Strange life forms have evolved in the peat swamps of Southeast Asia, harsh habitats once thought to be devoid of life.
Eleanor Adamson, fish researcher at the Natural History Museum, introduces some recent expedition finds, including the world’s smallest fish. They have evolved to survive in water that is at least 100 times more acidic than rainwater. Many are able to breathe air.
These specialised species are not found anywhere else in the world. But their unique habitats are threatened by logging, urbanisation and agriculture. Estimates suggest perhaps 60% have gone already, possibly taking many remarkable fish species with them.
