Do sharks and whales eat elephant seals?

yes. sharks regularly eat seals, it is in their muscle memory diet. i do not believe that a shark would eat a whale, it might try a taste but out of curiOSity, like how sharks attack humans, they are either confused are they are just curious, there are multiple reasons but those are the most assumed. killer whales eat Great white sharks so i would figure that a shark would be frightened by a whale.
