I'm not sure why I post so many mixed species exhibit threads, but here's another. Does anyone know a mix species exhibit with the most number of species?
The world's largest mixed exhibit by species number is likely not the largest by size. I suspect the above suggestions of either an aviary or marine tank is correct for species number, though who knows which one wins the title. As far as size goes, a mixed savanna or other hoofstock enclosure is likely the largest. Maybe one of the massive elephant habitats which mix them with hoofstock/birds? ~Thylo
Also the main open ocean tanks at Sentosa SEA Aquarium and Okinawa Churaumi Aquarium might be up there.
