However, due to how body size may vary widely between individual snakes, there is no clear data on each sex’s precise lengths. (Source: Oxford Academic ) Boa Constrictor Size: Female Boas Get Larger Than Malesįemale boa constrictors are usually larger than males in both mainland and island boa populations. Though this is uncommon with most animal species, it is very common with snakes.įemale boa constrictors and pythons are grow to larger sizes than males.

The unique ecological pressures they experience on these islands versus the mainland seem to play a direct role in the size differences between these snakes and the average boa. Scientists have recorded wild populations on Central American islands where these dwarf varieties live, noting that different physical features and growth patterns characterize them. Island form red-tailed boas tend to be smaller than others, often falling below two meters long (over 6.5 feet). Normally, you can expect a red-tailed boa to grow between 2-3 meters (6.5-10 feet) in length, with exceptions and variations known as “island forms.” Still, its size is nothing to sneeze at: The maximum length ever recorded for a red-tailed boa just exceeded four meters (more than 13 feet) – larger than two fully grown men! However, not all boas get this large. This snake is relatively modestly sized when compared to other large species like reticulated pythons and anacondas. Part of what draws so many people to this breathtaking creature is its size.Īdmittedly though, the boa’s size has been slightly exaggerated by enthusiasts around the world. Red-tailed boas, more formally known by their scientific name Boa constrictor, are beautiful, formidable animals. How Big Boa Constrictors Get In Captivity? To determine whether this is the right species for you (and provide it with the best possible care), you’ll need a realistic idea of what to expect in their growth.

That said, these snakes are not necessarily small either. Luckily, this snake’s size is largely exaggerated. When most people imagine boa constrictors, they envision a massive serpent that they may not be able to control and handle past maturity. Still, sizes may vary widely, as their environment and feeding routine directly influence their size.

Their average weight normally falls between 60-100 lbs. Red-tailed boas or common boas typically grow up to about 2-3 meters in length, with females usually growing larger than males. After all, it is important to understand how big boa constrictors can get before purchasing one. Though their are many types of boa constrictors of various size, we are going to focus on the common boa or red tailed boa. Boa constrictors are one of the most popular pet snakes and are known for their large size and beautiful patterns.
