Here are a few species I hope to see in the coming months Black Caiman Cuban Crocodile Chinese Alligator Morelet's Crocodile African Slender Snout Crocodile
Just out of interest @bongorob, whose taxonomy are you following that lists Alligatoridae as a subfamily of Crocodylidae? I've never seen that before. Here's my (relatively sparse) list: Crocodylus acutus Crocodylus intermedius Crocodylus johnsoni Crocodylus mindorensis - first seen at Chester Crocodylus moreletii- first seen at Knowsley Safari Park Crocodylus niloticus - first seen wild in South Africa Crocodylus novaeguineae Crocodylus palustris Crocodylus porosus Crocodylus rhombifer Crocodylus siamensis Crocodylus suchus Mecistops cataphractus Osteolaemus tetraspis- first seen in a private collection ---- Gavialis gangeticus Tomistoma schlegelii - first seen at Chester ---- Alligator mississippiensis - first seen at the Welsh Mountain Zoo Alligator sinensis Caiman crocodilus -first seen at Chester Caiman latirostris Caiman yacare - first seen at Blackpool Melanosuchus niger Paleosuchus palpebrosus - first seen in a private collection Paleosuchus trigonatus - first seen in a private collection
Swampy I can't remember,it's probably an old classification. Wikipedia has Alligtorinae as a subfamily, but that does not prove anything.
Ah, but that's as a subfamily of Alligatoridae, separating Alligator from Paleosuchus, Caiman & Melanosuchus, which are placed in the Caimaninae. Sorry to get all pedantic, I just thought it was an interesting alternate taxonomy
And I'm sorry to see that they seem to have settled on "West African crocodile" for that new species and not cooler names such as "sacred crocodile" or "desert crocodile."
I haven't kept a detailed list but of recent viewings, the Toledo Zoo has a seventeen foot salt water crocodile. When I lived in Chicago some years back the Lincoln Park Zoo had an Orinoco crocodile, and I don't recall seeing those elsewhere. Detroit currently has Siamese crocs and had a pair of African dwarf crocodiles, but no longer. We currently have Siamese crocs and Chinese alligators.
I hope that name eventually will be forgotten since a much larger part of its range is in forest than desert. Can anyone imagine visiting this place and being in the strange situation of having to call out: "Look, a desert crocodile!" Speaking of taxonomy: It appears the slender-snouted crocodiles in North American zoos are of the Western form (species). Does anyone know about the slender-snouted crocodiles in Europe? Would be interesting to see a Central, but for conservation it would be preferable if they all are Western, too.
It hasn't been fully confirmed as yet, but there is some suspicion that the European population partially comprises hybrid stock.

A very interesting and informative read. But why the discrepancy between ZIMS and zootierliste? do not all collections contribute to ZIMS?
Simple it costs money to join ZIMS which they have to pay each year they want to be a member of ZIMS.
A few years ago I toured Phoenix Herpetological Society in Scottsdale, Arizona (USA). They have all but two or three of the world's crocodilian species. I imagine they are second only to Saint Augstine in USA collections. I did not record which species I saw or which two or three they are missing (and their website does not include a species list).
That seems likely. In Europe Krokodille Zoo in Denmark has all the species if using traditional taxonomy (i.e., before recognition of West African croc, and splits of dwarf and slender-snouted crocs), but they typically have a few species off display so you won't see everything on a visit. Next is Krokozoo in the Czech Republic that has all but one if using traditional taxonomy. The missing at Krokozoo is Orinoco; the only Orinocos outside the Americas are at Krokodille Zoo and with the difficult situation in Venezuela (where quite a number are at breeding farms) it seems the US is now the main place for it.
I guess I'm a bit late to hop on the bandwagon, but here's my list: Crocodylus acutus - first seen at Cincinnati Zoo (2010) Crocodylus intermedius - first seen at Newport Aquarium (date unknown) Crocodylus johnsoni - First seen at San Diego Zoo (2015) Crocodylus mindorensis - First seen at Gladys Porter Zoo (2016) Crocodylus moreletii - First seen at Dallas World Aquarium (2014) Crocodylus niloticus - First seen at Disney's Animal Kingdom (date unknown) Crocodylus novaeguineae - First seen at St. Augustine (2016) Crocodylus palustris - First seen at St. Augustine (2016) Crocodylus porosus - First seen at Fort Worth Zoo (2014) Crocodylus rhombifer - First seen at Gladys Porter Zoo (2016) Crocodylus siamensis - First seen at (I forgot which zoo- either Ellen Trout or Animal World and Snake Farm) (2016) Crocodylus suchus - First (knowingly) seen at St. Augustine (2016) Mecistops cataphractus - First seen at Kansas City Zoo (date unknown) Osteolaemus tetraspis - ZFirst seen at Fort Worth Zoo (2014) ---- Gavialis gangeticus - First seen at Cleveland Metroparks Zoo (2010) Tomistoma schlegelii - First seen at Saint Louis Zoo (date unknown) ---- Alligator mississippiensis - No idea when I first saw, but have seen in many zoos as well as wild. Alligator sinensis - First seen at Saint Louis Zoo (date unknown) Caiman crocodilus - First seen at St. Augustine (2016) Caiman latirostris - First seen at St. Augustine (2016) Caiman yacare - First seen at St. Augustine (2016) Melanosuchus niger - First seen at St. Augustine (2016) Paleosuchus palpebrosus - Have seen this one all over Paleosuchus trigonatus - First seen at St. Augustine (2016) Dates are only by first memory of each species, but I have seen several before their listed dates. As for splits: have not seen Central African slender-snout, or any dwarf croc other than the one I listed.
I was wondering which I had already seen, so here we go: Crocodylus acutus Crocodylus intermedius Crocodylus johnsoni Crocodylus mindorensis - Zoo Köln Crocodylus moreletii Crocodylus niloticus - Beekse Bergen, Blijdorp, Terrazoo Rheinberg... Crocodylus novaeguineae Crocodylus palustris Crocodylus porosus Crocodylus rhombifer Crocodylus siamensis Crocodylus suchus Mecistops cataphractus - Blijdorp Osteolaemus tetraspis - Zoo Magdeburg ---- Gavialis gangeticus - Zoo Berlin Tomistoma schlegelii - Artis, Tierpark Berlin ---- Alligator mississippiensis - Terrazoo Rheinberg, Tierpark Berlin Alligator sinensis - Tierpark Berlin Caiman crocodilus - Zoo Berlin Caiman latirostris - Burgers' Zoo Caiman yacare - maybe* Melanosuchus niger Paleosuchus palpebrosus - Zie-Zoo, Breda, Ouwehands... Paleosuchus trigonatus - Rome, Tilburg * I've probably seen caimans pre 2007 at Burgers', but I don't know for sure, so that doesn't count. In conclusion, I've seen most species outside the Crocodylus genus, but I've only seen a very few species within that genus. And quite a lot actually. So it's only logical that small zoos with a small budget don't register.
I hope more zoos keep rare crocodile species. Looking at Zootierliste, there are several tens of holders of mix Nile crocodiles, spectacled caimans and American alligators. If they could be replaced with endangered forms or at least pure subspecies, zoo could contribute significantly to conservation. Indian Gharial will likely need captive insurance population forever. Its natural habitat was almost destroyed. There are few stretches of big undeveloped rivers in India left, and wild population cannot grow more than the current few 100s. I think I already written that one idea to boost captive breeding of crocodiles may be to get individuals for temporary breeding loans to existing big exhibits, and return them once they produce one or few clutches.
Here's my list; by taxonomies, and in order of frequency! However, some of the places I saw them no longer have them there; I will write said places in bold.
