Australian freshwater crocodiles are endemic to tropical Australia. In some areas they share billabongs and rivers with saltwater crocodiles but unlike the latter, freshies are not known to attack humans. Instead they feed on fish, amphibians, bats and birds. Freshwater crocodiles have a longer and thinner snout and a straighter jaw line. This is one of the smallest species of crocodile with males reaching a maximum length of just 3m at around 30 years of age. Like all crocodile species, however, their embryos lack sex chromosomes and sex is instead determined by the average environmental temperature. Males develop if the eggs are incubated within the range of 31.7°C to 34.5°C; females develop at all other temperatures.
This freshie was photographed in Lilycreek Lagoon by Kununurra, the town which was used as a base when filming the recently released film ‘Australia’. Kununurra translates from the local aboriginal language as ‘big water’.
