    Venezuelan redtail boa (Boa c. constrictor)

    Venezuela is a huge country, with several different geographic areas, including savannas, swampy and moorish lowlands, rainforests that boas had adapted to very well.
    As the habitat changes, so does the appearance of redtail boas. In addition, according to the latest field studies, in North-West Venezuela a transitional form of subspecies constrictor and imperator does occur, which has characteristics from both subspecies.

    Specimens found in Paraguaná Peninsula, Western-Venezuela resemble to imperator from Central America. Some taxonomists claim that this taxon deserves a separate subspecies status, others consider them as an insular form of imperator. Anyhow, Paraguaná boas do differ from Venezuelan redtail boas (Boa c. constrictor) in appearance, as well as scale counts that are used to determine subspecies.

    Animals in Caracas area- including some insular regions -are much more similar to Boa c. constrictor, although they lack the typical bright, shining red tail. They tend to have light grey basic coloration as a juvenile, which turns into brownish as they mature. Their saddle patterns are dark brown, as their tail markings are, as well.

    Finally, boas from East-, South- and South-West Venezuela are true redtail boas. Basic coloration is light, patterns are distinct with lot of contrast, tails are bright red, similarly to Suriname and Guyanan redtail boas.

    Since the local laws strictly prohibit the animal trade, this locality have not been common in captivity. Fortunately, hard worker Boa keepers like Gus Rentfro and Dennis Sargent have produced top quality litters from both Paraguaná boas and redtail boas.
    In our experience, juveniles accept proper sized rodents without any problems. Regurgitation syndrome is uncommon. However, their growing rate seems to be slower than other redtail boas.
