All fish have gills, and some also have lungs (e.g. lungfish). Imagine that a fish evolved that did not have gills or lungs. Consider the physiological role of gills and how aquatic animals that do not have gills are able to survive. Answer the questions below: a. (1 mark) What might the size and shape of this fish be like? b. (1 mark) What sort of environment would you expect this fish to live in? c. (1 mark) How do you expect the life history of this fish would differ from that of a "typical" fish. Note that here, "life history" broadly refers to the actions of an animal related to survival and reproduction. All fish have gills, and some also have lungs (e.g. lungfish).
