A 20ft saltwater crocodile that may be the world's largest in captivity has not eaten since it was captured in the Philippines.

Officials are closely monitoring the croc nicknamed "Lolong" six days after his capture in a creek near southern Bunawan township drew worldwide attention.

Wildlife official Ronnie Sumiller who led the hunt said that it's normal for crocodiles to be stressed after being trapped and handled. Even in the wild, they don't normally eat daily, and a crocodile as huge as Lolong can go without food for up to six months.

Lolong has been placed in a 8,611sq ft pen secured by 4ft tall concrete walls topped by welded wire.
