Read the passage. a 40-ton creature, spinning around and around in the water, was coming right at my boat. we could hear its fins slapping the water with each revolution. the brute exhaled, and salty water sprayed us before it dove again. the sight of its tail flashing past and barely missing the boat sent shivers down my spine. when it came to the surface again, we could have counted the barnacles on its enormous head. what type of animal is the writer describing? a. shark b. seal c. penguin d. whale
