Where Do Lizards Live?
Lizards live almost everywhere! They're found on every continent except Antarctica. Lizards have adapted to live in deserts, rainforests, mountains, grasslands, and even cities!
Most lizards love warm climates! As cold-blooded animals, lizards depend on their environment to regulate body temperature. You'll find the most lizard species in tropical and subtropical regions.
Desert lizards handle extreme heat! Fringe-toed lizards run across hot sand using fringed toes like snowshoes. They dive into sand to escape heat. Thorny Devils in Australia have special skin channels that collect dew and direct water to their mouths!
Rainforest lizards live in trees! Many rainforest lizards, like anoles and tree monitors, spend their entire lives in the canopy. They have special adaptations like prehensile tails for gripping branches.
Some lizards are excellent climbers! Geckos have special toe pads covered in millions of tiny hairs. These hairs use molecular forces to stick to surfaces - geckos can even walk upside down on ceilings!
A few lizards live in or near water! Marine iguanas of the Galapagos Islands swim in the ocean to eat seaweed. Water dragons and basilisks live near rivers. Basilisks can even run across water on their hind legs!
Many lizards are solitary! Unlike social animals, most lizards live alone. They only seek out other lizards during mating season. Some species, like fence lizards, defend territories from other lizards.
What Do Lizards Eat?
Different lizards eat different things! Lizard diets are incredibly varied.
Carnivorous lizards eat:
- Insects (crickets, beetles, flies)
- Spiders and scorpions
- Worms and snails
- Other lizards
- Small mammals and birds (large species)
Herbivorous lizards eat:
- Leaves and flowers
- Fruits and berries
- Cacti and succulents
- Algae and seaweed (marine iguanas)
Omnivorous lizards eat both:
- Insects and plants
- Fruits and small prey
- Whatever is available!
Most small lizards eat insects! Lizards are excellent pest controllers. A single lizard can eat hundreds of mosquitoes, flies, and other bugs. This makes them helpful to have around!
Chameleons have incredible tongues! A chameleon's tongue can be longer than its body. It shoots out at lightning speed - faster than a human eye can follow - and catches prey with a sticky tip. The entire strike takes less than a second!
Large monitors are fierce predators! Komodo Dragons hunt deer, pigs, and even water buffalo! They have venomous bites and powerful jaws. After biting prey, they follow it until venom and bacteria cause the animal to weaken.
Green iguanas are vegetarians! Adult green iguanas eat mostly leaves, flowers, and fruits. Having a diet of tough plants requires a long digestive system and special bacteria in their guts to break down plant material.
Some lizards barely drink water! Desert lizards like horned lizards get most water from their food. Others, like Thorny Devils, collect morning dew on their skin. The water channels to their mouths through tiny grooves between scales!
