Boa constrictor imperator
These boa come from a small island off the coast of Belize. They have a lot in common with the Caulker's Cay Boa. Not only do they both come from their respective cays off the coast of Belize but both are true dwarf boa and capable of breeding at a very small size. Both have evolved very unique survival adaptations that allow them to exist in less than ideal habitat for boa constrictors. However these two races of boa constrictor as represented in culture are also distinct from one another. The Crawl Cay boa have uniquely shaped heads. They also have a much less blocky dorsal saddle. Those Crawl Cay Boa in culture have shown us much more variation in morphology than the Caulkers Cay Boa has shown us. You can see some of this variation in my photos below. There are silver ones and brown ones as well as everything in between. They are usually heavily speckled boa and become more speckled with age. Aberrancies and striping in both the dorsal and tail saddles are rather common. The Crawl Cay boa can sometimes be a bit more nervous compared to the Caulkers Cay Boa as youngsters.
A person interested in these boa should spend some time studying the work of Dr. Boback. This is an easy exercise using the internet to take advantage of the availability of Dr Boback's work online. There is even an episode of the television show Snake Wranglers devoted to his work with the Belize Boa. Luckily for keepers of unique wild boa his work required bringing home a few boa to the US. The Crawl Cay boa in culture got a welcome injection of fresh blood thanks to some collaboration between Dr. Boback and Vin Russo. I have two lines of Crawl Cay Boa. One line is a nice silver Rio Bravo pair. The other pair were the result of pairing one of Dr. Boback's males with a female already in culture at Vin Russo's facility. I was one of the lucky ones to acquire a pair from this breeding by Vin Russo.
Here are the Rio Bravo silver and black adults:
