Leviathans

Endemic species coexist with invasives in the highly modified ecology of Lake Ohakuri on the Waikato River. Shortfin eels writhe around the camera, while introduced rudd—the ‘possums of the waterways’—circle at a safe distance.

Produced by New Zealand Geographic

Rudd were deliberately introduced to New Zealand and distributed widely in the North Island, Nelson and Christchurch. Oxygen weed, Glyceria and Mexican daisy are also invasive species, forming ‘meadows’ that choke our native aquatic weeds.
