I am back with another biology essay, so let’s get right to it. The topic I chose for this essay:
Think of marine mammals, which breathe air like we do but drink only salt water; and think of fish such as salmon which live part of their life in saltwater and part in freshwater. How do aquatic organisms deal with the different concentrations of salt in the water?
As I’ve mentioned in my last essay sea creatures such as fish/sharks have gills to not only breathe underwater, but handle the salt levels of the ocean. Not just fish but any marine mammal that lives and is able to breathe underwater, handle the salt levels of the ocean. All of them are different and are built to be adaptable in the aquatic environment. Some fish that live in the saltwater have a special gland in there kidneys that helps process the salt making them not dry out.
Creatures that are able to breathe oxygen and live around the saltwater have adapted to these aquatic conditions as they were designed so that way. For example, sea birds that dive into the saltwater have special glands behind their eyes that allow them to circle out the salt so to not dry them out. Other mammals that can live on land and function in the saltwater have similar features.
Thanks for reading this essay. I hope you liked it or learned something new from it! I’ll post my last biology essay soon and as always have a great rest of your day!
