From Gliding to Blood-Squirting: Extraordinary lizards redefine reptile world

From Gliding to Blood-Squirting: Extraordinary lizards redefine reptile world

 

By Abbas Nazil

When most people think of lizards, what comes to mind is a small, green, wall-climbing creature found in warm climates. But lizards are far more diverse and fascinating than commonly imagined.

A look across different species reveals an astonishing range of behaviors and adaptations—from gliding through the air and running on water to squiring blood from their eyes.

These traits not only challenge traditional views of lizards but also highlight the complexity and evolutionary brilliance of reptiles.

Among the most dramatic examples is the Frilled Dragon (Chlamydosaurus kingii), known for its startling neck frill that flares when threatened.

Capable of running on two legs, it inhabits northern Australia and Papua New Guinea and is currently listed as Least Concern.

Similarly eye-catching is the Plumed Basilisk (Basiliscus plumifrons)—nicknamed the “Jesus Christ lizard” for its ability to run on water.

Using speed, lightweight bodies, and splayed toes, they escape predators by dashing across river surfaces in Central American rainforests.

The Common Flying Dragon (Draco volans) glides from tree to tree using wing-like skin flaps, while the Komodo Dragon (Varanus komodoensis), the largest lizard species, dominates with brute strength, deadly bacteria-laced saliva, and the capacity to consume up to 80 percent of its body weight.

Found on a handful of Indonesian islands, the Komodo Dragon is currently classified as Vulnerable.

On the opposite end of the size spectrum is the Virgin Islands Dwarf Gecko (Sphaerodactylus parthenopion)—the world’s smallest lizard at just 1.6 cm in length.

Not much is known about this rare species, which is endangered and limited to the British Virgin Islands.

In Madagascar, the Eyelash Leaf-Tailed Gecko (Uroplatus phantasticus) blends almost seamlessly with dry leaves, boasting exceptional camouflage. Its flat body, tail, and skin veins mimic foliage with uncanny precision.

Meanwhile, in Ecuador’s misty cloud forests, the once-thought-extinct Pinocchio Lizard (Anolis proboscis) returned from obscurity in 2004, complete with a comically long snout whose purpose remains a mystery.

Desert-dwelling species also reveal unique traits. The Thorny Devil (Moloch horridus) sports a spiky armor that collects rainwater, while the Regal Horned Lizard (Phrynosoma solare) famously squirts blood from its eyes as a defense mechanism.

The Armadillo Lizard (Ouroborus cataphractus) rolls into a spiny ball, while the venomous Gila Monster (Heloderma suspectum) delivers one of the few medically significant lizard bites—though never fatal to humans.

Even more marine-adapted is the Marine Iguana (Amblyrhynchus cristatus) of the Galapagos Islands—the only lizard known to forage underwater, diving up to 20 meters to graze algae.

Also striking is the Slow Worm (Anguis fragilis), a legless lizard often mistaken for a snake, found across Europe and Russia.

Then there’s Jackson’s Chameleon (Trioceros jacksonii), which sports three horns and exhibits all the hallmark chameleon abilities—color change, panoramic vision, and a projectile tongue.

The Green Anole (Anolis carolinensis) may seem ordinary, but its extendable pink dewlap used in communication reveals hidden complexity.

From deserts and forests to islands and mountaintops, these reptiles have evolved extraordinary survival strategies, demonstrating that the world of lizards is anything but ordinary.

Their diverse appearances, behaviors, and abilities continue to fascinate biologists and nature lovers alike, proving that evolution has no shortage of creativity when it comes to reptiles.
