Seals are a lot bigger than mackerels. It is far more likely for a seal to eat a mackerel than the other way around.
Yes, some species of sharks do eat mackerels. Mackerels are a common prey for many shark species due to their abundance and high nutritional value. Sharks use their sharp teeth and powerful jaws to capture and consume mackerels as part of their diet.
Mackerels are saltwater fish. Tadpoles live in freshwater. Meaning a mackerel wouldn't have much chance of eating tadpoles.
