THE GIANT OTTER (Pteronura brasiliensis)

Hunted to the verge of extinction a few decades ago for their priceless fur these endearing animals are now restricted to a few areas of undisturbed waterways in Amazonia and are strictly protected. With a population density of 0.5 people per square kilometre (the lowest in Peru), Madre de Dios harbours one of the country's last viable populations of giant otters.

Otters are voracious hunters, consuming up to 4 kg of fish daily, and have no natural enemies. They are very sociable and generally live in groups of between 2 and 10 individuals. During the dry season (June to November) the young are born, and during this period they are very difficult to observe. The young will stay with the group for around 3 years before setting out alone in search of their own territory and a mate.

Giant otters are seen on the lakes only occasionally, and are a delight for those lucky enough to spot them.

If a group is spotted try not to make any noise or sudden movement. They are usually very inquisitive creatures and will often approach a canoe to within 20 or 30 metres. Please do not pursue them!
