Why Do Dead Fish Float?: Learning about Matter with the Garbage Gang by Thomas Kingsley Troupe

This is my first introduction to The Garbage Gang. I suppose I might have missed something as to how this group came into being and why. That said, I did enjoy the presentation. Nice illustrations presented in a comic book cell format. Might be a little over the heads for little ones. I am thinking detail minded, science minded 2nd or 3rd graders.
This title was about the different states of matter and does answer the question that made you pick up the book in the first place - Why do dead fish float?

Why do fish float when they die?

You see your fish floating on their side in the aquarium or notice that they jumped out of the tank. While your first reaction might be to grieve or start to dispose of the body, your fish might not be dead. You can take measures to know one way or the other by checking your fish's vital signs, dealing with a dead or dying fish, and considering other issues in fish who only look dead.

why dead fish float upside down

But why do they float upside down when they decide it's time to take a ride on the porcelain express? The answer to this question has a lot to do with how they maintain proper buoyancy when they're alive. As you may or may not know, most fish are in possession of an organ commonly known as a "swim bladder". This organ can be filled or emptied of air by a fish at will via its gills, allowing them to either float higher, sink lower or stay suspended at about the same depth, not unlike a Buoyancy Compensator BC used by scuba-divers. Although swim bladders are critical to a fish's ability to float, sink or hover without expending much energy , they have the unfortunate side effect of making them rather unstable. To explain, research has shown that the relative position of a fish's "centre of buoyancy" is, amongst fish with swim bladders, almost universal located below their centre of mass near their stomach, making them quite prone to hydrostatic rolling which is just a fancy way of saying it makes them more likely to go belly up. This is why fish can often be seen flapping their fins, even when they're not moving and in perfectly still water.

Have you ever found your pet goldfish floating listlessly at the top of the tank on its side? Most people who make this discovery assume that little goldie has passed on to the other side and immediately scoop him or her from the tank and toss them in the toilet for a traditional goldfish funeral. Unfortunately, in many cases the fish isn't actually dead, but rather suffering from a problem with their swim bladder due to over feeding. There are plenty of warnings about over feeding fish, but many people are unaware of just how easy it is to over feed. The danger of over feeding is that it can lead to constipation, which can in turn lead to problems with the fish's swim bladder. The swim bladder is an organ that is flexible and filled with gas.

If you've seen dead fish in a pond or your aquarium, you've noticed they tend to float on the water. More often than not, they'll be "belly up", which is a dead giveaway pun intended you're not dealing with a healthy, living fish. Have you ever wondered why dead fish float and live fish don't? It has to do with fish biology and the scientific principle of buoyancy. To understand why a dead fish floats, it helps to understand why a live fish is in the water and not on top of it.
