Boa constrictor
The boa constrictor (often called the common boa or red-tailed boa) is a large, impressive snake that appeals to keepers ready to step up from beginner colubrids to something more substantial. Native to Central and South America, boas are heavy-bodied constrictors that typically reach 6-10 feet with females being larger, though some localities and individuals can exceed this. Despite their size, boa constrictors are generally docile with excellent temperaments, and captive-bred specimens are usually calm and handleable. They are notably more intelligent and interactive than many snake species, often displaying clear recognition of their keepers. Boas are long-lived at 20-30+ years, give live birth instead of laying eggs, and come in various locality forms and morphs.
