I'm not sure with carpets, but the videos I see of the snake catchers in Australia sure make me think they get pretty large in the wild.

Carpets, specifically coastal carpets have adapted very well to human encroachment. It seems the areas around homes provide a host of prey opportunities be it wild animals, or domestic dogs and cats.

They certainly seem large when the snake catchers show up.

The most beautiful boa I've seen is wrapped around somebody's leg in Vin Russo's book.

Huge and solid as rock. It was a Suri I believe.

I don't expect my female coastal to get much larger, yet she surprised me this last year with a growth spurt at 6 years old and now she's 7.

She's not a predictable eater, I typically try once a month these days but she goes longer too.

I'm reasonably confident I know the photo you are talking about, it was a friend of Gus R in the photo with his hands on the neck of a huge female boa.

You guys covered male combat and some other stuff so I'm going back to an earlier comment I made about 'big snakes eat big meals'. Gus R. talked about raising many boas to 8 feet on rats, but the ones that he raised to greater lengths required larger prey. It didn't have anything to do with nutrition, maybe something to do with calories but I don't think it was the amount of calories over the period of a year but the amount of calories per meal that did 'something'. A mature female BCO here grew more (length) on just 3 meals of 4+ pound rabbits in a year than the previous two years on rats. I've see similar results with other boa. IMO large meals activate something in their genes triggering growth.

I know my buddy Gio has this thread in Carpets but I know boas so I have to relate those observations and if he doesn't like it on his thread, too bad! Friend .

You always hear Suriname Guyana boa keepers talk about feeding mice the first year, not feeding too often, not feeding too large, etc...and its all true but how is it the largest bc on the planet are such slow starters? And how is it that even a 9-10 foot captive born Suriname/Guyana boa is very rare (let alone something really big)? Something happens to boas as they age and granted genetics are a factor as an individual boa, differences in other subs of boas (when the BCO were young in my care they could eat meals with ease that I wouldn't feed to a much larger non adult Suriname boa) and even location within a sub is a factor (I don't believe a Pokigron Suriname boa will reach the size of some of the Suriname boas brought into the country 35-40 years ago). As a boa matures they are more capable of eating large meals. As keepers most say meal size should be equal to their body width -a good practice for sure but mature boas thrive when going beyond this size guideline and can swallow larger prey with an ease they didn't have when they were younger. A mature 7 foot Pokigron Suriname eats rabbits over 2 pounds with ease but I never would have fed a meal as large (relative to size) when it was a younger snake.

I think males in some boa subs (areas of location) have the potential to reach large sizes but they don't. Import houses get in really big females once in a while but I've never heard of males that compare...why is that? I have a theory. As I said above, large meals trigger growth and as they mature they are capable of eating much larger prey as compared to percentage of body mass than when they were younger. That pertains to sex because the female boa is desperate after giving birth, eating anything she can fit in her pie hole that she crosses paths with and she is spending way more time looking for things to cross her path than a male. This combined with luck and years of being successful lead to a large female snake. Mature males in captivity (and I'd bet are similar in the wild) are about conserving resources (they are lazy). They hunt less and require much less food. Even non breeding females are wanting to be fed more than males in captivity.

Breeders may never noticed the ability for prey size increase in mature boas as it doesn't matter to them and I think other keepers who have observed it don't talk about it because they don't want to influence a keeper into doing something that is outside of their 'range'. I hesitate to post some of this food size 'stuff' because I don't want someone with a limited understanding to kill their boa. It is an absolute fact that increased calorie intake in a young boa will not give you a large, old boa and overfeeding an adult boa will only get you a fat adult...like my buddy Gio quoting Gus...the largest boas are the oldest.
