The Basciliscus basciliscus inhabits the rainforests of Honduras, Nicaragua, Costa Rica, Panama and North-West Columbia at the Pacific side. You will find them mostly in trees, bushes, rocks, logs and riverbanks. Contrary to the Basiliscus plumifrons, you see the Basiliscus basiliscus mostly at sunny spots, enjoying the sun. Although the Basiliscus basiliscus can run away at his hind legs, across the water like the Basiliscus plumifrons, he mostly runs high into the trees than across the water or diving into the water. But they also can cross the water for quite some distance, like they run over land. A narrow seam of skin, which runs around each toe, forms a moveable flap that is expanded when its foot is pressed onto the water, thus creating a larger surface area. The force that the basilisk puts into the downward movement of its foot, produces an upward pressure that keeps him from sinking. When the basilisk presses its foot down onto the water, an air-filled pocket is formed around the foot. This pocket quickly fills with water, so the basilisk must rapidly withdraw its foot to prevent from having to ‘plough’ through the water. As the foot retracts, the moveable skin-flaps on the toes fold down against the sides of the toes to reduce friction against the air. This combined pressure allows the basilisk to run on water with a speed of 8 to 10 km an hour. Young bascilisks can run larger distances on the water before sinking. This ability gave them the name of Jesus Christ lizards.
Also contrary to the Basiliscus plumifrons you see the Basiliscus basiliscus often at large numbers together, sometimes up to 400 per hectare. Nevertheless the males have a real territorial urge, you can see this from the many damaged head crests, due to seriously fights.
Mostly you see the basilisks in the lowlands until an altitude of 800 m.
