The numbers are knowable
We can count what remains: two northern white rhinos, ten vaquitas, forty-two Hainan gibbons. Each profile on this site carries the best available estimate — because a number you can hold is harder to look away from.
A living register of the world's rarest animals
From a porpoise down to their final ten, to a parrot that forgot their own song — these are the animals closest to the edge, the numbers that remain, and the people refusing to let them go.
Why it matters
We can count what remains: two northern white rhinos, ten vaquitas, forty-two Hainan gibbons. Each profile on this site carries the best available estimate — because a number you can hold is harder to look away from.
Snares, gillnets, a painkiller given to cattle, a dam across a spawning river. Almost every decline traced here has a human cause, which means it also has a human solution.
The kākāpō, the condor, the black-footed ferret and the mountain gorilla were all written off. All are climbing back. The organisations behind each species page are proof that the last chapter isn't written.
