Costa Rica is home to some of the most unique wildlife on the planet. From scarlet macaws to sloths and monkeys, every corner of the rainforest reveals something fascinating. Yet one creature manages to stand out even among this rich biodiversity—the Jesus Christ lizard. Officially known as the green basilisk (Basiliscus basiliscus), this reptile has earned international fame for its jaw-dropping ability to run across water.
For travelers seeking unforgettable wildlife encounters, spotting a Jesus Christ lizard in Costa Rica is a true highlight. Let’s explore the facts, science, and best ways to see this remarkable animal in its natural habitat.
The Legendary “Jesus Christ Lizard” of Costa Rica
The nickname “Jesus Christ lizard” comes from the basilisk’s almost miraculous escape strategy. When threatened, it can sprint upright across the surface of rivers and streams, leaving onlookers stunned. This incredible feat has made it one of Costa Rica’s most talked-about rainforest residents.
Costa Rica, which protects over 25% of its land through national parks and reserves, provides the perfect environment for these lizards. They thrive in the country’s lush lowland forests, often near rivers where their dramatic water-walking skills come into play.
Meet the Basilisk: Facts & Features
- Scientific name: Basiliscus basiliscus
- Family: Corytophanidae (the casquehead lizards)
- Size: Males can reach up to 3 feet in length, including their long tail. Females are generally smaller.
- Color: Vibrant green with yellow stripes and crests on the head, back, and tail.
One of the basilisk’s most striking features is its crest, which resembles a dragon-like crown. Males boast larger crests, used for display and territorial dominance. Their long toes are fringed with flaps of skin that spread out on water, creating tiny air pockets—an essential adaptation for water-walking.
These lizards are diurnal, meaning they are most active during the day. You’re most likely to spot them basking in the sun on low branches or darting through the underbrush when startled.
The Water-Walking Wonder
The Jesus Christ lizard’s ability to run across water is not magic—it’s physics and biology combined. When fleeing predators such as snakes, birds, or mammals, the basilisk uses its powerful hind legs to slap the water surface at high speed. The flaps of skin on its toes increase surface area, giving just enough lift to keep the lizard above water for several meters.
- Juveniles are lighter and can run longer distances across water, sometimes up to 15 feet.
- Adults are heavier and may only manage a few strides before splashing in and swimming.
Even when they eventually sink, they remain excellent swimmers and divers, staying underwater for up to 30 minutes if needed. This dual strategy makes them one of the rainforest’s most adaptable reptiles.
Habitat & Where to Spot Them in Costa Rica
Jesus Christ lizards prefer humid, lowland environments with rivers, streams, and dense vegetation. You’ll often see them perched near water, ready to dash at the first sign of danger.
Some of the best places to encounter them in Costa Rica include:
- Manuel Antonio National Park (Pacific coast)
- Tortuguero National Park (Caribbean side)
- Corcovado National Park (Osa Peninsula)
- Sarapiquí region (Northern lowlands)
If spotting wildlife is a priority on your trip, consider joining a professional nature tour. For example, you can check out this Manuel Antonio Park Guided Tour: See Wildlife Up Close where expert guides help you spot lizards, monkeys, and sloths hidden in the rainforest canopy.
What Do Jesus Christ Lizards Eat?
The basilisk is an omnivore, meaning its diet is varied and opportunistic. These lizards eat:
- Insects (their main source of protein)
- Small fish and crustaceans
- Fruits, flowers, and leaves
This flexible diet allows them to thrive in diverse habitats. In the ecosystem, they play an important role in controlling insect populations and providing prey for larger predators.
Wildlife Encounters: From Forest Trails to Guided Tours
For travelers, spotting a basilisk is often an unforgettable highlight. Unlike shy reptiles that hide away, Jesus Christ lizards can be quite visible, especially around riverbanks. They often remain motionless until disturbed, then dash across water—an exhilarating sight for any nature lover.
Guides in Costa Rica are trained to spot even the smallest movements in the forest. With their help, you’ll have a far better chance of seeing not just basilisks but also monkeys, toucans, sloths, and even rare species like tamanduas.

Cultural & Local Significance
The basilisk has become a favorite among travelers, photographers, and local guides. Costa Ricans often highlight it on tours because visitors are fascinated by its biblical nickname and spectacular running ability.
Compared to larger reptiles like iguanas or caimans, the Jesus Christ lizard has a playful, almost magical reputation. Its ability to “walk on water” makes it one of the most memorable animals to share with children and first-time visitors.
Protecting Costa Rica’s Rainforest Creatures
The Jesus Christ lizard itself is not currently endangered, but its survival depends on healthy rainforest ecosystems. Deforestation, pollution, and habitat fragmentation threaten the waterways it depends on.
Costa Rica is a global leader in conservation, with strict protections for wildlife and ecosystems. As a traveler, you can support this by:
- Choosing sustainable tour operators.
- Respecting park rules and staying on trails.
- Avoiding single-use plastics that pollute rivers and coasts.
