Rare and rare in captivity can be two completely different things. It also depends on the definition of boa. Rare can be a pretty subjective word.

The rarest boa in the world is Corallus cropanii. Almost mythical.

Round Island boas. There are two types of Round Island boa. Casarea dussumieri has only been produced in captivity a few times in 30 years at Durrell institute. The burrowing species Bolyeria multocarinata is probably extinct. These animals are rare because of the usual reasons , small range , habitat loss.

Often species considered rare by collectors are really pretty common. There are many types of boas that are only rare in captivity because of the political red tape involved with getting them . Clouded boas are a good example they come from a small island but their VERY common. When they had the chance collectors didn't want them . A lot of island stuff is like that. Locally common but because of whatever it becomes more trouble then it's worth to deal with So........

Trachyboas are scarce in captivity. For couple reasons. I think it's mostly because the country's of origin don't do much in live trade. I always like them but could never get two at one time. They play dead. Keeled scales Eat frogs , gold fish .

Exiliboa placata, The Oaxaca dwarf boa has a very small distribution range . I don't know if there's any in captivity. I've never seen a live one.

I'm sure theres some others that might or not be rare that I'm forgetting .
