Sweatheart the croc lived in a river system in the NT and was famous for attacking running outboard motors. He was estimated to be around 18 ft long. Traps were set and a large croc was caught and drowned in the nets. He was stuffed and toured Australia. He was a little shorter than people had thought. One unusal thing he had no scarring on his mouth, yet he attacked running propellors. This croc can be seen at the Darwin museum.
A few years later, a large male croc was caught in the same river system. He was missing about 1 foot of tail, but still measured just under 18 ft. He was named Caseus and is one display at Green Island, Cairns. Caseus's face is covered in scars which resemble prop cuts from an outboard. Also, every time he heard an outboard motor at Green Island, he would react as if it annoyed him.
So will the real sweatheart please stand up. Was it the one they caught, drowned and toured around Australia that has no scarring and was far shorter than all the witnesses claimed, or is it Caseus at Green Island who was the correct size, had the prop scarring and hates outboard motor noise.
