The Green Basilisk: Costa Rica’s Enchanting “Jesus Christ Lizard”
Costa Rica is home to some of the most fascinating creatures on Earth, and among them is the remarkable Green Basilisk (Basiliscus plumifrons). Known for its ability to run across water, this striking lizard has captivated nature lovers and wildlife enthusiasts.
Let’s explore 10 incredible facts about the Green Basilisk and why it thrives in Costa Rica’s lush rainforests.

1. It Can Run on Water
The Green Basilisk has an astonishing ability. It can run on water, earning it the nickname “Jesus Christ Lizard.” It uses its fringed toes and rapid movements. These actions create air pockets beneath its feet. This allows it to sprint across the surface before sinking.
2. A Master of Camouflage
With its vivid green coloration and blue speckles, the Green Basilisk blends seamlessly into the dense rainforest vegetation. This natural camouflage helps it evade predators like snakes and birds of prey.
3. Found in Costa Rica’s Rainforests
The Green Basilisk thrives in Costa Rica’s humid lowland forests. It is often found near rivers and streams. In these areas, it can quickly escape danger by diving into the water.
4. Males Have Impressive Crests
Male Basilisks boast three prominent crests—on their head, back, and tail. These crests are used for attracting mates and intimidating rivals.
5. Expert Swimmers and Climbers
In addition to its water-walking abilities, the Green Basilisk is an excellent swimmer and climber. It can remain submerged for up to 30 minutes to avoid predators.
6. A Diet of Opportunity
Jesus Christ Lizards are omnivorous, feeding on a variety of foods, including insects, small vertebrates, flowers, and fruits.
7. Speedy Escapes
When threatened, the Green Basilisk can run at speeds of up to 7 mph (11 km/h) on land. It can also run across water. This ability makes it one of the fastest reptiles in its habitat.
8. Female Basilisks Lay Many Eggs
Females lay up to 20 eggs per clutch, burying them in warm, moist soil. The eggs hatch in about two to three months, and the baby lizards are fully independent from birth.
9. A Unique Defense Mechanism
Aside from running and swimming, these lizards can freeze in place to avoid detection by predators. Their stillness and camouflage make them nearly invisible.
10. A Symbol of Costa Rica’s Biodiversity
The Green Basilisk is part of Costa Rica’s diverse ecosystem. It plays a crucial role in maintaining the natural balance of the rainforest.
