Fearless Costa Rican fisherman Chito playfully wrestles in the water with his best pal Pocho (the name means strength), a deadly 17ft crocodile.
The 52-year-old daredevil draws gasps of amazement from onlookers by wading chest-deep into the water, then whistling for his 980lb buddy and giving him an affectionate hug.
Chito made friends with the croc after finding him with a gunshot wound on the banks of the Central American state's Parismina river 20 years ago. He had been shot in the left eye by a cattle farmer and was close to death. The fisherman enlisted the help of several pals to load the massive reptile into his boat.
He says, "When I found Pocho in the river he was dying, so I brought him into my house. He was very skinny, weighing only around 150 lb. I gave him chicken and fish and medicine for six months to help him recover. I stayed by Pocho's side while he was ill, sleeping next to him at night. I just wanted him to feel that somebody loved him, that not all humans are bad.
"It meant a lot of sacrifice. I had to be there every day. I love all animals, especially ones that have suffered."
It took years before Chito felt that Pocho had bonded with him enough to get closer to the animal. He says, "After a decade I started to work with him. At first it was slow, slow. I played with him a bit, slowly doing more. Then I found out that when I called his name he would come over to me."
At one point during his recovery, Chito left the croc in a lake near his house. But as he turned to walk away, to his amazement Pocho got out of the water and began to follow him home.
Chito recalls, "That convinced me the crocodile could be tame." But when he first fearlessly waded into the water with the giant reptile his family was so horrified they couldn't bear to watch. So instead, he took to splashing around with Pocho when they were asleep.
Four years ago Chito showed some of his tricks to friends, including getting the animal to close his eyes on command, and they convinced him to go public with a show.
Now he swims and plays with Pocho as well as feeding him at the lake near his home in the lowland tropical town of Sarapiqui. The odd couple have now become a major tourist attraction, with several tour operators take visitors on touring cruises to see the pair.
Chito will quietly call for Pocho, who announces his presence by thrashing around, lifting his tail and head above the water. Chito tells the onlooking tourists: "This is a very dangerous routine but Pocho is my friend and we have a good relationship. He will look me in the eye and he does not attack me. It is too dangerous for anyone else to come in the water. It is only ever the two of us."
