The Basilisks Basiliscus sp.
Description: Also known as Crested basilisk, Double-crested basilisk, Plumed basilisk and Jesus Christ lizard (because they can run on top of the water). The four known species of this spectacular lizard are distributed from tropical southern Mexico to the northwestern coast of Ecuador. They mainly live in trees near rivers or other bodies of water where they can escape danger by jumping in, running across the surface, swimming away or hiding underwater. They may also be found on top of rocks and dead logs. Males look a bit prehistoric with dinosaur-like crests on the head and back. The largest males can reach over 32" in length, much of which is the tail. They can live for an average of 14 to17 years and have been known to live for up to 20 years. Most available basilisks are wild caught or imported from reptile farms and may be skittish and difficult to handle. With patience and the proper care they will adjust to captivity and settle down. Their care is similar to that of Water dragons. Males are highly territorial and must not be kept together in the same enclosure or they will fight. They display head bobbing to threaten each other and also when courting females. Species: Temperature: Daytime – 75 to 85°F with a basking site near 95°F. A few degrees cooler at night is beneficial. A temperature gradient throughout the enclosure is preferred. Humidity: Around 60 to 80% with frequent misting. Seasonal variations should occur. Lighting: UV lighting is required, the 5.0 fluorescent type will also supply the light to grow some plants. A basking light is also needed. Use a timer to provide a consistent 12-hour day during the summer. Feeding: Somewhat omnivorous, especially when young. Crickets and mealworms are fine as a staple diet but a variety of other insects should be offered. Earthworms, snails, goldfish and pinkie mice, etc. can be offered too. They also eat some vegetables, fruits and seeds. Basilisks become more predatory as adults. A good vitamin/mineral supplement should be given at least twice a week for adults and more often for young, growing lizards. A bowl of clean water large enough to fully submerge in should be available at all times. A water feature large enough to swim in would be even better. They may use it for a toilet so it will need to be cleaned often. Habitat: These are very active lizards, at least a 55-gallon tank with a secure, ventilated lid is needed for a pair and at least a 75-gallon for a larger group, a tall tank is best. Set it up as an arboreal forest or jungle habitat with sturdy plants and plenty of climbing branches. Be sure to provide a basking spot, thick branches work well. Keep the substrate somewhat moist but not soggy. A water dish large enough to completely submerge in is good, but a water feature large enough to swim in is the best. Breeding: Always start with healthy animals, 1 male with 2 or more females seems to work best. Outdoor breeding works a little better than it does indoors. Cycle the breeders for 2 to 3 months beforehand by keeping the temperatures and humidity in the low range with a day length of about 10 hours. Then gradually bring these environmental factors up to the high range with a 12 to 14 hour day length. This should induce breeding behavior, demonstrated with much head bobbing by the male as he courts the females. If a female is receptive, she will allow him to copulate with her multiple times. Gravid females will become noticeably heavier over the next couple of weeks and will need a place to lay eggs during the third week. A suitable egg-laying medium, such as potting soil mixed with sand, should be available to her, either as part of the substrate or in a separate container. She will dig a nest and test for the proper temperature using a receptor in her nose. When everything is to her liking, she will lay the eggs and bury them. Up to 4 or 5 clutches may be laid per season. |
