In 2005 the Natura gold coins feature the first theme in the "Giants of Africa" series: The Hippopotamus (Hippopotamus amphibius).
Hippos are gregarious animals, associating in herds of up to 4O individuals, consisting of an adult bull, a number of cows and their young. Young bulls are evicted from the herd upon reaching sexual maturity. Adult bulls are extremely territorial and one of the known ways used for demarcation of their territories is their characteristic way of defecating. They spray the faeces over a shrub or rock by the rapid flicking of their short tail.
Rivers and lakes, not necessarily very deep, with pools of slow moving water and banks with good quality grazing, are the ideal conditions for hippopotamuses.
Territorial fights amongst hippos, are vicious and very often fatal. Fights can go on for hours, each of the contenders trying to inflict deep gashes on their opponent with their razor sharp and enormous incisors. There are very few adult hippo bulls without scars. Lone bulls find refuge in their own pools from where they launch their attacks on a herd bull, in an attempt to take over his harem.
During the day they stay in their pools or on sand banks. At night they leave the water to search for feeding grounds, normally using the same route. Hippos are extremely aggressive and unpredictable animals, very often charging other animals, capsizing boats and even killing people. Hippos can weigh up to 1500 kg and their life-span averages 50 years.
This Natura Prestige Set, consisting of four gold coins, is packaged in a box made of indigenous South African wood.
