Fish are able to breathe underwater because of various adaptations to the water's salt content and osmotic pressure, as well as the physical evolution of gills;
in other liquids, these factors (among others) would not be the same and would therefore not be conducive to survival
.
Can a fish breathe in blood?
This process of breathing begins when a fish gulps water through its mouth. The water enters the mouth and passes through the feathery filaments of the fish's gills, which are rich in blood. These gill filaments absorb oxygen from the water and move it into the bloodstream.
Can a fish breathe in milk?
The simple answer is “
no
,” but the nuanced response sheds light on how fish, and all other organisms, function. Fish have evolved over many millions of years to survive in water with a certain amount of dissolved oxygen, acidity, and other trace molecules.

By making alcohol, crucian carp and goldfish can survive where no other fish can
, meaning they can avoid predators or competitors.
Can a fish drown in chocolate milk?

. Marine fish are what's called hypertonic to the seawater. So essentially, they lose water through their gills to the seawater. The seawater is saltier than their blood.
Can fishes feel pain?

Can a fish drown by swimming backwards?

yes, they can
.
Can you get your fish high?
Scientists Have Been Getting Fish High Since The '70s
!
That results of that study, which appeared in the journal Pharmacology, indicated that THC was, in fact, a “strong suppressor” of aggressive behavior. But after about 10 treatments of THC-laced food, the fish actually developed a tolerance to weed!
Can fish drown water?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate.
They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen.
Can fish survive in swimming pools?
While some homeowners are decorating their property with water effects featuring live fish — such as koi ponds —
adding fish to your swimming pool is not the answer
. The biggest problem is that the water that is safe for humans to swim in is generally toxic to fish.
Why can't fish breathe on land?
In water, the projections on the gills float, so each is surrounded with water from which it can absorb oxygen.
On land, these all collapse together, blocking most of the surface area
. So they don't work well and the fish suffocates. Lungs increase surface area by having many tiny pockets, which don't collapse in air.
Can a dog get drunk?
Dogs can get drunk when they drink excessive alcohol
. The smaller the dog, the smaller amount of alcohol is needed to get him drunk. A drunk dog will exhibit behavioral changes. Just like humans, they will have problems walking or standing up due to loss of balance and lack of coordination.

; this can frequently occur if you leave a goldfish in a small bowl without a running filter.
Can fish swim juice?
Fish Breathing In Other Liquids
In a substance like Coca-Cola or orange juice, the solute concentrations would be extremely different than in water, and there would likely be less dissolved oxygen in these liquids, essentially suffocating the fish.
Do fish ever fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart
.
Do fish get pee?
Fish urinate either through their gills or through a “urinary pore.”
The latter eliminates urine that has been filtered via the kidneys. Saltwater varieties excrete most urine through the gills, while freshwater fish do so through the urinary pore. Saltwater fish take in a great deal of salt and must excrete it.
Do fishes go to sleep?
While fish do not sleep in the same way that land mammals sleep,
most fish do rest

Why is electrofishing done at night?
1) Safety – although the field of electricity is very localized to the front of the boat, between 250 and 500 volts is directed into the water, generally at 4 to 6 amperes. Electrofishing surveys are done at night
when the lake is quiet and there is less chance of people or pets swimming in areas being surveyed
.
Do fishes feel love?
What they found was that both the female and the male she had chosen were slower to spawn and became a little more glum. This shows us that

Sharks are the only fish that can't swim backwards
— and if you pull a shark backward by its tail, it will die.
Can fish see in dark?
Most fish can see in the dark due to evolved cone cells in fish eyes
. But still, you must turn off the aquarium light for at least 12 hours to give fish time to rest. Some fish can see in the dark better than others because of differences in the number of cones present in each fish species.
Can u drown a shark?
Is it possible for a shark to drown? Despite being ocean dwellers, most sharks need oxygen to breathe. They don't have lungs but instead absorb oxygen from the water using their gills.
If there's not enough oxygen available in the water, sharks can't breathe and can easily drown
.
