Black Tailed Tree boas or Central American Tree boas are a small to medium, more robust and typically larger at 5.5-7ft adults than their cousin the Amazon tree boa. Less variable in color as well with olive greenish base color with dark greyish black pattern elements darkening posteriorly to a black tail in much of its range. Some of the southern specimens are reddish brown and nearly pattern less. Occurring from southwestern Costa Rica to just into north westerns South America and several islands like Trinidad and Tobago.
I work with a pair from Costa Rica lineage.
