Reptiles: Snakes, Lizards and Crocodilians

Explanation: The inland taipan (Oxyuranus microlepidotus) from Australia has the most toxic venom of all land snakes. A single bite contains enough venom to kill about 100 adult humans.

Explanation: The Komodo dragon (Varanus komodoensis) can reach 3 meters in length and weigh over 70 kg. It lives exclusively on a few Indonesian islands and is a formidable predator.

Explanation: Geckos have millions of setae (microscopic hairs) on their feet that create Van der Waals forces, allowing them to stick to almost any surface, even smooth glass.

Explanation: The gharial (Gavialis gangeticus) from South Asia has an extremely thin and elongated snout, perfectly adapted for catching fish. It is one of the most endangered crocodilians in the world.

Explanation: The flying snake (genus Chrysopelea) from Southeast Asia can flatten its body and undulate through the air to glide distances of up to 100 meters. It doesn't truly fly but glides with remarkable precision.

Explanation: Of the approximately 3,500 known snake species, only about 600 are venomous, and among those, about 200 pose a real danger to humans. The vast majority of snakes are harmless.

Explanation: The blue-tongued skink from Australia uses its bright blue tongue as a defense mechanism. When threatened, it opens its mouth wide and displays its colorful tongue to scare off predators.

Explanation: Antarctica is the only continent without snakes due to its extremely low temperatures. As cold-blooded animals, reptiles cannot survive in such a frigid environment.

Explanation: Caudal autotomy allows many lizards to detach their tail when caught by a predator. The tail continues to move, distracting the predator while the lizard escapes. It then regrows.

Explanation: The reticulated python (Python reticulatus) from Southeast Asia holds the record for the longest snake, reaching over 8 meters. The green anaconda is heavier but generally shorter.

Explanation: Crocodiles have a narrower, V-shaped snout, while alligators have a wide, U-shaped snout. Additionally, crocodiles' lower teeth are visible when their mouths are closed.

Explanation: The basilisk, nicknamed the "Jesus Christ lizard," can run on water thanks to its webbed hind feet and speed. It creates air pockets under its feet that keep it on the surface for a few seconds.

Explanation: Snakes use their forked tongue to "taste" the air and detect scent particles. These particles are then analyzed by Jacobson's organ in their palate, giving them a chemical image of their environment.

Explanation: The Mexican beaded lizard (Heloderma horridum) from Mexico is the cousin of the Gila monster and shares the title of only truly venomous lizards. Their venom is produced by glands in the lower jaw.

Explanation: The leatherback sea turtle (Dermochelys coriacea) is the largest sea turtle, reaching up to 2 meters in length and weighing up to 900 kg. Unlike other sea turtles, its shell is covered with leather rather than scales.

Explanation: The spitting cobra can project its venom with precision up to 2-3 meters, targeting the eyes of its adversaries. This venom causes intense pain and can cause temporary or permanent blindness if not rinsed quickly.

Explanation: Molting (or ecdysis) allows snakes to renew their worn skin and get rid of parasites. A healthy snake molts several times a year, and the skin is usually shed in one piece.

Explanation: Rosette's chameleon can project its tongue to a distance equivalent to 2.5 times its body length in just 0.07 seconds. It is one of the fastest movements in the animal kingdom.

Explanation: Pit organs (or loreal pits) are organs located between the eyes and nostrils of certain snakes like pythons and rattlesnakes. They detect infrared radiation emitted by warm-blooded prey.

Explanation: The tuatara from New Zealand is the only survivor of the order Rhynchocephalia, a group that existed 200 million years ago. Although it resembles a lizard, it belongs to a distinct and older order.
