    The estuarine crocodile (Crocodylus porosus) is a semi-aquatic reptile, living mainly in rivers, mangroves and estuaries. Its geographical range extends more than 10,000 km2 of the South-East Pacific, from East India to Fiji and from southern China to North Australia. Although it spends most of its life in saltwater, it cannot be considered a marine reptile in the same way as a turtle is, for example, because it relies on land for food and water.

    The results explain why, despite occupying such a large range, species diversification of the estuarine crocodile has not occurred.

    One satellite-tagged crocodile – a 3.84 meter-long male – left the Kennedy River and travelled 590 km in 25 days down the west coast of Cape York Peninsula, timing his journey to coincide with a seasonal current system that develops in the Gulf of Carpentaria.

    Wide ranged amphibians never evolve. Thanks for the heads up

    Actually, as long as they are able to share genes, they don't "diversify". They don't evolve into separate species.

    So that whole thing about evolving from the sea and becoming amphibians is total bullshit?

    Frank, try reading a few of Ernst Mayr's books. Perhaps then you will not seem so damned ignorant of the mechanisms of evolutionary biology. A few of Jay Gould's books would help, also.

    That's what it sounds like to me.

    Sure, right after you read the Case for Christ and the Human Genome Project results.
