Smallest vertebrateIn 2006, the discovery of the world's smallest vertebrate - the Paedocypris progenetica fish - was published in the Proceedings of the Royal Society of London, Series B. A tiny member of the carp family, the transparent fish was discovered in the highly acidic peat swamps of the Indonesian island of Sumatra. Mature females are only 7.9mm (3/10 in) in length; the males measure up to 8.6mm. The dark tea-coloured swamp waters in which they live have a pH of 3, which is 100 times more acidic than rainwater. |
