How big is a teenage boa constrictor?

Answer 1

Significantly smaller than anacondas, boas can grow up to 13 feet long and weigh more than 100 pounds. Boas are about 2 feet long when they are born and grow continually throughout their 25 to 30-year lifespan. A teenage boa is about 4-6 feet weighing about 45 pounds

First off, most boas are not going to get 13 ft. An anaconda will commonly get larger than that, though. A boa constrictor female is normally 8-10 ft, occasionally getting as big as 12 ft. This is usually due to power feeding and shortens the snake's lifespan. Their first year, BCC's (Boa constrictor constricor aka the "true" red tails) will reach 3-4 ft. BCI's (Boa constrictor imperator) will reach 6-7 ft their first year. This is because BCC's cannot handle as large of meals as BCI's, so grow slow but get longer. A boa constrictor should reach sexual maturity at 4-5 years old.
