What I learnt (in checking for this clue) is that there are marine ungulates too, including dolphins... but I thought using a dolphin as an example of a hoofed mammal would be just a tad too confusing!!
I didn't know that either, but I guess it makes sense: they evolved from some hoofed creature even if they don't have the defining characteristic any more.
