Im extremley interested in purchasing a Red Tailed Boa Constrictor.... Ive had one before (got sold because of great offer for the quality of the specimen) and know everything about care for them and am able to get a custom enclosure for it when its older so dont worry about that... But anyway, when i was in my local reptile shop (D&J Reptiles) i saw a red tailed boa, and its head was huge fore its actual size.... Is there a specific red tail (suriname,guyana,colombian,etc.) thats head gets bigger faster then most? The snake must have been a female, so does the gender have a role in how big they get, like do they get bigger faster if they are females, and are their heads bigger? I know that females get bigger then males by quite a bit, but do they grow bigger faster? I also know that all snakes have different growth rates, but in general, do females grow bigger than males faster??

Thankyou,
Brandon
