Felids like the tiger may also prey on bears, [115] [116] particularly cubs, which may also be threatened by canids. [14] [101] Bears are parasitized by eighty species of parasites, including single-celled protozoans and gastro-intestinal worms, and nematodes and flukes in their heart, liver, lungs and bloodstream.
