Giant Croc Swims like a Dolphin

North Queensland fisherman captured incredible images of an enormous saltwater crocodile swimming near a boat like a dolphin.


Alec Dunn filmed the crocodile porpoising nearby his boat in the Bloomfield River near Cairns.


Dunn said Tommy was swimming underneath his boat before he emerged and followed him into shallow waters. He came up with this growl and locked eyes with me. I was only in a 3.5m tinny and he cruised right next to me. It was interesting,' he claimed. 'He was gaffing it for that deep water. He was sizing me up and I thought he was going to go for the tinny, but lucky he didn’t,' he added.


Tommy is one of around a dozen large crocodiles in the area known to local fishermen, but it is not the largest. 

The video footage of the crocodile went viral on the Internet, prompting many observers to wonder why it was traversing like a dolphin.


Dunn believes he was simply coming up to breathe after bounding off the bottom of the river. 


David White, a guide at the Daintree River, said Tommy's behavior was unusual and extremely dangerous. He said, 'That's an angry dive down, not one we usually see when they are just hiding.


Tommy's dipping and diving did not worry Australia Reptile Park's Reptiles supervisor, Daniel Rumsey. “Crocodiles don’t usually breach when they’re moving fast like in the video,” he explained.


They swim beneath the surface when in a predatory mode, barely making a ripple. They come up for air when they do come to the surface. Crocs breaking the water's surface could just be due to the speed at which they are moving. It could even be moving over a log underwater,” he added.


Adult crocodiles can reach speeds of up to 20 km/h but cannot swim at a high speed for long periods of time as they are ambush predators. Tommy then slowed down after Alec stopped recording.
