Crocodiles in Darwin Harbour, 1995. NFSA title 284693

Saltwater crocodiles, or ’salties’, are the largest and most aggressive of all crocodile species. Fully grown they can live for up to 70 years, average four to five metres in length and weigh up to 500 kilograms. As with the box jellyfish, crocodiles are a dangerous reality in the Darwin region, particularly if they take up residence in popular swimming spots, as this ATV 10 news item explains.
