Our 2023 Argentine Boa Constrictors (Boa constrictor occidentalis) have been born! From parents Ladon & Hesperis, who are both pure OS line Argentines. Here’s a few photos I took (litter of 9, not all pictured).

Those guys are totally awesome! I love the pattern and coloring! How big will these guys get? I have a CA boa, 5 years old and he’s only around 5 feet
Congratulations @westridge!

Thanks. Argentines vary in size based on the line they are from. The adults that produced these babies are around 7 feet for the male and 8 feet for the female. However, that is just an estimate, they could be a little bigger. Both parents are are 11 years old, so they shouldn’t get much larger. I have seen other specimens that are significantly larger than that (10ft+). By contrast some lineages, such as Maxx Pink, do not usually exceed 6ft.

Precious babies! 
I absolutely adore Argentine boas. I think they’re some of the most beautiful boas out there. I love dark boas, and I also love the heads on Argentines. If they weren’t so pricey, I’d be seriously considering getting one. Heck, I’m considering it even with how pricey they are.
I’d love to see updates as they grow!

Hey Guys,
Old feedback but never too late for the truth. First on the size of the snakes. Maxx Pinks are not a morph, but selectively bred in a project starting in 1993. Further Maxx Pink project snakes have been the largest known BCO grown in captivity in recent decades with our breeders formerly being grown to 10’ and approx 45lbs. We’ve grown them to 65lbs and close to 11’. Further, regarding “pure OS line” The snakes you own were likely sired by a second gen Maxx Pink as my males were all he had for his last litters, which of course were many years ago. I’m quite familiar with OS having worked there and worked the adult BCO in 1991,1992. Very best wishes. For any interested I’ll be
Posting this post with pics of various 9-10’ Maxx Pink BCO. Please come check them out!

Thank you for this information, and at such convenient time as well! I just purchased a 2025 OS black line female - what exactly is OS, if you don’t mind me asking? And I always figured that Maxx Pink was a line bred trait, as I assumed with this black line. Is that true for that, as well?

Looking forward to seeing your adult pictures Bob. Don’t own any of these boas but I have always loved they way they look.
