Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths, relying instead on their lips to pluck food. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary.
They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm) protective skin formed from layers of collagen positioned in a lattice structure. Rhinoceros 6 free Members of the rhinoceros family are some of the largest remaining megafaunas, with all species able to reach or exceed one tonne in weight. For modeling on the Rhino 3d software environment, a network of curves are created first in space and then converted to a surface. Rhino 6 free download is available for windows 10,8,7 (32/64 bit ) which any of you can use it by downloading and installing on your pc and labtop. The principles of building surfaces in Rhino are based in the construction of curves.
