DSC_5747 Eldons galaxias (Galaxias eldoni) with only 18 known populations left, Eldon’s galaxias are one of New Zealand’s rarest freshwater fish. They are found in eastern areas of Otago. They live in small tributaries of the Taieri, Waipori and Tokomairiro rivers, draining from the Lammerlaw range, downstream of Lake Mahinerangi. They make their home under banks and amongst the gravels of very small headwater streams that are typically about 200–900 m above sea level and surrounded by vegetation such as tussock, mānuka and coprosma. This very large individual is from Stony Stream, Lammerlaw Range.
