Mangroves serve as feeding and breeding grounds for many fish species including the barramundi.
Fish[edit]
Fifty-three species of freshwater fish have been recorded in Kakadu's waterways; eight of them have a restricted distribution.
In comparison, the Murrayxe2x80x93Darling river system, the most extensive in Australia, now supports only 27 native fish species.
Although introduced fish have been found in most Australian waterways, none have been recorded in the park.
The property protects an extraordinary number of plant and animal species including over one third of Australiaxe2x80x99s bird species, one quarter of Australiaxe2x80x99s land mammals and an exceptionally high number of reptile, frog and fish species.
