Plumed Basilisk

Looks how to spot one

scales

The plumed basilisk is a slender, bright green to blue-green lizard with a compressed body and a long, flattened tail. The back is covered in small, granular scales, while the belly scales are smooth. Adult males sport three prominent crests: one tall, bony crest on the head, a smaller one along the back, and another on the tail. Females have smaller or absent crests and may keep some of the juvenile banded pattern. The eyes are bright yellow, and the underside is paler green.214

Personality what they are like

Plumed basilisks are naturally shy, reactive and flighty, relying on speed and water-running to escape threats. They are not handleable pets; they stress easily, especially if wild-caught. Captive-bred individuals may become calmer but still prefer to observe from a distance. They are territorial, especially males, and need plenty of hiding places to feel secure. These lizards are best suited for experienced keepers who enjoy watching active, display-oriented animals.541

Daily activity how busy a day looks

Plumed basilisks are diurnal and very active, needing a large, vertically oriented enclosure with plenty of climbing branches, dense foliage and a big water area. They require a warm basking spot (up to 40°C) and UVB lighting. The enclosure should be at least 200 x 150 x 230 cm for a pair, or larger for a group. Humidity should be kept high (70-100%) with good ventilation.416

Grooming and care the hands-on bits

These lizards need a clean, well-maintained rainforest terrarium. Misting regularly is essential to maintain humidity, but ventilation must prevent mould. The water basin must be kept clean and deep enough for swimming. Snout injuries from glass or mesh can occur; inspection and gentle handling are required. Supplement food with calcium and vitamin D3, especially if UVB is limited.54

Home where they are happiest

Plumed basilisks need a large, tall rainforest terrarium with many climbing branches, thick plants, cork tubes, and a water basin at least 12-13 cm deep. Daytime temperature: 25-30°C, basking spot up to 40°C, nighttime 20-22°C. Humidity 70-100%. UVB lighting is essential. They do not hibernate. An outdoor enclosure with natural sunlight is beneficial, but air circulation must be good. They are not venomous and are not illegal to keep in most countries, but always check local regulations.413

Food basics what goes in the bowl

Plumed basilisks are omnivorous but mainly eat animal food in captivity. Their diet should include a variety of insects: crickets, grasshoppers, roaches, superworms, waxworms, and silkworms. They also accept small vertebrates like pinky mice, small freshwater fish, and occasionally small chicks. Fruit (bananas, berries) and vegetables (collards, dandelion) can be offered in moderation. Insects should be gut-loaded and dusted with calcium and vitamin supplements.154

Company who they like around

Plumed basilisks are territorial. Only one male should be kept per enclosure, as males fight aggressively. They can be kept in pairs or groups of one male with several females. They do not enjoy handling and are best observed rather than touched. A calm environment with retreat options reduces stress. They are not suitable for noisy households or homes with small children who might disturb them.541

The story where it all began

The plumed basilisk has always been admired in its native Central American rainforests for its striking green colour and its remarkable ability to run on water, earning it the nickname 'Jesus Christ lizard'. It was first described scientifically in the 19th century. As a pet, its popularity grew along with the interest in exotic reptiles in the late 20th century, though it remains less common than some other lizards due to its demanding space and humidity requirements. Wild-caught individuals are often too nervous to thrive, so captive-bred animals are strongly recommended and are becoming more available from specialised breeders.251
