Rarities by Zoo

Also let me learn you guys some things about marine mammals here.

There are four Long Beaked Common Dolphin x Bottlenose Dolphin hybrids. A 50/50 female named Bullet lives at Seaworld San Diego. She is a partial second generation captive bred animal. Her father was a rescued common and her mother is a captive bred atlantic bottlenose. There is a male named CJ living at the Institute for Marine Mammal Studies in Mississippi. He is also a 50/50, his father being the same rescued common and his mother a wild caught atlantic bottlenose. CJ has produced two calves, a female named Aries and a male named Titan, both live at Discovery Cove in Orlando. Aries is 25% common, 50% atlantic bottlenose and 25% pacific bottlenose. Titan is 25% common and 75% atlantic bottlenose.

As for seals, there are a handful of ringed seals between the Alaska Sealife Center, Seaworld San Diego, and some research facilities. At San Diego their ringed seals are housed off display in the wild arctic complex. San Diego also has a harp seal. Both the harp and the ringed are occassionally placed on display, but it is rare.

The Harp Seal named Wiley currently lives at Seaworld Orlando, and has been there for quite some time. He is a reasonable age (if I can recall correctly he was rescued in the early 2000's) and has only been on display 3-4 times in the past 10 years. The Belugas are scared of him and he is somewhat shy with the public, hence him staying off display. I managed to call in a favor or two and had him placed on display for me during a recently trip to Orlando, and he is a rather small and plump fellow.
 
All dead.

Also kept at Philadelphia.

Also kept at Bronx.

Dead.

Both maintained by Emerald Forest Bird Gardens.

Held by Honolulu and one other zoo.

Held by Lubee Bat Conservancy.



All long gone.

There are multiple other holders of this species in US collections.

And as far as I know, all the Maxwell's duiker at the zoo have died out.
Thanks for the updates!

Didn't realize so many of the animals were dead.
 
Mmm also I forgot to add, there are no black sea bottlenose (T.t.ponticus) in the United States. There are 5 females at Marineland of Canada, and that's it. All the bottlenose in the states are Atlantics, along with a small number of aging pacifics and a smattering of hybrids (T.t.truncatus x T.t.gilli)
 
Thank you for the much more intensive lists than I could have ever compiled. :)
 
Sacramento Zoo: Only zoo to house giant garter snake (Thamnophis gigas)
Oregon Zoo: Only place outside Borneo to house a Borneo pygmy elephant (Elephas maximus borneensis)
Zoo Atlanta: Only U.S. zoo with raccoon dogs (Nyctereutes procyonoides)
SeaWorld San Diego's Freshwater Aquarium: Only place where you can see golden trout (Oncorhynchus mykiss aguabonita), the California state fish, in captivity
Dallas Zoo: Only U.S. zoo with perentie monitor (Varanus giganteus)
San Diego and Bronx Zoos: Only zoos in the U.S. to house geladas (Theropithecus gelada)
Please correct me if I'm wrong

Nope to these three. Chendra is the only Bornean in North America, yes, but there are also two pure cows in Europe and a number scattered throughout some closer closer to range countries, including several in china.

There is at least one other facility in the US with perentie on display (can't recall name right now)

Gelada are technically correct, however a zoo in Quebec in Canada houses a group as well.

Raccoon Dogs: Doesn't Oklahoma City have them?

Golden Trout: Common in captivity (just go to a Cabella's).
 
Okay well looks like I need to do a tad bit more research next time (I did this list solely from memory). I apologize for all the incorrect information

Just to post some more accurate information, apologies for bump:

SeaWorld San Diego houses, in addition to their more common seals, one ringed seal. They don’t have a harp seal. The ringed seal is most commonly displayed with the beluga whales, where it’ll be the only seal on exhibit.

SeaWorld Orlando houses one harp seal, and no ringed that I know of. Within the past two or so years, the harp seal, Wiley, has gone on exhibit in Wild Arctic. He shares an exhibit with two harbor seals and two beluga whales. They all have access to off-exhibit space, so it’s not uncommon to not see either the seals or the belugas.
 
Capron Park Zoo-
Brush-tailed Bettong
Visayan Warty Pig (if still considered rare)

Roger Williams Park Zoo-
Asiatic Black Bear
Komodo Dragon
Giant River Otter

Buttonwood Park Zoo-
Peruvian Pigeon
 
I wouldn't say any of those animals except maybe the Brush-Tailed Bettong are rare in USA zoos...
