3 Herbivore teeth
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.

6.2.3 Groups

The large group portrait came to commercial prominence in the 1880s, probably as a result of the widespread introduction of dry plate negatives.
