A tiny species of fish can claim some of the most unenviable of all records.
The so-called Devils hole pupfish survives within one of the driest places in the world, in the heart of the Mojave desert in the US.
Each fish is less than one inch-long (2.5cm), and perhaps fewer than 50 individuals survive.
At one end of this pool is a small limestone shelf, measuring just 3 metres by 6 metres. This shelf is the fish’s only known feeding and spawning ground.
As a result, the pupfish has the smallest geographic range of any vertebrate species.
