What happens when we discover a new species of animal and then never see it again? This is part 2 of my series on species that have only been seen once before they were lost.
In this video, we'll look at:
1. Delcourt's Giant Gecko
2. Nechisar Nightjar
3. Lucihormetica luckae
4. Negros Fruit Dove
5. Forpus flavicollis

[@tomeeshahaller4226]

It's a shame the Gigarcanum seemingly went extinct. A gecko that big would've been awesome to see alive.

[@samoak123]

would be an amazing pet!

Same thing with the cockroach too, as someone with Madagascar Hissers I can see them being a great animal to keep/see

I'm so fascinated by these bc it's more than a cryptid. These animals were seen, and actual evidence of them exist. Never to be seen since. But they may still be out their waiting for discovery. Each animal has such a unique story.

[@callenbyrne1310]

Yes I agree! It hits that same mystery itch without the frustration of people just blatantly ignoring science as we know it. Unless it's mountain monsters. Those boys must never stop.

[@d.i.m.eproductions6925]

Many cryptid animals became apart of the animal kingdom eventually lmao

[@Moonorchidwolf]

That's what cryptozoology is. It's the study of animals that may have escaped their supposed extinction or animals that have been rumored but never officially discovered. Because of it's portrayal in media everyone thinks it's just about mythological/paranormal creatures. I guess bigfoot is more exciting than some random lizard that we haven't seen in a long time.

Technically, the term "cryptid" encompasses known animals thought to be extinct which are still being sighted, and plausible animals whose existence hasn't been fully proven, as well as more conventional spooky stuff. I remember a time when giant squid were cryptids, and it was actually a cryptid-hunting show (Monster Quest, I think) that got some of the first footage of a live one, and the first ever footage of one not at the surface. Stuff like eastern cougars and thylacines are also cryptids.

[@Tactical_Turtwig]

Please make this an ongoing series! I love this more than even the extinction videos because there could be some hope it's not gone or the anguish of knowing we didn't appreciate them when we encountered these rare animals!

[@animula6908]

I often hear of “extinct” species being found alive. I never abandon hope because it does happen. No one has really searched the entirety of the world for anything.

[@thatonepossum5766]

We used to think crested geckos (another New Caledonian gecko) were extinct, and now they're like the third most popular pet lizard. So maybe one day we'll find the Gigarcanum again. I'd like to hope so, anyways.

[@incineroar9933]

The pink land iguana looks like it could just be a colour morph ngl

[@randomgamerdude98]

I was thinking that

[@lstan7617]

I don’t know, I see some subtle morphological differences

[@itzmetous]

I'm actually in a Galapagos islands graduate class! While it might look like that, the pink iguana is only found in the crater of one volcano. I'm the islands there's a fair number of species that end up being isolated to a singular area which hints at it being it's own species. The research station also has the ability to DNA test the animals there and it has enough genetic differences to be classified! The other land iguanas have actual patterns on them not just a color which helps to differentiate species. The pink one is just that. Pink! And documented morphs in the Galapagos have never been quite so varied.

[@jointcerulean3350]

10 minutes ago It’s morphologically and genetically very distinctive, it has a taller and deeper snout, looks more like the skull island carnosaur from 1933 King Kong in skull shape, morphology.

[@user-kt8yp5ho2y]

For the next only ever seen once series, I want to see the Acheilognathus Hondas aka Seoho(Western lake) bitterling(서호납줄갱이). It’s a species of Rhodeus that only lives in a reservoir called 축만제 in Suwon Paldal-gu Hwaseo-dong, South Korea. It was discovered by a Japanese biologist Honda Kosuke in 1911 and later reported in the US by David Starr Jordan & Charles William Metz in 1913 in Chicago. Later it was discovered by Tamezo Mori in 1926 and a Korean Ichthyologist named 강수원 in 1945 but it has never been discovered since 1945 and it was declared extinct. And now, the only specimens of Seoho bitterling are in the archive at the Field Museum Chicago.

[@SilentRacer911]

It’s sad, so many beautiful species have probably gone extinct from collecting 1-3 individuals, we have probably taken out dozens of individual species like this

[@traceursebas]

A year ago I was in the natural history museum of Copenhagen. They had a specimen of a tiny spider that never before nor after seen again. Forgot the name sadly

[@noneed4sleep64]

Pardosa danica? Someone mentioned a spider like that on the first video

[@DevilsAvocado69]

​@@noneed4sleep64The taxonomy of spiders changes regularly unfortunately, it's an attempt to keep things organised. Unfortunately it does further confuse research because you go 5 years back and the taxonomy is different from now, go 5 years back again and it's different again, so on so forth. Making research incredibly tedious and often difficult, tarantulas are the most obvious example of this. They change more that anything else I have seen in science..

[@SoapConsumption]

just today I was trying to write down all the species of rats and I noticed that a lot of them only had one or two specimens and then were never seen or observed again. Ethiopian amphibious rat, Sunburned Rat, Aceh Rat, etc. But on the bright side, The Vangunu giant rat, a rat that was discovered in 2015 and only had one specimen just got caught on camera. It's really sad that animals (especially in more rural parts of the world) go extinct because of habitat loss and because nobody cares to protect/look for them.

@kenneth9874 Nobody finds conversions difficult, "numbnuts". Again, it's about the metric system being objectively superior and more useful in the modern world. The aviation industry uses both standard international ('metric') units and US customary units, as well as nautical miles. There is no real 'reason' for this other than the fact that aviation was largely pioneered in the US.

However one mystery bird known from only one specimen is a shorebird Tringa Cooperi, at the Smithsonian. It had been collected in Hempstead, Long Island sometime in the late 1800’s

Very interesting video, my compliments! I noticed a thing, that should be corrected (I don't want to criticize, it's just a rule of nomenclature): the name of the genus is right to have the uppercase first letter, while the name of the species should have it in lowercase. Anyway, nice topic, keep on with this content! For a future video there is a "legendary" beetle known of only three specimens collected in Italy: Crowsoniella relicta. It was described in a new family and it is the only member of an ancient group of insects in Europe: Archostemata.

@@all.about.nature1987 Pioneer's lizard (Liolaemus exploratorum) (Santa Cruz, Argentina) 1896 only known from i think 2 museum specimens. It was near impossible to find images of them but I found one in an article. Oligosoma infrapunctatum Enigma Speckled Skink (Southern South Island) only a single specimen ever found but has been missing past 130 years. Colias ponteni "Wallengren" - EX 1768 A butterfly that had its location missing for centuries with Hawaii or Tierre de fuego (patagonia) being in the records but the current agreement is Tierra de fuego. Macquarie Island Parakeet (Macquarie Island) Ex - 1891 a antarctic parrot that there is only I think 3 museum specimens of and a single wing specimen. By the 1900s they were killed off. Its likely they fed off of dead seabirds similar to other kakariki parrots in subantarctic islands. This species is definitely extinct but reintroduction plans of a similar species are underway. Hall’s Thotmus Weevil (Thotmus halli) (Pitt Island) EX - 1911 Only known from a handful of museum specimens collected from New zealand and is considered extinct. Long Eared Kit Fox (Vulpes Macrotis macrotis) AKA southern california kit fox is a obscure subspecies of kit fox that was found in coastal southern californka and Northern Baja. A few museum specimens exist but the species went extinct in 1902. However it may be synonymous with the desert kit fox.

[@RealRedKoopa]

Giant Canterbury Weta (Deinacrida sp.) (Canterbury region South Island) is only known from a single subadult female specimen and individuals haven't been seen since. Its impossible to tell if it is a distinct species since the "holotype" found wasn't a adult and cant be properly determined.
