Good grief, so now the Mendoza Serepentarium is also called Centro Anaconda. Well, some of the species you photographed are different from the ones i saw about a year ago so i suppose that there is some rotation going on. Nice picture.
The green anacondas have been split into several species. I think this is just me being silly again though. On a second look it just seems like a giant yellow anaconda.
Carlos, on the sign at the entrance and on the ticket it says 'Serpentario' and then 'Centro Anaconda' on the second line, so I'm not sure whether this is something new but it's no major rebranding.
Apparently only a tiny fraction of the collection is on display at any given time; there's a lot of rotation here.
