Do hyenas eat hippos

Hello, that is a very interesting question.

I highly doubt that one hyeana could kill, or eat a hippo.

Even a bunch of hyeana's would have a very hard time killing, or eating a full grown hippo. They may be able to catch a baby hippo, but that would also be hard because the mother would probably be around. Even Lion pride's have a hard time taking down hippo's, most of the time one lion or more gets injured or hurt and the whole pride runs away, therefore I highly doubt even a bunch of hyena's could take down a hippo even with there sneaky and cunning instinct.
