Black-and-white ruffed lemur

Often called the world's largest pollinator. In Madagascar's rainforests this lemur feeds on the big flowers of the traveler's tree, Ravenala madagascariensis, pushing its long snout deep inside to reach the nectar and coming away with pollen on its face and fur for the next tree. Fruit makes up most of its diet, but when fruit is scarce it can spend up to 72% of its foraging time on nectar. The flowers seem shaped to fit a ruffed lemur's face, a sign of how long the two have been evolving together. All three subspecies are listed as Critically Endangered, so the traveler's tree is at risk of losing one of its main pollinators in the wild.
