Omaha should still have some, right?
There is some doubt about whether the species is still in the collection. The aquarium keeps changing its answer.
Cincinnati Zoo: aardwolf and Gray's crowned guenon?
Correct on both counts. They also keep the only on-exhibit banded palm civet.
Gladys Porter has had some rare hoofstock in the past, I don't know if any remain.
Harnessed bushbuck. Gladys Porter also keeps the only long-nosed potoroos and only Guatemalan mantled howler in the country.
