Ice Drift: Figurative Language

In the book Ice Drift, an example of figurative language is “His ears were small, like those of most other Arctic animals, offering less area to absorb the cold of forty-five degrees below zero.” In that sentence on page 5 and chapter one the author uses a simile. I know that's a simile because it uses “like” to describe the dog, Jamka to Arctic animals. This simile lets us, the reader clearly visualize Jamkaś ears. And I know what Arctic animals ears looks like but not necessarily Jamkaś ears. Why I said that is because in the definition of simile in our notes says “A comparison of two unlike I things using like or as” I think the author used a simile in this spot, because he wanted to give his audience a good visual of Jamka the dog.
