The Greater Bamboo Lemur (Prolemur simus), also known as the Broad-nosed Bamboo Lemur and the Broad-nosed Gentle Lemur, is the largest bamboo lemur, at over five pounds or nearly 2.5 kilograms. It has greyish brown fur and white ear tufts, and has a head-body length of around one and a half feet, or forty to fifty centimeters. It feeds almost exclusively on the bamboo species of Cathariostachys Madagascariensis, preferring the shoots but also eating the pith and leaves.
