Clouded boa is native to island of Dominica in the Lesser Antilles. Since these insular population is isolated, not able to share genes with other forms of the species, furthermore it is distinct in appearance, Dominican boas are often considered as a separate species, Boa nebulosa by herpetologists.
Basic coloration is relatively dark, brownish toned. Number of blurred saddle patterns is high, usually between 32-35. Ventral is grayish with lot of black speckles. Just like in case of most Boa constrictors, juveniles are much lighter in coloration than adults and have more prominent patterns. As the animals are getting older, their primary colors become darker, saddles will be much less distinct. Patterns on the head are also getting dim by age. The spear shaped pattern on the top of the head is- similarly to Boa c. orophias -often splited.
Biggest females can grow as long as 2,5 m (more than 8 ft), males are much smaller and slender.
According to Lazzel's observations, clouded boas tend to den up in various hidding places, caverns, undercuts in their habitat. Sometimes as many as 10 specimens can be found in such hideaways. This behaviour is not fully understood. It seems boas in Dominica are using the volcanic activity of the island as a radiator, what's more they are supposed to spend most of their life in these hiding areas. They only leave these places for hunting and drinking. Their main preys are rats, opossums, maybe agoutis, but they won't refuse fowls found by house of farmers, either.
Boa c. nebulosa are very seldom in captivity, thus their price is too expenisve for most boa enthusiasts. To the best of our knowledge, Klaus Bonny and Hermann Stoeckl are the only successful breeders in Europe.
