David Attenborough attempts to animate the life of the ichthyosaur whose 200-million-year-old fossil remains were found on Britain's Jurassic coast. Using state-of-the-art imaging technology and CGI, the team reconstruct the skeleton and create the most detailed animation of an ichthyosaur ever made. Along the way, they stumble into a 200-million-year-old murder mystery - and only painstaking forensic investigation can unravel the story of this extraordinary creature's fate.
In this episode, Iolo investigates the courtship and nesting behaviour of birds, including the amazing courtship display of great crested grebes at a reservoir near Pontypool, the impressive sky dance of hen harriers in the dramatic Cambrian Mountains, how nuthatch use mud like cement to prepare their nest in a woodland near Harlech, and why long-tailed tits near Newtown are exceptional nest builders. On the Lleyn Peninsula near Trefor, he looks at why one colony of shags nest earlier than any others in Wales, and in Pembrokeshire he finds out where house martins nested before they used our buildings. Iolo also looks at the variety of places birds like to nest, from little ringed plovers on shingle banks along the River Tywi to puffins underground on Skomer.
There is plenty of food in the Pacific Ocean, but it is the challenge of finding that food that drives all life in the Pacific. In the voracious Pacific we meet a destructive army of mouths, a killer with a hundred mouths and the biggest mouth in the ocean.
At more than 1,200 miles, the Orange River is the longest in South Africa. Join as we trace its westward journey, bringing to its shores a diverse sample of African wildlife, large and small. From powerful swimming birds like the African darter, to flat lizards who inhabit the granite rocks of the mighty Augrabies Falls, it's the journey of life-bringing water passing through some of the continent's most diverse and dramatic landscapes.
Plants amazingly dominate this green world by employing poisons, recruiting defensive armies, feeding off the dead and using animals for pollination and seed dispersal. For predators this world presents exceptional challenges, not only in finding prey in such a tangled place, but in how to deal with the toxins that so many animals and plants are laced with.
Bees and ants work selflessly toward a common goal. Bonobos maintain social harmony through sex, while meerkats organize themselves with military-level discipline. What do these creatures all have in common? The basic recognition that their survival hinges on an ability to work and live together.
