Step 1
These include: * **Large liver:** The liver of a shark is filled with oil, which is less dense than water. This helps to reduce the shark's overall density, making it easier to float. * **Cartilaginous skeleton:** Sharks have a skeleton made of cartilage, which is Show more…

Compare and contrast how salt and water balance is maintained in freshwater fish, saltwater fish, and sharks.
Sri K.
Fish species have special adaptations to maintain osmotic balance in their environment. They must adapt to their surroundings, determining whether the fish is hyperosmotic, hypoosmotic, or isosmotic to the water. Begin by explaining how the fish gains - Then describe at least two mechanisms by which the fish either gains or loses salts or water to maintain this balance.

QUESTION 1. 1a. For the two fish (teleosts) shown below, indicate whether each fish is hyperosmotic or hypoosmotic relative to its environment. Freshwater Fish Marine (Saltwater) Fish Relative to its environment, this fish is: hyperosmotic / hypoosmotic Relative to its environment, this fish is: hyperosmotic / hypoosmotic 1b. Draw an arrow on each fish indicating whether free water moves into or out of the fish. 1c. Across what 2 surfaces in contact with the environment does most water movement occur? and 1c. For each fish, compare strategies that will help to maintain water balance. Urine production: lots / little lots / little Ingestion of water: lots / little lots / little 1d. To maintain ion balance, how should chloride cells move ions across the gills? into / out of the fish into / out of the fish
