Issued by authority of the African country of Eritrea, this beautiful uncirculated crown features an African Rhinocerous. A Rhinoceros, commonly called a rhino, is any of five surviving species of odd-toed ungulate in the family Rhinocerotidae, all native to Africa or Asia. The Rhino is characterised by large size, one of the few remaining megafauna animals surviving today, with all of the species capable of reaching two thousand pounds or more in weight. Rhinos sport one or two horns on the center of the forehead, and when there are two horns, they are aligned one in front of the other. These herbivorous giants have a thick protective skin, formed from layers of collagen positioned in a lattice structure. They also share an acute hearing and sense of smell, but poor eyesight over any distance. Most rhinoceros live to be about 40 years old. A male rhinoceros is called a bull, a female a cow, and the young a calf; a group of rhinoceros is called a "crash".
