When you walk past the tanks in an aquarium store, you see both physostomous and physoclistous fishes. Goldfish, for example, are physostomous, and cichlids (such as the popular convict cichlid) are physoclistous
Conduct a thought experiment comparing the responses of the two kinds of fishes to changes in air pressure. (Don't actually do this because it would be painful for the fishes.) a. Imagine that you put a goldfish and a cichlid into a jar half filled with water and then screwed on a lid to make an airtight seal. Protruding from the lid is a tube to which you can attach a vacuum pump and a valve that allows you to close off the tube. b. Pump some air out of the jar. What effect will doing that have on the air pressure inside the jar? How will each of the fishes respond to that change in pressure? How are those responses related to being physostomous or physoclistous? c. Now open the valve and allow air to enter the jar, returning the pressure quickly to its starting level. How will each of the fishes respond to this change in pressure? How are these responses related to being physostomous or physoclistous?
