Does anybody know what the world record RTB is? Or if not, what is the largest you've heard of personally? I'm mainly wanting to hear length. Reason be is there was an ad in our local paper saying they had a 12 foot RTB and were asking $1,500. I've never studied boas like I have other species, but I've only heard of them topping out at around 9foot, maybe close to 10, but definately not 12. Anyway, if anybody could help, I'd appreciate it.

Acording to John C.Murphy and Robert W. Henderson's book Tales of giant snakes it's 16ft.I believe there are many other accounts around that length.I've had several reach close to 9ft.Thats BCI

I'm not a big fan of big snakes because they get expansive to house and feeded but they are cool display animals and big redtails are way cooler then big burms imo. that being said one of the local shops here has a massive female bci at 8.5 feet and 65 lbs. she is way over weight and they have been trying to thin her out but shes still big. but one of my friends does have a female BCC she got from meade back in the day i thinks its a amazon basin. it's not fat in any way i dont now ho much she weighs but she dwarfs the fat bci at 14 feet in length and a head like a dinner plate.

Thats pretty darn big.

13ft Suri that was so big I got a little scared! He was feeding her and I stayed out after I saw it! This boa could take me down and I weigh 215lbs! Atleast she looked like she could no problem! Thats the biggest and scaryest boa i've ever seen! I think he got it in Daytona in 2004, so if you saw her you'd know!

of that one from Derek and she was around 11 ft. They were huge. Here is another one from that line that I used to have that was 10-11 ft. These snakes would be much bigger now if I still had them. If I recall, Louis Porras documented in one of the reptile magazines, that he personally unpacked a crate from Peru that contained two 15 plus and one 16 plus ft BCC when he worked for the Pet Farm back in 1970's. This is the biggest reliable report I have heard. The 18.5 ft boa from Trinidad was a Green Anaconda, not a BCC. I saw a photo of what was believed to be it in an old newspaper clipping when I was there on the island. I did get a baby female when I was there and I must say it did grow at an astounding rate. The largest I have personally seen was a 99 LB Peruvian about 15 yrs ago. I think it may have been around 13 ft because the head and tail would be on the ground when you held it across your shoulders. It had some serious black facial markings and an awesome red tail that you would not expect on one that old. It remains the most impressive BC I have seen yet. I used to talk with another guy from time to time during the mid 90's who was into huge Retics, Rocks, Burms, Anacondas and he had at two or three huge Colombian Boa Constrictors and at least two were over 100 lbs. I think he told me the largest was 120lbs. I do not know if they were Colombian BCC or BCI or crosses. I believe him because I saw in person one of his ARocks he sold and it was about 18ft (more than doubled the 8ft Neodsha cage) and about as thick as a telephone pole with no food in it and I was told it was one of his smaller ones.

Here's the largest I've ever seen. This was a gigantic female imported by me in the 1980's. It was around or a little over 14'. I believe Bcc sometimes reach lengths over 15'...TC

I've got one that's 10 feet and still growing. She's 13 years old now. About 65 lbs.

I spoke with Porras back in the late 80’s about those Peruvian imports by Bill Chase. Those Bcc’s were enormous, but many were never actually taped. He said the largest one was estimated at 16 feet, but never accurately measured. The largest Bcc that I am aware of that was actually accurately measured was right at 15 feet. I have not seen any records of Bcc that were taped at over 15 feet. Murphy and Henderson estimate that the record Bcc is somewhere between 15 and 16 feet, but don’t have any actual specimen data. From all the data I have seen, that is probably dead on. If anyone has any true measurement information on Bcc over 15 feet I would be most interested in seeing it. At least the size estimates and so-called measurements for Bcc are not near as wild as those seen for green anacondas. Thanks,

As far as longest Bcc goes -- Peruvians are considered to grow the longest, right? Then what -- Suriname, Trinidad, Venezuela, Guyana?

This Guyana female, was probably the largest overall in captivity and definately the longest when she died last year. I owned her and sold her too " constrictorsnorthwest. " She was measured at 13ft 9 inches. I have had some of the largest Peruvians, that most have seen over the years. In 1996, I bought a Peruvian from a guy named " Martin Novak. " He was from Alabama and had some of the largest Peruvian " males and females " that I had ever seen! They were absolute MONSTERS and the largest female that I had from him, was " 13ft and 5 inches. " She weighed 122 pounds, confirmed on my Vets scales! The female eventually died from being so big and was one more lesson in understanding that, that kind of weight and size, is impressive, but very hard on the Boa.She was the overall largest Boa that to this day, I have ever seen. Most Boa sizes, are way over exaggerated and a true 10ft Boa, is a large Boa and rare. I have seen pictures of so many, so called 15ft Boas and they make me laugh, when my old buddies show them too me. To think that some really cannot look at surroundings and get a grip on a Boas actuall size, is part of the proposed fiction. Anything over 12ft, is a genetic anomoly and the couple that I had and the very few others that I have seen, that were better than 13ft, were nothing less than freaks! Heads on them, tat looked like they could swallow a 10 pound rabbit, without much of a jaw stretch at all........John J

Just amazing ,I wish I could've seen some of those Boas listed throughout this thread.That Guyana you had John that would've been great to see her.Lar M

Boas By Klevitz

I started up this collection in '06. It's 90% Boa constrictors, but I do have a few Pythons and a few Colubrids just for variety.
I'm really noticing how much less I have to feed my Boas than the others. The others seem like they're starving in half the time. There is a lot to be said to not overfeeding a Boa constrictor.
