Finding Appropriate Water Quality

I recently saw “Finding Dory” and it was adorbs!  Baby Dory was super cute and I was glad to see Nemo and Marlin decided to stick by Dory’s side to help her navigate the world with a little companionship!  


However, there were some aspects of the movie that I found to be disconcerting – and it wasn’t the talking fish or driving octopus.  

If you’ve been reading my past few blogs, you might have an idea of what bugged me – water quality.  “Finding Dory” has provided us a great opportunity to talk about how water quality affects the animals we love.  As I explained before, water quality is not the same across the board.  Of course we all know that there is fresh water and salt water.  And most of us know that drinking fresh water will help to maintain a healthily functioning body, while drinking salt water will help you die.  There’s our first big clue to help us understand the importance of water quality. 

But, while it’s easy for moviegoers to understand that the movie is a farce because animals don’t speak English in real life (plus it’s animated, duh), it’s not as easy for them to identify the inaccuracy of a tropical reef fish crossing the ocean to spend time in a kelp forest while looking for her cartoon family.  


You see, Regal Blue Tangs, like Dory, are a very specialized type of fish that live in coral reefs in the Pacific Ocean.  They forage for their food from the coral and, in turn, help keep the coral healthy.  Kelp forests, on the other hand, don’t have corals reefs, so Dory would have been without food.  Put simply, Dory would not have survived her quest to find her parents.

And I think that’s what is most worrisome.  The misconception that any aquatic animal can live in any type of water habitat.  After all, that’s what led kids to flush their pet Nemos down the toilet so they could make their way back to the ocean. Never mind that toilet water doesn’t empty out straight into the ocean, just like aquarium pipes aren’t all interconnected between exhibits.  Never mind that humans have fresh water, not salty ocean water, pumped into and out of their homes. 

Water quality or the amount of salt, the temperature, pH balance, clarity, and more, is different throughout the ocean.  Just like air temperature, the combination of atmospheric gases, sunlight, humidity, and more is different on land.  Changes in any of those factors, on land or in water, can completely change the ecosystem and corresponding specialized organisms’ abilities to survive in it. If a marine animal like Dory loses its habitat, they can’t just simply move to another part of the ocean.  This is why it is important to understand water quality and how humans can help protect it.

That said, I loved Bailey the Beluga.  He was lovable in spite of his faulty echolocation.
