The rhythmic bubbling proved curious and the red flashes which accompanied the bubbling also piqued my interest. Could this be some sort of strange hitherto unknown creature in little Singapore. It was not to be but none other than a school of young snakeheads accompanied by their mama who was keeping a close watch on her brood.
A hapless terrapin happenned to float by too close to the group and this deserved a nip from the mama snakehead so much so that the turtle splashed quite a bit or water in shock or maybe in pain... probably in pain for snakeheads have a fierce set of teeth lining their jaws.
From the colouration of the mama fish, it appears to be a Giant Snakehead and it was estimated to be about 75 cm long.
