‘a malay weasel (Mustela nudipes) in borneo. only a few dozen camera-trap photos of this species have ever been recorded, revealing only snippets about its ecology. for one, the species is diurnal, whereas most weasels are nocturnal.’
Documented cases of deer (and other “strict” herbivores) munching on carrion or killing and eating small, weak animals (such as baby birds) are not entirely uncommon, though people are frequently shocked to learn that it occurs. It is speculated that some deer may crave calcium or other minerals which they can get from eating the bones of animals, or they may resort to consuming animal protein when they can no longer find plant proteins in the wild. This deer ate all 4 legs off of a frozen rabbit that was left out as bait for coyotes.
Although strikingly cat-like in their appearance, fossa belong in the mongoose family. With a nose-to-tail length reaching up to 6 feet, they are the largest carnivore endemic to Madagascar. These stealthy creatures are excellent hunters, and one study showed lemurs constitute over 50% of fossa diet.
