Bonobos are more slender, have longer hind limbs, short clavicle, small molars. 50 to 200,000 chimps and bonobos in fifteen countries, a further nine countries now extinct. Both species are moderately sexually dimorphic, with males weighing 30% more than females. All pan rely on the forest to some extent, but especially bonobos, who live only in lowland rain forest and swamps. They are omnivorous, with mostly plant foods in their highly varied diet. Chimps eat from as many as 20 plant species a day, up to 300/year. They eat fruit mostly, eating one large meal, resting for an hour or two, then moving on. Animal prey equals approximately 5% of their feeding time in some groups.
