The Common Basilisk (Basiliscus basiliscus) is a lizard found in Central and South American rainforests near rivers and streams… [they] take the nickname the "Jesus Christ Lizard" or "Jesus Lizard" because when fleeing from predators, they gather sufficient momentum to run across the water for a brief distance while holding most of their body out of the water.
The children spotted this Jesus Christ Lizard off the path to the beach in Manuel Antonio National Park.
