Hope for the Yangtze: study shows how a fishing ban is reviving the river

The Yangtze River is Asia’s longest river at over 6,300 kilometers and the third-longest river in the world. For millennia it was among the world’s most species-rich freshwater ecosystems. It supplied people, animals, and entire cultures with water, food, and habitat—and formed the ecological backbone of large parts of China.

Rediscoveries in 2025: Animal species believed to be lost and extinct

Rediscoveries in 2025: These animal species were considered lost or extinct

Species do not simply disappear just because no one has seen them for a long time. And they are just as little “saved” just because they suddenly reappear. Rediscoveries mark a narrow line between hope and uncertainty: they show that life can endure – often, however, only barely. In 2025,

Chinese river dolphin: Is the baiji still alive?

The last confirmed sighting of the baiji, also known as the Chinese river dolphin, is now more than 20 years ago. The IUCN therefore classifies the species as “Critically Endangered (Possibly Extinct)”. Scientifically, its continued existence is considered extremely unlikely, but occasional sighting reports and video recordings at least leave

The kouprey is among the most enigmatic wild cattle in the world. First described scientifically in 1937, it was already extremely rare at that time. Characteristic features include the frayed horn tips of mature bulls and the pronounced dewlap. Today, according to the IUCN, the kouprey is probably extinct. (© Illustration aus Coolidge, H. J.

The Kouprey: A Zoological Mystery

The kouprey is considered one of the most mysterious wild cattle in the world. First described by Western scientists only in 1937, this shy animal from the tropical forests of the tri-border region of Vietnam, Laos, and Cambodia remained scarcely studied for decades. Many zoologists saw the kouprey as a

Last Hope for Rescue: The Search for the Yangtze Giant Softshell Turtle

It is one of the rarest turtle species in the world — it may even be the rarest of all: the Yangtze giant softshell turtle (Rafetus swinhoei). The species is critically endangered and may already have disappeared from the wild. At present, only two male individuals are known worldwide. Yet

Schomburgk’s deer — Could it still exist?

The riddle of Schomburgk’s deer “No one seems ever to have seen this animal; all that we think we know about it is the existence of its antlers”, noted Phya Jolamark Bhicharana wrote in 1932 about Schomburgk’s deer. The American biologist Francis Harper also wrote in 1945 that this deer—which

The Yemen gazelle, which was described solely on the basis of skins, was probably similar in size to or larger than the mountain gazelle (Gazella gazella), which reaches a body length of up to 1.2 metres. (© The Great Mule of Eupatoria, CC BY-SA 4.0, via Wikimedia Commons)

Yemen Gazelle

Named after Bilqis, the Queen of Sheba The scientific species name of the Yemen gazelle, bilkis, are derived from Bilqis, the Queen of Sheba, a legendary figure in Islamic, Jewish, and Christian traditions. Her kingdom, renowned for its wealth and cultural flourishing, lay in southern Arabia, in what is now

New Study: Dwarf Hippopotamuses and Elephants in Cyprus Driven to Extinction by a Few Thousand People

New research reveals that dwarf elephants (Palaeoloxodon cypriotes) and dwarf hippopotamuses (Phanourios minor) on the Mediterranean island of Cyprus were driven to extinction after the arrival of Paleolithic humans around 14,000 years ago. A small population of possibly just 3,000 people was enough to wipe out these animals within a

Russia: Believed-to-be-extinct Abrau Sprat Rediscovered

In October 2019, researchers collected nine small fish during an expedition from Lake Abrau in the Krasnodar region of western Russia. Recent DNA analyses have confirmed that the captured fish are indeed the endemic Abrau sprat (Clupeonella abrau), a species that had not been recorded since 2008. Challenges for the

Hokkaidō Wolf

Harmful animals in Hokkaido In Japanese mythology, both the extinct Honshu wolf and the Hokkaido wolf, also known as the Ezo wolf, are revered as benevolent beings. One legend, similar to the Roman myth of Romulus and Remus, recounts that a son of Fujiwara no Hidehira, a 12th-century Japanese noble
