It's not just humans that make predictions on the World Cup. 

The animal oracle predictions have begun and loggerhead turtle "Big Head" is giving its host nation a big boost. 

The animal predicted Brazil will beat Croatia in the opening game of the World Cup 2014 on Thursday. The turtle was given the choice between eating fish hung from a Brazilian flag and a Croatian flag. Onlookers cheered as the sea turtle chose the fish representing Brazil. Four years ago, Big Head's predecessor from Germany, Paul the Octopus, predicted 11 out of 13 games correctly and started a craze about animal psychics. 

Let's see if Big Head can match Paul's accuracy.
