Lowland longjaw galaxias (Galaxias cobitinis)

One of the rarest freshwater fish in New Zealand, known only from a few sites in Otago and the Mackenzie Basin, this small whitebait species faces multiple threats. Its rivers and tributaries are degraded by waterweeds, sedimentation, widely varying water levels and invasion by predatory trout. 

Riparian fencing and planting, and intensive interventions by the Department of Conservation is helping to halt its decline.
