Brazilian redtail boas are rarely kept boids. Brazil banned export of wild animals several years ago, making it difficult for this locality to spread among snake enthusiasts. Ancestors of most specimens kept these days, came from Belem and were imported from South America's biggest country in the 1980ies. There also exist a locality known as "North Brazilian" in captivity.
Young animals are usually light colored, therefore they are nicknamed as "white Brazilians " sometimes. Although they turn more yellowish, cream colored later, they will not loose their attractive appearance. Patterns will also have more contrast by time.
Brazilian redtails tend to have flows, shades between the dorsal blotches (saddles), which is typical for this locality. They rarely reach more than 2,5m (8+ ft), however a 3,5m (12 ft) long specimen have been reported.
They should be fed moderately to avoid regurgitation. Nonetheless, moderate fed boas are problem free, solid bodied, easy to handle. Breeding them is much more difficult however. Successful breeding is achieved by proper stimulations only.
Boa c. constrictor and Boa c. amarali are both native to Brazil. As there are no true barriers between these two, there is a transitional form occuring in Central Brazil towards to costal region. Some taxonomists consider them as a separate subspecies.
