I love this story from Erik Brooks. I downloaded it from youtube.

It's great for practising listening comprehension but also to talk about similarities and differences. The story is about a polar bear and a penguin who live on opposite sides of the world. They are different but they also have some things in common...They live in cold places, they are vertebrates... Try to elicit some more answers from your students!
After your students have listened and discussed about the story, they can write some similarities and differences between Alex and Zina. I'd project it on the board and check the answers together. Since there are not so many similarities in the story, your students will have to use their previous knowledge about the animals.
