Living in fresh or brackish water, these predators (25 to 30 cm) of rivers are found in the IndoPacific sphere. A catadromous species, it is born at sea, migrates to rivers to grow before returning to the sea again to reproduce (only once in its life) and die. An eel seen in fresh water has never reproduced. Frequenting lakes, mangroves and river mouths, this bird with its white fleece, uncommon in N.-C., lives in colonies. Recognizable by its hooked black beak and its beige belly streaked with red, this raptor hovers above wetlands. This emblematic species, a vestige of the ancient fauna of Gondwana, is microendemic to the Lakes Plain. This rare fish particularly likes fresh water and rocky bottoms. Rather carnivorous, it feeds on small crustaceans and aquatic insects. It is seriously threatened with extinction due to the introduction of other fish (Black bass, Tilapia, Rainbow fish) which feed on it, chase it from its territory or enter into food competition.

Thus, several scientists, including recently a team from the IRD, the IAC and from Poland, noted that the forest had, in places, become silent. They highlighted a causal relationship between this silence and the presence of the electric ant. Indeed, this invasive species, introduced in 1960, devastates everything in its path. Many insects (worms, caterpillars, cockroaches, etc.) are disappearing, causing a change in soils and animal populations. The decline of these various insects, which are the kagubirds’ only pantry, leads the latter to flee and drastically reduces their living space. This small (2 cm) speckled shrimp, living strictly in fresh water, displays a multitude of colours (blue, yellow, black, red, white, etc.) From the order of Trichoptera, this larva adapted to life in fresh water makes a small sheath from sediment to form a roof. Endemic to temporary sinkholes, the female lays eggs when the sinkhole is wet, which only hatch after a period of drying. The new generation will only appear at the time of re-watering. *rediscovered in the South more than 130 years after its first collection in the AnseVata Marsh of Noumea (before 1883).
