Marine biology: Appeal launched to find rare Madagascan fish


A worldwide appeal has been launched to find a mate for the last remaining males of a fish on the brink of extinction. The Mangarahara cichlid, from Madagascar, is believed to have vanished from the wild as a result of the building of dams on the Mangarahara River.

Two of the last known members of the species are in London Zoo’s aquarium, but both are male, the Zoological Society of London said. A search of zoos and aquariums around the world failed to find any females.
