Acentrogobius janthinopterus
Robust Mangrovegoby
Much of what follows is drawn from a pair of field-trip photo-essays documenting a series of collecting trips between Cairns and Weipa on Cape York, which turned up an extraordinarily rich cross-section of Australia and New Guinea’s smaller estuarine and mangrove-associated gobies.
An ambush predator photographed at the Weipa tidal flats, Acentrogobius janthinopterus shelters under rocks and in burrows waiting for prey; its prominent teeth, lining both jaws, help it grab and hold onto whatever it catches.
