In the previous two chapters, we started exploring vertebrates. So far, those vertebrates have had skeletons made of cartilage. From here on, through Chapter 38, the vertebrates have harder, bony skeletons. This chapter focuses on the bony fishes.

By the way, now that the term has been used, let's discuss the term "fishes". Most people know that the plural form for a group of fish is just that, "fish". "A school of fish" is the correct way to say that there are multiple fish gathered together. But the scientific assumption with that usage is that the school of fish is made up of fish of the same species. It could be a school of herring, for instance.

But picture a reef where there are a lot of different fish species gathered together. In this case, the term used to describe this community is "fishes". So "fish" is used to describe multiple fish of the same species and "fishes" is used to describe multiple fish of different species. At least that's how this guide will use the terms.
