Boa constrictors, whole or in parts, are also seen in local markets within their range, presumably as food or medicine. movements of a hard surface that are produced by animals as signals to others. The type locality given is "Indiis"a mistake, according to Peters and Orejas-Miranda (1970). As such, female boas in inadequate physical condition are unlikely to attempt to mate, or to produce viable young if they do mate. Habitat Boa constrictors can be found in different habitats including rainforests, agricultural areas and deserts in trees or on the ground. Furthermore, females likely become reproductive only when they are in good physical condition. Once the prey is dead, the snake swallows it whole. [38] The female then sheds two to three weeks after ovulation, in what is known as a post-ovulation shed which lasts another 23 weeks, which is longer than a normal shed.
