Each one of our custom defenders USA is created around a particular wild animal from the African planes. "Imbuvu" is Zulu for Hippopotamus. Despite being vegetarian, hippos are considered the most dangerous terrestrial animal on the African continent. On average, they are responsible for the deaths of almost 3,000 humans every year. Male hippos are exceptionally territorial and will actively defend their section of river or lake from perceived intruders. Females will attack any animal that comes between them and their offspring. Hippos can run at speeds of over 30 km on land, and may weigh over 3,300 lb/ 1,500 kg. A male hippo's canine teeth can exceed 20"/ 50 cm. Custom defenders USA.
