Guyana Red-tailed boa constrictors get their popularity from their sticking colors. Be careful because they can often be confused with the common boas. The main difference to distinguish them is that Red-tailed boas are typically heavier bodied, longer and their markings are quite bold. They reach eight to ten feet and live up to thirty years. We can honestly say that this guy is the calmest snake we have ever come across. If you have any questions, please reach out.
