Xerces Blue

I always thought there were more. When entomologist W. Harry Lange was collecting insects on March 23, 1941 at the former military base Presidio in San Francisco, he unknowingly caught the Xerces blue that is now regarded as the last of its kind. Lange later commented on this and said:

Honshū Wolf

Island dwarfism led to the smallest subspecies of the wolf The extinct Honshū wolf, which was only found on the Japanese islands of Honshū, Shikoku, and Kyūshū, is considered the smallest subspecies of the wolf. Its body length was about 90 centimeters, and its shoulder height was 56 centimeters. The

White-chested white-eye

Extinct in recent times The White-chested white-eye was native only to a forest area of five square kilometers at Mount Pitt on Norfolk Island. Norfolk Island lies east of Australia and north of New Zealand. Experts assume the bird species went extinct in recent times. The last confirmed sighting of

Miller Moth

With the Miller moth, the Laysan Millerbird also went extinct The Miller moth, a nocturnal species also known as Miller or Laysan noctuid moth, was the main food source of the Laysan millerbird. When the moth went extinct, the bird disappeared as well. The Miller moth occurred exclusively on Laysan,

Pig-footed Bandicoot

Forefeet resembled those of even-toed ungulates It was above all the feet that distinguished pig-footed bandicoots from other bandicoot species in the order of bandicoots, or peramelemorphs (Peramelemorphia). The pig-footed bandicoot, from the genus of pig-footed bandicoots, owed its name to the two toes with hoof-like claws on its forefeet,

Megascolides australis gehört neben Rhinodrilus fafner (Brasilianischer Riesenregenwurm) zu den größten Würmern

Alongside Megascolides australis (image), Rhinodrilus fafner is among the longest earthworms. The drawing by Arthur Bartholomew comes from Frederick McCoy's work Natural History of Victoria (1885). Image: Arthur Bartholomew (1833–1903), Public domain, via Wikimedia Commons

Giant Brazilian Earthworm

More than two meters long On May 5, 1912, an extraordinary animal was discovered near the city of Belo Horizonte in Brazil: an earthworm more than two meters long. The species later described as Rhinodrilus fafner—also known as the giant Brazilian earthworm or Minhocuçu—reached a length of 210 centimeters, a

According to ornithologists Olson and Jouventin, the extinct Amsterdam duck was similar to the still extant, likewise flightless Auckland teal (Anas aucklandica; see image).

Amsterdam duck

Barely larger than a thrush Both Amsterdam Island and Saint Paul are more than 3,000 kilometers away from continents. Nevertheless—or perhaps precisely because of this—the two islands were frequently visited by early seafarers and the animals that traveled with them, so that all endemic birds there had already been wiped

The day-flying Levuana moth had a wingspan of 16 millimeters. Its head and thorax were steel-blue, while abdomen and legs were ochre-colored. (© Rosa Henderson, Landcare Research, CC BY 3.0 AU, via Wikimedia Commons)

Levuana Moth

A plague for the coconut industry Beginning around the 1870s, swarms of moths started destroying coconut plantations. In this way, the Levuana moth became a serious pest of coconut plants on Viti Levu, the main island of the Fiji group in the South Pacific. At first, the Levuana or coconut

Caribbean Monk Seal

Sharks and humans were the only enemies of the Caribbean monk seal The Italian navigator Christopher Columbus discovered the Caribbean monk seal—the first mammal of the New World—in 1494 during his second voyage to the Americas, on the coast of Santo Domingo, the capital of the Dominican Republic. He called

Passenger pigeon mite

Species extinctions trigger chain reactions When animal or plant species go extinct, a chain reaction is set in motion. Often, at least one other organism dies out along with it. Thus, with the passenger pigeon, the passenger pigeon mite also went extinct in 1914. In a study published in 2004,
