Structure and Function in Fish. Fish are aquatic vertebrates. They make up more than half of all vertebrate species. They are especially important in the study of vertebrate evolution because several important vertebrate traits evolved in fish. Fish show great diversity in body size.There are many species of Chinese freshwater fish that live 2–4 years; anadromous salmon generally live 3–6 years; many medium and large freshwater fishes, such as black carp, grass carp, silver carp, and bighead carp, generally live 7–8 years. Few fish live more than 10 years old, but some can live up to 15–20 years.Help desktop support has come a long way since its inception.
