Guys, seriously, have you even read the OP's posts? Do you know anything about Epicates Cenchria?
This is a wild snake caught on the island of Trinidad, a fairly well-known island Northeast of Venezuela and Northwest of Guyana.
There are nine recognized subspecies of rainbow boa, what makes you all SOOOO sure that it's a BRAZILIAN rainbow boa? My guess is that it's because YOU think it's the most common, because here in the US, it is.
It doesn't take much effort to just look up species native to Trinidad. All the rainbow boas on Trinidad are currently classified as:
Epicrates cenchria maurus, or the COLOMBIAN rainbow boa, which only makes sense since their range is much more northern compared to BRBs.
