First off you already made a thread like this.

Second off I fucking answered you. I gave you a logical, honest answer. Can we be done?

So you're not satisfied with physics? Seriously consider floating in water. You don't have to do much. Even if you're sinking you just wiggle your arms a little and up you go. Now consider waving your arms enough to get airborne. It's a lot more work to stay up in the air then it is to stay afloat in water.

If a fish were to swim in air their fins would need to produce lift, like a heavy downward motion to propel them upward and to keep them upward. Birds and bats and insects have these massive pec muscles (think about that turkey breast, so much muscle) that help them move their wings with enough power to get past gravity and up into the air. Most fish in water don't have these massive pecs and just have muscles that move their tail fin side to side.

If a fish were to swim in air, they would have to be going torpedo speed to begin with because they wouldn't be able to get up. Flying fish accomplish this by swimming fast and with one tail flick they're up in the air, but their fins lack the muscle to keep them afloat, and so they glide back down into the water. No upward movement. No flapping.

Are we happy now? Its seriously just physics.

Because being able to adapt and survive in a marine environment is more than enough. The ability to move from the water where food is plentiful for many species of fish to the air where, in the middle of the ocean, you're going to get fuck all is pointless.

No selection pressure, no evolutionary force. The best you get are fish who can exit the water for a short period of time to escape predators but quickly drop back in.

Enjoy your biology answer.

wrong, if there were as many fish in the air as there were in the water, then there would be evolutionary pressure.

Your "air fish" are called "birds".

Consider the need for air-breathing lungs and gills if changing environment, plus the immense musculature required to fly in the air as opposed to the ground. Think of a bird's wings compared to the size of a fish's fins. Then there's the flaw of having lungs that have large open spaces in them for efficient oxygen processing when you're under the water and being able to switch seamlessly between gills and lungs.

I'm aware its a troll and you're probably jerking it to this thread but this is like explaining two plus two, no real time wasted on my behalf.

Also: "

The oceans are huge. The sky is even more so. The ocean needs less adaptations to survive in however; so has more life in it. Hunting for food when airborne is incredibly difficult. You'll probably reply with something retarded to this but hey, pretending you're an idiot is a fun pass-time for some people.

Shame you aren't pretending.

still doesn't make sense, you could easily just have really light buoyant fish

>>5612572
Now think. What's the advantage of your fish.

What does it gain by becoming a hot air balloon for extended periods of time.

And what does it need to support that function in terms of biological systems. Are they energy efficient? How much food will it require? Does it get that food once airborne?

You've described a creature that fits no niche and does something horrifically inefficient.

>> No.5612593

>>5612579
it would be light efficient semi transparent and eat insects and smaller fish

To hunt insects it would need to be quick in the air. It would also need to avoid predators like birds while airborne. That means it needs wings. Getting wings means swimming is impacted and it'll be slower in the water, making it more vulnerable to other waterborne predators.

Being "light" would mean it wouldn't hold up well in any real depth, but if its after insects it would have to be freshwater any way (no insects in the ocean).

In short, it'll either prefer to hunt in the air; eventually becoming more and more efficient so water hunting fades away, or it'll become more efficient at hunting in the water, becoming more of a fish.

The two methods of predation are fairly mutually exclusive however.

Your original assertion: "air is a fluid too" as a reason for there to be flying fish has been destroyed both through physics (water is far, far denser as a fluid) and biology (compare the anatomy of a fish and a bird; both specified for their environments, and note the differences).

The only advantage you can think of is "it can hunt insects" which doesn't seem efficient.

I've got things to go watch now, so I'm finished here. The final, most damning piece of evidence is that there, you know, isn't something that survives fully in both environments with ease. The closest you get is an amphibian, likely using a toxin to paralyze fish and a tongue/projectile to catch insects. Enjoy.

it won't be fast, but it will be able to react quickly, it's skin will also be such that insects don't even see it, same with predators
if air is much less denser than water than skish(sky fish) will have to be much less dense than fish
