Only Found in Captivity - 20 species that no longer roam free

[@tankt13]

Wow, you included the Guam Kingfisher. I’m from Guam born and raised and my folks clearly remember seeing numerous kingfisher’s when they were children. The brown tree snake destroyed almost all of our birds here to include the Marianas Crow, the Marianas fruit bat and the Guam Rail. We don’t see any of these animals anymore but we still see a lot of the brown tree snake. Also rhino beetles were accidentally brought here and wrecked havoc on the island’s coconut trees and palm trees. It would be best to release the Guam Kingfisher elsewhere, even if the snakes were wiped out, the island isn’t healthy enough to support the bird 😢

In 1999 I did some prac work at Perth Zoo in the Ungulates and Carnivores section. Being the prac student among my first tasks were to grab a wheelbarrow and shovel and clean up pens. One of those pens held 4 Scimitar Horned Oryx. They are large antelopes, but their poop is like rabbits, just in quantities suitable to a large antelope. So here I was, with a wheelbarrow full of oryx pellets, wheeling it past Memphis - the zoo's famous white rhinocerous. Memphis has been well trained by his keepers and is curious and playful. This day he decided to poke his head through the bollards keeping him in his night quarters and lodged his horn under the rim of my wheelbarrow. I am considerably smaller than Memphis, but I was NOT going to let him top over all my hard, shitty work. I did manage to win that one, I'm still not sure how. The Oryx were moved to Monarto Open Plains Zoo in South Australia in 2000.

[@galebailey5583]

I don’t know if it counts, but the California condor should have received a mention. It almost went completely extinct in the late sixties and seventies, but luckily conservationists captured several birds and bred them for reintroduction to the wild. The first efforts were unsuccessful, but they didn’t give up. Today it again flies the wild skies, but numbering only about 560 individuals, it is still the most endangered bird of prey in the world.

[@jeffslote9671]

The singer Johnny Cash almost killed off the entire species

[@scarecrow9501]

Ironically in trying to save the condor they actually made a parasite go extinct since it specialized in California condors.

[@scarecrow9501]

Basically they removed all parasites off the bird to give it better chance of survival little did they know…. I believe this resulted in a whole department for endangered parasites.

[@daffers2345]

The story of the California condors is a great story of conservation and re-establishment. It's one of my favorites. I didn't know about the parasite, though. That's pretty interesting.

[@YochevedDesigns]

These captive breeding projects are often called "invisible arks". The Egyptian Tortoise is extinct in the wild, due to over collecting in the pet trade and habitat loss. There are a few Negev tortoises left, and a small population of Libyan tortoises, but they are highly protected in the wild. You can still find these tiny desert species at reptile trade shows, but they are very few and extremely expensive. I'm planning on getting my first breeding colony of Egyptian tortoises soon, and I can't wait!

[@chadgorosaurus4898]

The fact that those isopods were limited to just one absolutely tiny body of water is crazy.

[@RCSVirginia]

The information at 19:23 is quite pertinent. Throughout the American Desert Southwest, there are numerous man-made pools and stock-ponds that hold water all year round. There are, also, nearly-ephemeral streams that have basins, some of which could certainly be deepened and enlarged if needed, that retain water when the rest of the stream dries up. As so many of these are not connected to any other water system above ground, very little outside reaches them, and any animal put into them would be confined. These would be perfect for the reintroduction of endangered or extinct-in-the-wild aquatic life for which they would provide a suitable environment. In fact, there is a whole river--creek to those who live in the Eastern part of the United States--in Tucson, Arizona, called the Santa Cruz River, that is formed from the treated effluent from the city sewage plant. It both provides wildlife habitat and a source of regeneration of the underground aquifer as its flow slowly seeps through the sand downwards. Tucson Water's Santa Cruz River Heritage Project released Gila Topminnows into this river in 2020 and Longfin Dace there in 2022. As the extirpated Santa Cruz Pupfish used to live there, as well, it would seem like an ideal spot to release an endangered or extinct-in-the-wild pupfish.

The white minow, endler, crested gecko (up to 1994 in wich was rediscovered) ... All extinct in the wild, surviving in the pet industry

[@YochevedDesigns]

And the axolotl. They'll be completely extinct in the wild within 5 years or less.

[@marks_reptiles_and_inverts]

Crested geckos are not EW

[@eljanrimsa5843]

The crested gecko is the completely wrong example. It had been considered extinct for over a hundred years, but no captive population existed back then. A surviving wild population has been found in its native New Caledonia in 1994, and this wild population still exists, currently classified as vulnerable. All crested geckos in the pet trade are originally from this rediscovered population. Endlers livebearer survives in the wild in Venezuela, too. It has no IUCN status because there is no scientific consensus if it's actually a separate species or just a regional variety of the common guppy. The White Cloud Mountain minnow is actually extinct in what had been thought to be its original habitat, the White Cloud Mountain in Guangzhou, China. But a population has been found on Hainan Island, and more research is needed to figure out if it is native there, and therefore it is classified as Data Deficient.

[@iluvmybleach]

My local zoo has extensive breeding programs for the wyoming toads and trumpeter swans where we release some of the offspring every year. We also breed the golden frogs and oryx's from this video but mainly for backstock for overall genetic diversity. Very proud of the hard work these conservationist are doing.

[@daffers2345]

It hurts when I hear people say that zoos are just "animal jails" and that they're bad because "animals should be free." A good accredited zoo will give the creatures as good a life as possible, educate visitors about their needs and environments (which is so important), and may even include breeding programs like the ones you mentioned, in order to keep the populations going. Should animals be free? Duh. But is it best for them and their own safety? Not usually, especially the endangered ones that are sought for things like traditional medicines, or if the animals were abused or kept as pets (they are often used as "ambassador" animals). We made this mess, but we're trying to fix it, and I love that zoos and breeding programs exist to help.

There is another category that one could make if you consider there are animals are considered in the wild that only are in reservations or under such human protection as to be captive. The Devil's Pupfish lives on a shelf with in the Devil's Hole with Ash Meadows National Wildlife Refuge in Nevada. It's technically part of Death Valley National Park. This little pupfish can't be cross breed with it's nearest relative the Death Valley Pupfish because it's makeup is is essentially all recessive. Technically within their wild home, they are so monitors and protected, it's practically a captive environment.

I can mention some more fish: 1. Lake Victoria cichlids. There are many species here, that are basically extinct in the wild. What started this was the introduction of Nile perch in Lake Victoria. It is a complete disaster both for the cichlids and the people that live around the lake. Some species of cichlids still survive in the aquarium hobby, but a complete overview is hard to get. As long as there are Nile perch in the lake, these cichliids will never return. 2. Nothobranchius species. Small, egglaying fish from Africa. Some of these species only inhabited one pool of water, and if that habitat is destroyed, the fish are gone. Because of their color, some aquarists still keep some species alive. These fish are famous for a couple of reasons: their color, how they breed and how fast they grow. They lay their eggs in the mud and some species eggs actually need a dry period to develop. Aquarists use this to breed them in peat filled jars, then take out the egg filled peat and dries it for a while. This means you can actually send these fish (eggs) by post - as long as it does not get too cold. If I remember correctly, these fish also hold the record of reaching fertile age/size for any vertebrate. From hatching to mating, they only need three weeks.

I'm not sure if it's currently happening but in february 2024 the 'Alalā Project was planning to release some birds on Maui Island in the spring, as there are no hawaiian hawks there.

Literally all of the new caledonian geckos, alligator lizards & many more beg to differ. Private collections are one of the best way to ensure a good animal stock. Even illegal exports can help with species preservation (as seen with many Australian animals like the Rough scaled python, where a few specimens were smuggled into Europe, which were used to create a breeding stock for zoos/private collections worldwide). In fact, the private keeping sector is one of the least concerns animals have.@@YochevedDesigns

Realized I have actually seen the scimitar oryx before, just not alive, and only part of it. The college I went to was old, and one of the classrooms in the science building had a bunch of stuffed African ungulate heads mounted on the walls. Like, every wall of the room was just covered in animal heads. I'm not exactly sure why we had a room of African ungulate heads, but we did, though my best guess was that it was a biology classroom at some point. I had a physics class in there, and I always felt like the heads were staring at me. But one of the heads was a scimitar oryx.

[@wolfbyte2468]

The Eastern Elk has been shown through genetic analysis to have not been a distinct subspecies of elk. There were only ever 3 subspecies of elk in the Americas in recent times: The Roosevelt Elk, the Rocky Mountain Elk, and the Tule Elk. All other subspecies have been subsumed into either the Roosevelt or Rocky Mountain Elk, with the Eastern Elk turning out to just be the easternmost population of Rocky Mountain Elk. So that is neither extinct nor extant, since it never technically existed. Studies on Brown Bears in the Americas are more unclear, but there's a decent chance that the Californian and Mexican Grizzly Bears were not distinct subspecies. But more research on that needs to be done. Hope this helps!

Interestingly, quite a few popular and easily attainable houseplants are extinct in the wild. I have one and didn’t even realize it. _Philodendron hastatum_ is apparently non-existent in the wild in Brazil nowadays. Yet it’s pretty commonly available for sale as the teal-colored cultivar, ‘Silver Sword’. I literally bought one for $15, plus two baby plants for $4.99 each. Have to take extra care!! Northern Africa has quite a few extirpated or absent animals. Much like the scimitar-horned oryx, there’s the dama or addra gazelle, which has experienced a similar fate. However, the gazelles haven’t done quite as well with being reintroduced as the oryx have, and even the oryx are monitored. I think feral dogs killed them or something. The rarest subspecies of dama gazelle is the Mhorr or Mhorr’s gazelle, which is extinct in the wild and only exists in some zoos worldwide. The Mhorr subspecies has much more maroon, brick-red coloring over its body, as opposed to the mostly-white damas with their orange necks. Also, isn’t the addax extinct in the wild in Africa? Common in captivity, but hasn’t succeeded with reintroductions.
