Water walking lizard: This lizard defies nature by running across water

The basilisk lizard, also called the “Jesus lizard,” or "water walking lizard" astonishes scientists. It can sprint across rivers and streams in rainforest habitats. Its speed and agility allow it to escape predators efficiently.

Natural Habitat

Basilisks are found in Central and South American rainforests. They prefer rivers, streams and wetland areas for hunting and escape. Rainforest environments provide abundant food and shelter for survival.

Science behind water walking skill

This lizard's specialised long toes with fringed scales create hydrodynamic lift underfoot. Rapid and bouncy strides generate temporary air pockets to support its weight. Lightweight body and tail motion stabilise the lizard during its sprint.

Evolutionary Advantage

Running on water helps basilisks reach food and territory quickly. Predators like snakes and birds are often outpaced by this water-running ability. This adaptation provides unique survival advantages in both aquatic and terrestrial habitats.

Physics Behind the Feat

High-speed motion and force distribution prevent the lizard from sinking. The combination of lift, speed, and surface tension enables its water-running capacity. Researchers study biomechanics to understand the precise coordination of limbs and tail.

Conservation and Awareness

Deforestation and habitat loss threaten natural environments, although basilisks are not endangered. Protecting riverine habitats ensures these lizards maintain their ecological niche. Scientists continue exploring biomechanics to inspire robotics and bio-inspired technologies.

Studying basilisks informs physics, evolution, and engineering applications worldwide. Nature’s innovations often provide lessons for human problem-solving and design.
