Caulker Cay boas are very similar to Hog Islands (Hog - not Hogg). Just like all of the insular localities, they tend to be smaller than the average mainland BCIs. Care and husbandry are the same as for any BCI. Caulkers are a little harder to find in the hobby, but not as rare as some insular varieties. They are one of the smallest locality boas with most not getting larger than 4 ft.

All BCI are hardier and less sensitive than BCC.

I am not familiar with Michael Beach, so I can't comment there, but check to see if the info he is giving you jives with the link I posted above (which is Vin Russo's site - can't go wrong with Vin as he is the foremost authority on captive bred locality-specific boas in the US).
