Dive duration in the Gharial
Crocodiles are known for their ability to stay underwater for a long time, sometimes over an hour. Our underwater exhibit, one of its kind in Asia, allows for viewing a gharial from an entirely differ-ent perspective. Being piscivores (fish-eaters), the turtles in the enclosure are not at risk, as the male in this enclosure, gets fed Tilapia (an invasive fish from Africa) several times a month. The gharial is among the largest crocodile of the 23 crocodilian species, reaching a remarkable length of 5m!
