Freshwater crocodiles — the Australia Zoo has many — are a harmless species. There has never been a fatality as a result of a freshwater crocodile attack in Australia's European or Aboriginal history. They are predominantly fish eaters and don't consider people likely prey, as humans are much too large.

The maximum length for a male is about 10 feet, while females rarely exceed 7 feet. The average life span for a freshwater crocodile is about 70 to 80 years. Northern Australia is the only place in the world where this species can be found in the wild.

Old Yella is a dominant male freshwater crocodile who is 8 feet in length and approximately 50 years of age. He is very yellow in color with large teeth and a surprisingly aggressive nature. He commands a lot of respect from the other seven crocodiles in his enclosure. Prey he would target in the wild include turtles, water birds, fish and crustaceans, or maybe even joey kangaroos and dingo pups if he were lucky.

Muddy, the second male in the enclosure, is 7 feet long, 175 pounds and 45 to 50 years old. Dark in color, Muddy is always hungry and is most often found in the middle of the action.

Xena, the largest female freshwater crocodile at the zoo, is 6 and a half feet long and 150 pounds in weight. She is relatively quiet, but still the most dominant of the females. She is the main defender of the nest area.

Terri is 6 feet long and weighs about 110 pounds. She is very greedy and is always looking for food. She is often on a diet to reduce her weight.

Gondwana is the smallest female at 4 feet long and about 65 pounds in weight. Because of her small size, Gondwana is very quick. She also heats up faster then the others, which helps her strike quickly at food.

Martina, at 40 to 50 years old, is one of the quietest freshwater crocodiles at the Australia Zoo. She allows the keepers to pat her and they can work easily around her.

Tash, also 40 to 50 years old, is another quiet girl who is very easy to work around. She tends to keep herself away from the other freshies in the group.

Meagan has an aggressive attitude when it comes to food. She will jostle all of the others out of the way to get the first share. Otherwise, she is generally an even-tempered girl.

Blondie was caught from the Leichardt River in the early 1970s. She is a very beautiful golden yellow color, which kept her camouflaged in her natural environment. She is a good girl who can get very excited over food.

Mr. Freshy was caught in the Moorehead River in Cape York in the 1970s by Bob and Steve Irwin. For 100 years Mr. Freshy was the dominant male freshwater crocodile in the river, as well as the sacred or token animal to a local tribe of Aborigines. They swam and fished alongside of him for two generations without conflict.

In the early 1970s, hunters shot Mr. Freshy twice. One hit him in the right eye, which is now missing, and the other got him in the base of the tail as he dove to get away. Bob and Steve rescued Mr. Freshy after the Aborigines called on them to help this aging and hunted crocodile.

Bob and Steve brought Mr. Freshy back to the zoo so that he could be rehabilitated and live out the rest of his life there with his blonde girlfriend. Mr. Freshy is estimated to be about 130 years of age.
