Are insects considered animals?

They are part of the Animals Kingdom. They're Class Insecta

yes

insects are part of the Kingdom Animalia

yes,insects are considered animals.+5

They sure are.

Of course they are

Yes they are. Their kingdom is Anamalia, and their phylum is Arthropoda.

Yes, Insects are animals, but they are not mammals.

They're animate organisms so they are animals.

I'm not saying that this includes you, but some people think that all animals are mammals or that those words are completely synonymous.

Anything that eats and defecates is an animal, a simple game of "Animal, mineral, vegetable" will confirm that they are neither plants nor rocks, so they must be animals, unless you want to be pedantic and add fungi, even so, insects are not fungi either!

Science classification status says ..yes. I disagree. The insect species classification as to Animal should be reviewed and is being studied since it was established in the 1700s. These insects should be a third species classification undoubtedly.Vertebrae species are animal, not insects, several biological scientists are attempting to re-classify insects, not animal or plant life, exo-skeletal and arachnids are a categorized sub-species, eventually the science will prove that this outdated classification was due to lack of knowledge and for no other reason than at the time no one knew what to classify insects as.

Insects are considered animals based on the premise of Greek philospher Aristole. But common sense and scientific studies are more than enough to show insects should be classified as its own group of organisms, just like plants.

Insects are too diverse in number (an estimated 6 million to 10 million different species); have no lungs, veins and arteries for oxygen; use hemolymph instead of actual blood; are small usually with some form of exoskeleton instead on an endoskeleton; are the only invertebrates that have developed flight; undergo a series of moults; and usually have very short lifespans and can produce as many as hundreds of offspring.

If you ask me, insects should be classified as the third major form of organism life, along with plants and animals. To consider an insect like a beetle in the same animal kingdom as, say, a horse is insane.

In scientific usage, always.
In non-scientific usage, not always.

"animal (plural animals)

- In scientific usage, a multicellular organism that is usually mobile, whose cells are not encased in a rigid cell wall (distinguishing it from plants and fungi) and which derives energy solely from the consumption of other organisms (distinguishing it from plants).
A cat is an animal, not a plant.
Evolutionary biologists say humans are also animals.

- In non-scientific usage, any member of the kingdom Animalia other than a human being.

- In non-scientific usage, any land-living vertebrate (i.e. not birds, fishes, insects etc)

- (figuratively) A person who behaves wildly.
My students are animals."

Creatures yes animals no

no but spiders are because they have eight legs.

Of course they are animals.

They make great pets for the whole three days of their lifetime.

Insects are indeed categorized under Animalia by science, which only tells what science, in, around and since 1700 BC, categorized it as. Besides not being memmals there's in my vision much more odd about them. Call me crazy, but please follow me for a moment;

Looking back in time, the animals were bigger than now. It is clearly proven that a long time ago (vertibrate) creatures were big, and through time (>evolution) they evolved themselves always in an adapting way. Adaptation for survival.
Now, all animallife evolved through a long time to smaller sizes, which could be simply out of need to survive the growth of population within same space, the need to live from less food, and so on.

One could say generally that adaptation but also sophistication happens through evolution.
A one-cell organism, or algea, or a snake, or a cow, or a chimpansee all seem quite similar in matter of 'matter'. It's skintissue, plasmabody, 'blood'stream, etc. all are organisation of cells where i dare say that the human being seems the highest evolved organised system of cells.
But, the scale of functional bodyparts seem also to have a size-limit downwards.

Now let's look at insects.
There are some good close-up pictures on the net of most of them.
All functional bodyparts are not only so small yet so detailled, like miniature bodies,
but also they all look to me a bit 'hightech'..
In matters of evolution, where usually it's about getting smaller, more efficient and more developed, one could say that the insects seems like a few millions years ahead of us. Invertibrates could be also a result of evolution.

''Sure,'' i hear you think now, ''i dont think they have a brain or a personality, its just stupid bugs'' ......But than please consider the odd possibility that they dO indeed communicate, think and even have awareness, but simply don't talk like us, maybe they use even telepathy.

Ok, to now put me down as straightforward nuts, or to think i'm just another of those stoned-out conspiracy thinkers, would be a simple thing.
I find it rather arrogant and oblivious to think so easily that we are the most intelligent or most evolved stardust in the universe, or even on our planet.

Did anyone ever study if insects could live outside earths athmosphere? How fast would they fly without gravity?

Before you judge too hastily, take a good look at some of those close-up pictures,
http://izismile.com/2009/10/27/extreme_close-ups_of_insects_eyes_18_pics.html , and compare it's details and structures and mechanisms to any other living being on our planet,
and judge for yourself.
