    Australia's deadly saltwater crocs are making a dramatic comeback. They're spreading in alarming numbers through the billabongs, rivers and beaches of the Northern Territory. Last year, over 300 had to be removed from the harbour of Darwin, the region's capital. Hundreds of cattle are being killed, and most worrying of all, attacks on people are increasing every year, often in places where crocs were previously unknown. Biologist Adam Britton tries to find out why the crocs have suddenly become such a problem

  11. Natural World Season 33 Episode 9 - Killer Whales: Beneath the Surface
    6.4/10(7 votes)
    S33:E9

    The killer whale was long feared as a sea monster until, in May 1964, one was brought into captivity for the first time. This spawned a journey of discovery into the killer whale's true nature. It quickly became clear, these were not mindless killers - they were, in fact, highly intelligent social creatures. Today, our understanding is deepening still further and the latest revelations are among the most sensational - not only will these top predators 'adopt' and care for injured and abandoned orphans, but it seems there's no longer just the 'killer whale'.

Marine biologist and film-maker Rick Rosenthal has travelled three oceans in his attempt to capture them all on film, and in doing so has become a passionate champion for these endangered yet little-known ocean giants.

  14. Natural World Season 3 Episode 10 - Wild Ireland
    6.8/10(9 votes)
    S3:E10

    Time, climate and the needs of the Irish have fashioned a magical island. Cast free when the ancient bridge from Britain sank, it still holds within its saucer of ice-scoured rocks the animals and plants that followed the retreat of the glaciers. There are Irish deer, Irish stoats and Irish mountain hares, but no snake ever came to trouble the people who cut the forests, fished and farmed. They invented a land of fairy tales, but there are real mysteries too: a strange meeting of the Arctic and the Mediterranean in a moonscape of white rock called the Burren; the unbroken ebb and flow of wildfowl from this mild winter haven; and the daunting sprawl of the bogs - unbeautiful to some, yet valuable to all, fragile wildernesses in a land wild with change.

And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
