Galápagos tortoises can live over 100 years, making them one of the longest-lived vertebrate animals.

Black mamba venom is highly toxic and can cause paralysis, shutdown of body systems, and is often fatal without antivenom.

Newts have the remarkable ability to regenerate lost limbs, organs, and even parts of their heart.

Reptiles lay amniotic eggs, which are encased in a protective shell and can be either leathery or calcified, depending on the species.

Some species of geckos utilize echolocation to navigate and hunt in the dark by making clicking sounds and listening for the echoes.

Poison dart frogs have skin toxins that are potent enough to deter predators; some native tribes use their poison for hunting.

Biodiversity hotspots for amphibians include the rainforests of Central and South America, Central Africa, and Southeast Asia due to the warm and moist climates.

Toads dig into the soil to hibernate during the winter, entering a state of brumation where their metabolism and body functions slow down.

Amphibians are cold-blooded, lay eggs in water, and undergo metamorphosis from a larval stage to an adult.

Geckos have specialized toepads that allow them to stick to and climb smooth vertical surfaces, due to microscopic hair-like structures.

Parthenogenesis is a form of asexual reproduction where females can produce offspring without male fertilization, seen in some reptile species.

The basilisk lizard can run across water for short distances using rapid movements and specially adapted toes to avoid sinking.

Reptiles generally have a lower metabolic rate compared to mammals and birds, which is why they can survive long periods without food.

Aestivation is a state of dormancy during hot, dry periods that allows amphibians to avoid desiccation.

Amphibians have permeable skin that allows for gas exchange but also makes them sensitive to environmental pollutants.

Albinism in reptiles is the absence of pigmentation, which results in a white or pinkish coloration and increased sensitivity to sunlight.

American alligators are found in freshwater wetlands such as marshes and swamps in the Southeastern United States.

The Eastern Box Turtle is recognized for its high-domed shell and ability to completely close its shell, using hinged plastrons for protection.

Chameleons change color to communicate and regulate their body temperature, not solely for camouflage as often believed.

Frogs have vocal sacs that act as resonating chambers to amplify their croaking during mating calls.

Salamanders can fully regenerate lost limbs, including the bones, muscles, nerves, and skin, a trait not common among vertebrates.

Reptilian scales serve multiple functions, such as protection from physical injury, prevention of water loss, and aiding in locomotion.

Green sea turtles are primarily herbivores, feeding on seagrasses and algae.

Some snakes have heat-sensing organs called pit organs, which allow them to detect warm-blooded prey in the dark.

The Komodo Dragon is native to the Indonesian islands and prefers hot, dry environments.

Olive Ridley turtles are known for their arribadas, where thousands of females come together on the same beach to nest simultaneously.

Tortoise shells are made of bone, covered by keratinous scutes, which protect them from predators and environmental elements.

Global amphibian populations are declining due to factors like habitat destruction, climate change, pollution, and a fungal disease called chytridiomycosis.

Caecilians are unique among amphibians for being limbless, resembling large worms or snakes, and are adapted for a burrowing lifestyle.

Anoles are known for their colorful throat fans or dewlaps, which are used for territorial displays and attracting mates.

Crocodiles possess specialized salt glands in their tongues, which can excrete excess salt from their bodies, allowing them to inhabit saltwater environments.

Amphiumas, or congo eels, breathe through both lungs and skin, enabling them to live in oxygen-poor aquatic environments.

Iguanas have a parietal eye, also known as a third eye, on top of their head, which is sensitive to changes in light and dark, helping to regulate their circadian rhythms.

Leopard geckos are nocturnal, becoming active at night to hunt for insects and avoid daytime predators and heat.

Horned lizards can squirt a stream of blood from their eyes to deter predators.

Red-eyed tree frogs have vibrant green bodies that blend into the foliage, with eyes that can startle predators when opened.

Axolotls exhibit neoteny, remaining in their larval aquatic form with gills throughout their adult life.

Monitor lizards are apex predators in their habitats with keen senses and physical strength. They eat anything from insects to larger vertebrates.
