The parcel was from Uncle Bob. The faucet was fixed yesterday. The faucet is dripping today. The store is close to our house. The store is a grocery store.
Many people find fish and other underwater creatures strange, as well as interesting.
We probably don't look all that interesting. We can't swim underwater for very long, and we must look very odd with two arms, two legs, and a head that all seem to be attached to a square torso. Yet fish, like humans, belong to the same major group of animals called vertebrates. Vertebrates also include reptiles, amphibians, and birds. All vertebrates have an inner supporting skeleton, usually of bones, including a main backbone.
