Eunectes beniensis

Eunectes beniensis is a species of boa, reaching between in length and can weigh up to . It was initially believed to be the result of hybridization between the green (Eunectes murinus) and yellow anaconda (Eunectes notaeus), but was later determined to be a distinct species. Its taxonomic status is unclear due to lack of information and the similarity in appearance to Eunectes notaeus. It is closely related to Eunectes notaeus and Eunectes deschauenseei. ==Range, habitat and behavior==

The Bolivian anaconda's habitat usually consists of wetlands and other muddy, swampy or flooded areas. It is known only from northern Bolivia. In April 2022, three researchers published data on an observation of Bolivian river dolphins playing with a large (presumably deceased) E. beniensis specimen. ==References==
