Chapter 24, Problem 1FFT
Summary Introduction
To describe: The behavioral and physiological changes that occur when a fish migrates from a freshwater stream to the ocean.
Introduction: Water, as well as dissolved ions, continuously moves by diffusion and osmosis across the gill membranes present in fishes. These gill membranes are permeable, which helps in the movement of water as well as dissolved ions.

- In the aquatic world, osmoregulation is very important. Please describe what would happen at the cellular level as well as organismal level to a freshwater fish that is placed in salt water.arrow_forwardThe bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.) By actively transporting ions out from the gills into the water? 3.) by excreting highly concentrated urine? 4.) by resorbing ions in nephronsarrow_forwardRegarding the function of nephrozoan nephridia, would you expect the final urine of a freshwater species to contain more or less water than the final urine of marine species? Explain.arrow_forward
