Amazon Giant Otters really are giants. At nearly two metres long from nose to tail, they are the largest of the world's otters, and certainly the most sociable, living in noisy groups of up to 20. Giant Otters are one of the top predators of the Amazon, the aquatic equivalent of the Jaguar. They are known as lobos del rio (the wolves of the river) because, like wolves, they hunt in packs. Oscar is six months old, one of a lively litter of four cubs. He lives in Cocha Salvador, a freshwater lake, in the Amazon Basin. Home is the Manu National Park in south-eastern Peru. Giant Otters are experts at high-speed underwater pursuit. They live almost entirely on fish, and together Oscar's family eat an amazing 25 kilos of fish every day! Though Otters are completely at home in the water, they must still spend the night, and breed, in underground burrows, or holts. So when the forest floods, the whole family must move to a new home on higher ground. Giant Otters are at the top of their food chain and have few natural predators. However, the murky lake waters do hide a very formidable enemy, the Black Caiman (a South American crocodile). There are more than 400 of them lurking in the lake and the biggest of them (more than 3 metres long) dwarf even Giant Otters. When there is a Caiman about, Oscar learns the importance of family.
