Amphorotia hispida

Amphorotia hispida is a freshwater diatom endemic to Lake Baikal in Russia.

Lake Baikal is the world's largest and oldest lake. The lake holds nearly 20 per cent of the world's unfrozen surface fresh water and has many endemic species - organisms not found anywhere else. A fact explained by the the age of the lake, at 20 to 30 million years old plants and animals have had plenty of time to evolve into new species.

Amphorotia hispida was only recently discovered and described by Museum scientists Dr David Williams and Dr Geraldine Reid. The scientists also discovered a new genus Amphorotia while studying diatom diversity in Lake Baikal.

Species detail

Amphorotia hispida belongs to a genus, Amphorotia itself only recently discovered and described, which has an unusual distribution, many of its species in the Pacific, some extending as far south as the Mekon delta and, possibly, into marine waters.

Quote from author

'This remarkable new find is really only the tip of the iceberg,' said Williams. 'The diatom diversity in Lake Baikal, especially in its deeper waters, is almost entirely unknown and unstudied.'
