How do fish defend themselves from pollution?

Most people are aware that pollution is a problem in our oceans, but what they may not realize is that fish are also affected by this issue. There are many ways that fish defend themselves from pollution, but the most common method is by using their gills.

Gills are a type of respiratory organ that helps fish exchange oxygen and carbon dioxide. They are extremely efficient at this task, but they are also very sensitive to pollution. When fish are exposed to polluted water, the pollutants can damage the gills and make it difficult for the fish to breathe.

In order to protect their gills, fish will often use a special mucus that covers and protects the gills. This mucus is constantly being produced by the fish, and it helps to keep the gills clean and free of harmful pollutants.

Another way that fish defend themselves from pollution is by avoiding areas that are known to be polluted. Fish are able to sense pollutants in the water and will often swim away from areas that are contaminated.

Finally, fish also have a special type of immune system that helps them fight off infections and diseases. This immune system is constantly working to keep the fish healthy, and it can also help to protect the fish from the effects of pollution.

Overall, fish have a variety of methods that they use to defend themselves from pollution. These methods help to keep the fish healthy and to ensure that they can continue to thrive in our oceans.

Additionally, changes in water temperature can also cause fish to become sick. If the water is too cold, fish can become stressed and their immune systems can be weakened. If the water is too hot, fish can overheat and die.

By using their gills to filter out bacteria and parasites, secretions to ward off predators and parasites, and their fins and tails to swim away from danger, fish are able to reduce the chances of becoming sick.
