The green basilisk lizard is also called a plumed or double-crested basilisk; but its amazing ability to run on water gives this species its most recognizable moniker: the Jesus Christ lizard.

DescripciĆ³n
DescripciĆ³n cientĆfica
Como todos los miembros del gĆ©nero, estas lagartijas poseen pĆ”rpados mĆ³viles; escamas ventrales levemente quilladas; cabeza cubierta por escamas apenas agrandadas; laminillas subdigitales angostas y quilladas; piegue gular y cresta dorsal. No tienen poros femorales. La escama interparietal es pequeƱa, de tamaƱo semejante al de las escamas vecinas y menor que la abertura Ć³ptica. Las escamas supraciliares no se traslapan. Presentan un fleco escamoso en los tres dedos exteriores. La cola tiene una cresta medianera. Se caracterizan por poseer grandes crestas en la cabeza, tronco y cola (ver imagen de cabeza). Estas crestas estĆ”n sostenidas por proyecciones Ć³seas del crĆ”neo y por vĆ©rtebras.
ComĆŗnmente alcanzan los 60 mm. de longitud, pero pueden llegar a medir hasta un metro, del cual la cola ocupa 2/3 partes. Pesan hasta 600 gr. Las hembras son mĆ”s pequeƱas, la cresta en ellas es muy reducida y sĆ³lo cubre la cabeza. Alcanzan aproximadamente la mitad del volumen de los machos. Estas lagartijas tienen la capacidad de caminar sobre el agua, por lo que a veces se les llama lagartijas Jesucristo. Esta habilidad se debe a la presencia de pliegues de la piel a lo largo de los dĆgitos, que al hacer contacto con el agua se abren como alerones y permiten que, por fracciones de segundo, el peso de la lagartija se sostenga sobre la superficie del agua. TambiĆ©n tienen la caracterĆstica de ser bĆpedas facultativas, pues cuando corren levantan la mitad anterior del cuerpo, de manera que terminan corriendo sobre las patas traseras.
B. plumifrons es de color verde esmeralda y tiene muchos puntos azul marino a lo largo del cuerpo; de los costados hacia el vientre y la papada el color verde gradualmente cambia a amarillo. La hembra es similar, pero no presenta gran desarrollo de la cresta.

On Saturday, June 27, 2009, thunderstorms were in the area and Wakodahatchee Wetlands were void of people and the Basilisk were enjoying a day of chasing each other. There were two pair, obviously trying to mate. Thes lizards actually stand on their back legs to run and it was an experience to watch them play, even though I could never get a photo of them running....just too fast. They also have the ability to run on top of the water, giving them the name "Jesus Christ Lizard". This is the female, the male can be identified by it's crown.
They are generally found in Latin America anywhere there is a body of water (usually from Central Mexico to Ecuador), and recently they have been introduced to Florida.

For close-up shots and to provide Daniel Radcliffe with something practical and ārealā to battle in Harry Potter and the Chamber of Secrets, the Creature Shop built this Basilisk head with moving eyes, nostrils and mouth. For full body Basilisk shots, the Visual Effects Department crafted a computer-generated version that could move more fluidly and violently than the animatronic one.
Fast running lizard from central africa, but took this shot in London Zoo.

This one was catching the last of the sun before the afternoon became very overcast and wet. Seen near the lodge.
