A friendly wild crocodile floats over to locals to be patted on the snout and be fed pieces of fish.<br /><br />The huge estuarine crocodile has been living in a river in Bontang City, East Kalimantan, Indonesia, for more than two decades.<br /><br />Residents have nicknamed the reptile Riska and she has become so used to humans, that she gently paddles over to greet them.<br /><br />Footage shows one of the neighbours patting Riska's back, splashing water on her nose and dropping a fish into the croc's mouth.<br /><br />Despite the menacing appearance of the beast's eyes glaring up from the water, she has become friendly to humans.<br /><br />"She's such a big crocodile, look at her turning her body," says a man in the video. ''Take it easy my friend, see you next time.''<br /><br />A local fisherman, named Ambo, said that he has been feeding Riska for at least 20 years since noticing the juvenile croc in the Guntung River.<br /><br />Ambo said: ''It's been a long time. Now Riska's age is probably around 23 years. She's about four metres long." <br /><br />The fisherman said he considers Riska to be a part of the family as well as a guardian of the surrounding community.<br /><br />Ambo said he named the crocodile Riska after his wife had a dream about the reptile.<br /><br />"The crocodile came to my wife's dream. She said to my wife 'hello, my name is Riska', so that's where the name originated," Ambo said.
