The plumed basilisk (Basiliscus plumifrons), also called commonly the green basilisk, the double crested basilisk, or the Jesus Christ lizard, is a species of lizard in the family Corytophanidae. The species is native to Central America.
The plumed basilisk is the largest basilisk species, with an average snout-to-vent length (SVL) of approximately 10 inches (25 cm). Including the tail, it can reach 3 feet (91 cm) in total length. Adults are brilliant green, with bright yellow eyes, and small bluish spots along the dorsal ridge. Males have three crests: one on the head, one on the back, and one on the tail, while females only have the head crest. Juveniles are less conspicuously colored, and lack the characteristic crests.
