Meet eight remarkable species that once shared our planet—and trace the choices, changes, and chance events that erased them.
↓ Begin the journeyExtinction is natural over geological time. But many recent losses happened unusually fast, driven by hunting, introduced species, habitat destruction, and a changing climate. These animals are more than curiosities: they are evidence.
A cold-adapted elephant covered in long hair, with curved tusks and a shoulder hump of stored fat.
A flightless island pigeon that evolved without large predators—and had little defense when people and introduced animals arrived.
An enormous, gentle marine mammal related to dugongs. It grazed kelp forests in cold northern waters.
A powerful swimmer and flightless seabird, harvested for meat, feathers, oil, and museum specimens.
A plains zebra subspecies with stripes concentrated on its head and front half and a brown, unstriped rear.
Once among Earth’s most abundant birds, its immense flocks darkened the sky. Industrial hunting and forest loss collapsed the species.
The largest modern carnivorous marsupial, remembered for its stiff tail, striped back, and remarkably wide-opening jaws.
A giant predatory shark known mostly from fossil teeth. It hunted marine mammals across warm seas.
As human travel and technology expanded, isolated species faced threats they had never evolved to withstand.
The dodo and Steller’s sea cow disappeared within decades of sustained human contact.
Commercial demand for meat, feathers, hides, and specimens pushed the great auk and quagga beyond recovery.
The passenger pigeon vanished in 1914; the last known thylacine died in captivity in 1936.
Conservation can work, but only while breeding populations and habitats still remain.
“Extinct” is the one conservation status that cannot be reversed.
