Top best answers to the question «Are dolphins and sharks analogous structures»

Both dolphins and sharks swim after prey in the ocean. Streamlined bodies and fins provide a big advantage for them, allowing them to swim faster… Since dolphins and sharks occupy similar niches and face similar challenges, similar adaptations have been advantageous to them, resulting in their analogous structures.


Those who are looking for an answer to the question «Are dolphins and sharks analogous structures?» often ask the following questions:

🌴 How are whales and dolphins examples of analogous structures?

  • These structures can be traced back to the last common ancestor that the animals shared.
