~You can see the heartwarming scenes of child-rearing~
On Tuesday, September 16th and Wednesday, September 24th, 2025, two baby king King penguin were born in the "Antarctica" tank .
Both chicks have been raised by their parents under their stomachs since birth, so it has been difficult to see them, but we are pleased to announce that the first baby has started to occasionally pop its head out from under its parents' feet, and there are now more opportunities to see them raising their young, such as being fed by mouth.
Both babies are growing well, and aquarium keeper weigh them every morning to monitor their growth.

These babies were hatched in the tank after the Great Barrier Reef tank was renovated, with the eggs laid by the parent fish being collected by the aquarium keeper.
