How long do flies live under water?
They're small and don't require much oxygen. So, basically, as soon as its oxygen supply runs out, it dies. Some insects have a coating on their exoskeleton that repels water, and thus forms a little bubble around them which buys them time if they fall in the water. This just may be the case with the fly. Also, please don't kill it... :/
Do U.S. Marines have to be able to breathe under water for a long time?
well its was on a video for recon marines so you answered your own question. one of my best friends is at marine boot camp at the moment and he could swim just about as good as a rock when he left. at boot camp you have to swim the full length of a pool with your gear, but you pack and vest float to keep you from going under. but when people jump in they struggle because they think they are sinking, but the floating gear makes it so barely you head stays out of the water. if you do go to marine bootcamp just remember at the pool to stay calm when you get in the water, the drill instructors are not gonna let you drown
Would you rather A) fly or B) breathe underwater??
I'd rather fly, and hey being able to fly could help you get out of water.
How long can a fly hold it's breath?
A fly can't hold its breath at all It doesn't have lungs and can't control the entry and exit of air into its body, which happens by way of a series of holes (called 'spiracles') on the sides of its body leading to a series of branching tubes taking air into its body. Gaseous exchange takes place by diffusion alone (although some insects can contract and relax their muscles to force air in and out) If you place an insect under water, air often gets trapped around its body due the nature of its 'skin' (actually called its exoskeleton) and the surface tension of the water - and air also remains in the tubes. It will take a considerable time for this air to be used up (maybe 5+ minutes). If you add something like washing detergent to the water, this will break the surface tension of the water so that there will be little or no air trapped around the fly's body. This would give a much more accurate indication of how long it can survive without air.
Is there animal that can fly, swim, breath in the water and run on ground?
There are several insects, including diving beetles, water boatmen, giant water bugs, and others that are capable of swimming and flying. They can move about to some extent on land - although most of them aren't very good at it (their legs are generally modified to make them better swimmers, and not for walking or running). These insects also don't breathe water directly. They breathe air, but many of them actually bring bubbles of air underwater with them to use something like a scuba tank. At their size, there is also some gas exchange between the bubble and the dissolved oxygen in the water - allowing them to stay down for considerable periods of time. These and other insects (including dragonflies, damselflies, mayflies, stoneflies, and many types of true flies like chironomid midges, and mosquitoes) that swim and breathe water as larvae, and then fly and breathe air as adults. There aren't any vertebrates that are capable of all of these feats, however. The so-called flying fish are capable of short, gliding flight out of water - but they don't really fly, don't breathe air, and can't move around on land. There are also amphibians that breathe to some extent underwater, move in the water and on land, and there are a few species of frog that are able to glide - using huge webbed feet to parachute when they jump from trees. That's about as close as any critter gets.
Would you rather be able to fly or breathe underwater?
Oh man, you really are making it hard to pick.See, that depends a lot on the flight mechanism, and how bodily pressure limits would be effected by water breathing. The other thing is water is extremely cold, so would I be thermally protected as well?Similarly, if it’s flying for the sake of flying like superman, then the only limit for me is that I can’t pass 25,000 feet in altitude.But if I have wings on my arms, well, then I need to contend with tiring out.So here’s the run down. Water breathing versus winged flight: tieWater breathing with thermal protection versus winged flight: Water breathingWater breathing versus unrestricted flight: FlightWater breathing with thermal protection versus unrestricted flight: Impossible to call.
Is there an insect that can breathe underwater?
Yes there are particularly aquatic larvae with modified gas-exchange body parts acting like gills. Most classical examples are water nymphs (often called nayads) of dragonflies and damselflies. Some larger ones (for instance of the family Gomphidae) are strong breathers which will "inhale" water into a modification of the anal region with such pressure that they can use the squirt to propel themselves underwater. Some very common mosquito larvae of the large family chironomidae can diffuse oxygen through their thin tegument, and will carry red hemoglobin as a diffusion pigment. Hemoglobin is also found in some aquatic swimming hemipteran (I think Notodontidae) which caused some people into believing they suck blood.
Would you rather be able to breathe underwater or fly? Why? Assume you can clearly see and be comfortable in either situation.
As long as i was able to combat the cold, under water without a doubt. Being able to fly would be a fantastic feeling, and you will be able to go where ever you like around the world.Can you imagine being able to go where no other human has been before, the deepest parts of the ocean. Being able to see never seen before aquatic species, Lost ships, planes, MH370, lost ancent cities and towns, pirate treasures.
Would You Rather Be Able To Breathe Underwater Or Have The Agility Of A Cat?
Breathing underwater definitely, on the basis I can still breathe on land and that you are breathing underwater without equipment.The ability to lick your own bits has a certain appeal but apart from that if you were into parkour you might be a good way towards cat-like ability. It just seems more attainable than breathing underwater.
