A rhinos brain only weighs around 400 – 600 grams. Rhinos have relatively small brains for mammals this size.
#Rhinoceros foot skin#
A rhinos skin is around 1.5 – 5 centimetres thick and is formed from layers of collagen (the main protein of connective tissue in animals and the most abundant protein in mammals), positioned in a lattice structure (crisscrossed framework). Rhinoceroses are large, thick skinned animals that can grow to be between 3 and a half feet to 6 and half feet tall at the shoulder and they can weigh between 1 – 2 tons. Perissodactyl are herbivores which means they do not eat meat, they only eat vegetation, plants and grasses. The word ‘perissodactyl’ comes from the Greek language and means ‘odd-number finger or toe’. Sub-order Hippomorpha: Family Equildae – horses, zebra and asses Sub-order Ceratomorpha: Family Tapiridae – tapirs, Family Rhinocerotidae – rhinoceroses Perissodactyls are divided into 2 suborders, 3 families and 15 species which include: Horses and zebras are also members of this species, however, they are divided up again into sub-orders as you can see below: Rhinoceroses carry their main weight on the middle toe of each foot. ‘Odd toed ungulates’ are animals that have hoofs but have a reduced number of toes (usually 3 toes). Rhinoceroses are ‘perissodactls’, which means ‘odd toed ungulates’.
The White Rhinoceros is classed as Vulnerable, with roughly 14,500 remaining in the wild. The Indian Rhinoceros is endangered, with fewer that 2500 individuals remaining in the wild. Three of the five species, the Javan Rhinoceros, Sumatran Rhinoceros and Black Rhinoceros are critically endangered. Two species of rhinoceros are native to Africa and three to southern Asia.
This relates to the long horn or two long horns in the case of the White Rhinoceros and the Black Rhinoceros, which is perched on top of their noses. The Rhinoceros, often called ‘rhino’ for short is one of five surviving species of odd-toed ungulates in the family Rhinocerotidae.
