow worms can be distinguished from snakes by their blinking eyelids and the presence of ear openings.
These lizards have smooth, glossy scales and are capable of autotomizing (shedding) their tail when threatened. Slow worms are typically found in grasslands, woodland edges, and gardens, where they feed on slugs and earthworms.
19. Spectacled Caiman (Caiman crocodilus)
The spectacled caiman is a small to medium-sized crocodilian species native to Central and South America. These caimans are named for the bony ridge between their eyes that resembles a pair of spectacles.
They also have four to five transverse bands on their body, which helps to distinguish them from other caiman species. Spectacled caimans are found in a variety of aquatic habitats, including freshwater rivers, lakes, and wetlands, where they feed on fish, crustaceans, and small mammals.
These adaptable reptiles can also thrive in human-modified landscapes, such as agricultural areas and irrigation canals.
20. Thorny Devil (Moloch horridus)
The thorny devil is a small, spiky lizard species native to the arid regions of central Australia. These unique lizards are covered in sharp, conical spikes that serve as a defense against predators.
Thorny devils are also capable of changing colour to match their surroundings, providing them with excellent camouflage. Their specialised diet consists almost entirely of ants, which they capture using their sticky tongue.
Thorny devils have a unique water-collecting system that allows them to channel dew and moisture from any part of their body to their mouth, enabling them to survive in dry environments. When threatened, these slow-moving lizards often remain motionless, relying on their camouflage for protection.
21. Tuatara (Sphenodon punctatus)
The tuatara is a unique reptile species endemic to New Zealand, often referred to as a “living fossil” due to its ancient lineage. These reptiles have a spiny crest along their back and a “third eye” (parietal eye) on top of their head, which is sensitive to light.
Tuataras are also known for their ability to hear low-frequency sounds, which is unusual among reptiles. These long-lived reptiles can survive for up to 100 years and have a slow metabolism. Tuataras are typically found in coastal forests and on offshore islands, where they feed on insects, spiders, and small lizards.
Due to threats such as habitat loss and introduced predators, tuataras are the focus of intensive conservation efforts in New Zealand.
