於馬達加斯加一個小型自然保護區，頂級捕食者馬島獴被發現捕食極度瀕臨滅絕的冕狐猴。馬島獴屬易危物種，通常捕食囓齒類、鳥類或野豬等較小型的動物。冕狐猴是冕狐猴中體型最大的物種，但由於保護區被農地包圍，棲息地被孤立，近親繁殖削弱了冕狐猴的健康及數量，令牠們更容易成為馬島獴的目標。

Critically endangered diademed sifakas are being hunted by vulnerable fosa, the top predator in a small nature reserve in Madagascar. Fosa usually preys on smaller animals like rodents, birds or wild pigs. The diademed sifaka is the largest sifaka species, but because the nature reserve is surrounded by farmland and became an isolated habitat, inbreeding has weakened the sifaka’s population, and they became easy target for the fosas.
