When people make exotic animals such as tigers and chimpanzees into pets, tragic consequences often follow.

Caught in the Act brings you a selection of unbelievable scenes depicting extraordinary animal behaviour, together with the emotional accounts of the filmmakers who witnessed them, that will make you rethink what you know about the natural world! Amateur and professional filmmakers are always out in the bush, witnessing wildlife in its element…but every now and then, Nature throws out a wild card, and it all gets caught on camera! Andre Hartman certainly didn't expect to capture the footage he did when a 14 ft great white plunged right inside the cage with two divers!

Territoriality over mating rights is a powerful instinct in the animal kingdom, driving animals to cruel and unusual behaviour. With their extraordinary size and strength, a clash between southern white rhinoceroses becomes a brutal battle when mating rights are called into question. Even the gentle giraffe turns violent when it comes to defending a female - and that elegant neck can deliver a knockout blow! But the territorial battle witnessed by Gordon Dyer was nothing short of terrifying: a coalition of four fierce male lions savaging an older opponent for his territory. But not all of nature's battles are fought between mature males - amongst plains zebras, and altogether more sinister practice is employed to ensure a stallion's dominance. Jenny Papas gives her heartrending account of how a stallion killed the offspring of another male to preserve his own strong genes.

When predator and prey clash, the odds are stacked in the predators favour! But that doesn't mean hunting is an easy task - sometimes, the prey fight back! A gnu takes a lion for a spin, whilst a zebra leaves a prowling leopard cowering in his treetop refuge! But few prey animals show the resilience of the monitor lizard: in an extraordinary clip, a determined lizard stomps clear across a road with a 5 kilogram martial eagle digging its talons into its back! The bird is so surprised by its die-hard prey, all it can do is sit and squawk as its meal takes it for a ride!

Saltwater crocodiles are one of the most successful predators the world has ever seen. They out-lasted the dinosaurs and survived a catastrophic extinction event that wiped out the dominant species on the planet. A 200 million year-old biological design, perfectly engineered for the modern world. But how can a creature this primitive still be state-of-the-art? The answer lies beneath its skin - and that's where we take you. A rare dissection opens up the inner workings of this bio-engineered machine. The saltie's weaponry: perhaps the most powerful jaws since T-Rex. Its early warning system: built-in pressure detectors that allow this huge beast to strike in an eye-blink. Multi-tasking organs that give the croc a killer edge. And one of biology's greatest mysteries - was the crocodile once warm-blooded, like us? Of the 23 known species of crocodilian - the giant saltwater crocodile known as the 'saltie' is the unchallenged king. It can grow over 20 feet long...and weigh well over a ton! It's the biggest and most dangerous reptile in the world. Across the planet, croc horror stories, photographs and video circulate on the Internet. The man-eater that took two hundred humans off the coast of the Congo; the giant alligator that escaped the New Orleans Zoo and preyed on the victims of Hurricane Katrina. We will reveal that what little truth there is to these sensational stories usually comes down to a saltie attack. How do crocs navigate through the murkiest water? How can they survive hideous injuries and never suffer infection? Can they learn? Remarkable scientific experiments conducted exclusively for us prove that salties risk self-destruction every time they attack. We analyse the structural engineering of the greatest bite on the planet. But most remarkably, we investigate crocodile blood - so resistant to bacteria it may help cure some of humankind's deadliest diseases! We will witness the extraordinary facts behind a creature we once dismissed as a 'living fossil'.

The devastating tsunami that killed as many as 250,000 people in Asia has renewed a common -and controversial - theory that animals can somehow sense imminent disasters. For some, it’s local folklore, yet for others, it's scientific fact. Animal Omens will survey the stories worldwide, from oral legend to divisive laboratory studies, to find the unexpected answers. The overwhelming evidence not only points to a deceptively simple scientific explanation, but also suggests ways we can actually forecast future catastrophes.
