Species that went extinct in 2020

We can all name our favorite endangered species—fan favorites tend to be the big, charismatic mammals like orangutans and tigers that captivate us at zoos. Some of us can even rattle off the more famous species that went extinct in recent centuries, like the passenger pigeon, whose last individual (a bird named Martha) died in captivity in 1914, or the dodo bird, already extinct by 1681. But the modern era has brought with it extinction on a new scale: We’re in the midst of the sixth mass extinction ever experienced by our planet, and humans are to blame.

All this extinction talk begs the question: Which species have gone extinct most recently? To find out, Stacker used a December 2020 press release from the International Union for Conservation of Nature, reporting from The Revelator’s John R. Platt, and other scientific sources to compile a list of 15 plants and animals that were declared extinct or extinct in the wild in 2020.

On the list you’ll find frogs and salamanders, birds and trees, and more. Some species on our list are down to the last of their kind, like rare plants now found only in botanical gardens. Others haven’t been spotted for decades, and are at long last being scratched off the list of the living. Why the lag? Conservationists want to be absolutely sure that a species is extinct before calling off the search, since the list also serves as a signal that conservation efforts can cease. It’s an especially tricky call to make, since some hard-to-find species have been known to turn up after years and years of hiding (like the Cebu flowerpecker, a bird spotted in 1992 after an 86-year drought of sightings). Biologists don’t want to declare a species extinct too early, but leaving an extinct species on the endangered list can waste precious conservation resources. In the end, it’s a judgement call made by the experts that know the species best.

Without further ado, here are 15 plants and animals we lost for good in 2020.

Splendid poison frog

- Scientific name: Oophaga speciosa

Central American frogs have had a terrible time for the past few decades, thanks to a fungal disease, chytridiomycosis, that’s been ravaging amphibian populations across the tropics. The splendid poison frog was no exception. Endemic to the forests of Panama, it was last spotted in the wild in 1992.

Jalpa false brook salamander

- Scientific name: Pseudoeurycea exspectata

This salamander was last seen in 1976, although it was once a common sight in its home forest in the Jalapa region of Guatemala (that's not a typo; it's the Jalpa from Jalapa). Since then, habitat destruction from farming, logging, and grazing left it without a home.

Simeulue Hill myna

- Scientific name: Gracula religiosa miotera

Researchers reported in 2020 that this tropical bird went extinct in the wild in the past two or three years. This myna was only recently established as a distinct species from its close relatives in Southeast Asia after researchers conducted genomic analyses.

Lost shark

- Scientific name: Carcharhinus obsoletus

The lost shark has only been observed three times in the South China Sea, most recently in 1934. But the specimens weren’t identified as a new species until 2019—long after the shark presumably went extinct. The South China Sea is one of the most heavily fished areas in the world, so it’s unlikely any individuals remain.

Smooth handfish

- Scientific name: Sympterichthys unipennis

Perhaps the strangest-looking species on this list, this Australian ocean-dwelling fish is named for the handlike fins it uses to walk along the seafloor. Although the reason for the demise of this species is unknown since it hasn’t been spotted in 200 years, other handfish are susceptible to overfishing, habitat disturbances, and predation by invasive species like the northern Pacific seastar.

Lake Lanao freshwater fish

- Scientific name: Barbodes spp.

Fifteen fish species in the genus Barbodes were declared extinct in 2020, all of them endemic to the Philippines' Lake Lanao. One of the oldest lakes in the world, Lake Lanao has been in trouble since the predatory tank goby, Glossogobius giuris, was accidentally introduced in the early 1960s.

Chiriqui harlequin frog

- Scientific name: Atelopus chiriquiensis

Another amphibious victim of the chytrid fungus, this frog was actually a toad. Despite intensive search efforts, it hasn’t been observed in its native habitat, the rainforests of Costa Rica and Panama, since 1996.

Spined dwarf mantis

- Scientific name: Ameles fasciipennis

The only insect on our list, this praying mantis used to live in shrublands in central Italy. It was only recorded once in 1871, before its habitat was thoroughly cultivated.

Bonin pipistrelle bat

- Scientific name: Pipistrellus sturdeei

Another species only recorded once, the Bonin pipistrelle is a Japanese bat observed for the first and last time in 1915. Its former home, the Bonin, or Ogasawara, Islands are a biodiversity hotspot and a UNESCO World Heritage Site.

Lord Howe long-eared bat

- Scientific name: Nyctophilus howensis

Researchers found a single skull belonging to this bat in 1972 but never found any more specimens, so reasons for its decline are unknown. Its native habitat, Lord Howe Island, is off the coast of New South Wales, Australia.

Wolseley conebush

- Scientific name: Leucadendron spirale

This South African shrub was last seen in 1933 and finally taken off the endangered species list last year. Though the reasons for its decline aren't certain, much of its habitat has been destroyed, and what's left has been overrun by invasive species.

Agave lurida

- Scientific name: Agave lurida

This Mexican agave, a close relative of the plant that gives us tequila, was last spotted in the wild in 2001. Only a few individual specimens were ever identified, and the plant's tiny range in the Oaxacan shrublands has been heavily grazed, likely leading to its demise.

Alphonsea hortensis

- Scientific name: Alphonsea hortensis

The last specimens of this Sri Lanken tree live in the Peradeniya Royal Botanic Garden. It hasn’t been found in the wild since 1969, when it grew in lowland rainforests.

Golden fuchsia

- Scientific name: Deppea splendens

This tropical beauty only ever grew in one spot in Mexico, so when its home was plowed under for cultivation, it went extinct in the wild. Luckily a botanist had collected the seeds, so the species lives on in a few botanical gardens, and gardeners can even order cultivars online for their home collections.

Hawaii yellowwood

- Scientific name: Ochrosia kilaueaensis

Once endemic to the island of Hawaii, this tropical plant witnessed its rainforest habitat devastated by invasive plant and animal species since its last sighting in 1927.
