Episode 21 (Episode 8 in Series 2) Scotland: CARNIVOROUS HERBIVORES Off the shores of Scotland lie two remote islands where the introduced species of deer and sheep have found a sinister solution to surviving their harsh surroundings. These normally mild mannered herbivores are killing to satisfy their mineral deficient diet. Animal X investigates this unusual phenomenon for answers. Australia: GIANT MONITORS And in Australia we investigate the Megalania Lizard - a giant predator who would have been able to out-run a man and tear him to pieces. Thought to be extinct, the Megalania held court in the Australian outback for over 2 million years. Scientists believe this creature last walked these lands over 20 thousand years ago -- but there are others who believe it is still out there... International: ANIMAL MEMORIES And finally, Animal X investigates the amazing brainpower of animals that rely on memory to survive. We speak to the world's leading expert on animal cognition and one of the most prominent homing pigeon authorities in an attempt to answer the long standing question of whether animals are capable of episodic memory.
