The flippers of a whale and the fins of a fish are examples of analogous structures.
Explanation:
They perform the same function (swimming).
They have different evolutionary origins and internal structures.
Whale flippers evolved from mammalian forelimbs.
Fish fins evolved independently in fishes.
So, despite their similar function, they are not derived from a common ancestral structure.
