16 Rare Animals Rediscovered This Century
Scientists lose track of animals all the time. Sometimes it's because they live in places nobody wants to visit, like swamps or mountaintops. Other times, people just assume they're gone when nobody sees them for a while. But every now and then, these missing creatures show up again, usually when someone least expects it.
The past 25 years have brought some pretty amazing surprises in this department. Here is a list of 16 rare animals that scientists have rediscovered this century.
Fernandina Giant Tortoise
A research team found a female tortoise on Fernandina Island in 2019, which was a big deal because nobody had seen one since 1906. She was probably over 100 years old and had been living on this volcanic island the whole time. The team also found tracks and poop from other tortoises, so she definitely wasn't the last one.
Attenborough's Long-beaked Echidna
Trail cameras caught this spiky egg-laying mammal on video in Indonesia during 2023. It had been 60 years since anyone spotted one, and researchers weren't even looking for it when they found it. The echidna lives in the Cyclops Mountains, which are pretty hard to get to.
Vietnamese Silver-backed Chevrotain
This tiny deer showed up in Vietnam in 2019 after being missing since 1990. It's about the size of a rabbit and is actually the world's smallest hoofed animal. Camera traps finally got pictures of it in the forests, proving it was still around after nearly 30 years.
Terror Skink
This lizard with the scary name turned up on a small Pacific island in 2003. It has sharp, curved teeth and eats meat, which is unusual for a lizard. Nobody had seen one since the 1870s, but it had been living on remote islands where tourists never go.
De Winton's Golden Mole
Researchers in South Africa used a specially trained dog to find this mole in 2023. The blind, shiny mole lives completely underground and doesn't make tunnels like regular moles do. It had been missing since 1936, which made finding it pretty tricky.
Cuban Solenodon
Someone found this weird mammal in a Cuban park in 1974, just four years after scientists said it was extinct. It has venomous spit and a long nose that it uses to hunt lizards and frogs. Before the rediscovery, people thought it might be the rarest animal on Earth.
Pygmy Tarsier
These tiny primates with huge eyes showed up in Indonesia in 2008. They live in trees and can jump incredible distances between branches. Nobody had seen them since the early 1900s, but they were hanging out in the mountains of Sulawesi the whole time.
Wallace's Giant Bee
The world's biggest bee came back in 2019 when researchers found it on some Indonesian islands. This thing has a wingspan of about 2.5 inches, which is massive for a bee. It builds nests inside termite mounds and has been missing for 38 years.
Starry Night Harlequin Toad
This black and white spotted toad reappeared in Colombia in 2019. A fungal disease had wiped most of them out in 1991, but some survived in the mountains. Local indigenous people knew about them the whole time but didn't tell scientists until recently.
New Guinea Big-eared Bat
An Italian scientist collected the only known specimen of this bat in 1890. Nobody saw another one until 2012, when researchers found more living in Papua New Guinea's rainforests. The bat's ears are comically large compared to its body size.
Javan Elephant
These smaller elephants showed up in Borneo sometime in the early 2000s. People thought they had died out in the 1800s, but a small group had been living quietly in the jungle. They're gentler than regular elephants and not as big.
Arakan Forest Turtle
This turtle from Myanmar came back in 1994 after being gone for more than 100 years. Hunters and habitat loss had supposedly killed them all off. Turns out some were still living in protected forest areas where people couldn't get to them easily.
Large-billed Reed Warbler
This little bird had been sitting in museums for decades, but scientists kept calling it the wrong name. Someone finally figured out in 2006 that it was actually a different species that was supposed to be extinct. They found live ones in Thailand after looking in the right places.
Horned Anole
Birdwatchers in Ecuador spotted this lizard in 2005, and scientists confirmed it in 2007. It has a flexible horn on its nose that makes it look like Pinocchio. The lizard had vanished right after being discovered in 1953 and stayed hidden for over 50 years.
Lyon's Grassland Striped Skink
This Australian lizard showed up again in 2023 after disappearing for 42 years. Researchers thought it was probably extinct because its grassland habitat had been destroyed. They finally found some living in northeastern Queensland.
Black Kokanee
This freshwater salmon turned up in a Japanese lake in 2010. It used to be common in Lake Saiko but disappeared in the 1940s because of overfishing and habitat changes. Finding it again got people interested in fixing the lake's ecosystem.
