Rio de Janeiro: If Zika-spreading mosquitos sound like the deadliest bite at Rio, look out for the crocodile-like caimans on the Olympic golf course. Beware also of the capybaras rodents, monkeys, three-toed sloths, burrowing owls and the occasional boa constrictor.

Rio is famous for wild life at Carnival time, but real wildlife will bare its teeth during the 72-hole men's and women's tournaments over the next two weeks.

PGA Tour players have faced crocodiles on courses before in Florida. But in Rio, there are signs to warn spectators and players to be cautious around the wild animals roaming the Olympic course, not the least of which are the caimans, the crocodile cousins who are well-known predators on South American lakes and streams.
