Even the most useless animal serves a purpose, say if one animal died out, it would really fuck up the food chain.
Tell me one purpose of the Chiwawa (spelling? you know that stupid dog thats only used to portray mexican stereotypes in bad movies)

(Cat owners, don't bother responding; you'll simply be proving my point.)
The common forum troll; the only truly useless species in internet ecology, or backbone of the online food chain? Discuss.
I would say useless but sadly we have no data, if only we had one in captivity to study...

Define useless. Biologically, an animals purpose is to propagate itself. If it's still around, it has been useful for that. Are you talking about only creatures that serve a symbiotic purpose with another creature? Well in that case, the vast majority of major predators, since all any one predator does is muscle in on the resources of another. Basically, before you call something useless, what use do you speak of?

lol do humans even have a use? are we changing the universe towards something that would benefit the universe?

seriously, useful is only a term meaning useful to us.....the actual idea of life being useful is preposterous, if the earth blew up today, and every single organism died, would the universe care?


long story short, i dont think anything really matters

its what lead me to nihilism, i could be the greatest person ever, but it really doesnt matter...


but thats also an inspiration to me, i can do whatever i like

Mosquitos. Anything that can eat a mosquito can eat any other insect and they just bother us humans.
Mosquitoes put the proteins humans develop back into the food chain by being consumed by frogs and fish. If you really want to give back to the biosphere, go for a nice hike and let the mosquitoes feast. Also, the mosquito's bite is anesthetized, so animals don't feel it, it just so happens most humans are allergic to the anesthesia. So it's our fault we get all itchy, not theirs. They're just trying to numb the sting. What would you rather have, an itchy bump or a sting? I still hate 'em.

Platypus aren't useless, that ridiculous bill lets them get at worms n such in the mud others animals can't find, they also have a highly developed electric sensory field to detect movement through a few inches of silt.

Koalas are pretty useless, but if they can survive in the poisonous hellhole of Australia, I think they deserve a vacation.

EDIT: Pandas are pulling a nice con on humanity, they're like the welfare cheats of the animal kingdom. I don't see them when I go to the zoo, and they're really just asshole animals. Some animals are friendly with their keepers, but not pandas.

i'd say that snails seem rather useless on the whole
at least I never see any real purpose to their existence
Food for birds, hedgehogs, raccoons, badgers, and many others, things are so bad back home that hedgehogs rely on my parents putting out cat food scraps.

i heard about a scientific study that prooved mosqitoes were the only living thing that wasn't the main part of the diet of any other organism. Basically the mosqitoe could be completely eradiacted and while there would be an imballance in the food chain it would recover. On ther other hand mosqitoes do help to controll the human population ie. by spreading deases and making the outside less appealing therefor promoting obesety.

Fun fact: The femal mosqitoe is the blood sucking monster whilst the male mosqitoe's only purpose is to reproduce...
First your statement that they are not the main part of any diet is false, instead of blindly believing things, look it up for yourself...

"The dragonfly nymph eats mosquitoes at all stages of development and is quite effective in controlling populations."

I never said it was true and besides my argument was that nothing eats mosqitoes as their main diet. I don't feel like reading the wiki page so i don't know if that contradicts me but then again its wiki, ie. that site editted by anyone with a computer.

You know I had a big reply earlier in this thread about how parasites actually vastly influence the evolutionary process, how they help control populations and how they are perfectly evolved to do what they do and possess more sophisticated systems them we can even imagine.

What is up with this irrational hate of parasites? Seriously, they're just as important as insects are.
Well Botflys and tapeworms for an example doesn't kill their victim, they are just there to casue suffering. A botfly, when it hatches, finds a mate and reproduce and then the female botfly lay more eggs. Thats it's whole life if what I've read is correct. Tapeworms just hangs on in your gut and eats what you eats. As they do't kill anything they don't really help in getting rid of the weak

The sloth and koala.
Seriously, if eating and sleeping are productive to any purpose then my teenage years were some of the most productive mankind has ever seen.

I beg to differ. For example, there is a type of tapeworm who's final host is a wolf. This tape worm's intermediate host is a moose, in which it forms cysts in the moose's lungs which make it difficult for the moose to run. As such it's more likely to be eaten by the wolves. This helps to balance predator prey to the point that, without this worm, both species would breed so out of control that they'd destroy their own environment.

As per botfly their maggots are used as a primary food source by people in cold climates and have been for thousands of years. We are directly connected to that food chain.

Chihuahuas are merely mutated rats with no purpose, so I would go with them. Unless you count them being slower and being eaten to give other animals escape time a use.
that's what i tell everyone but nobody believes me.
Mosquitoes are pretty useless and annoying

Are humans useful? All we appear to be doing is polluting the world and slowly destroying it.

but like a wasp, i don't see a reason for them to live...
Wasps are the planets natural immune system. In fact they are probably the most useful organism on the planet. Caterpillars can utterly decimate vegetation, that stuff that most of the world eats, that converts sunlight into biological energy, that gives us oxygen to breathe. Whenever caterpillars get too numerous, along comes a bunch of wasps to deal with the pesky caterpillars by stinging them, then laying their eggs inside them. Before long, the eggs hatch inside the still living caterpillars, and the wasp larvae eat the caterpillars from the inside out, just like those things from aliens.

Nature is awesome.

Mosquitoes are utterly vital for the survival of so many organisms in the world it is amazing how we ever got along with them... oh wait.. we didn't!

Mammal blood is one of the most nutritious liquids there is. When mammals eat all the useful stuff winds up in the blood after being processed. Mosquitoes come and feast on this, which we don't like. On the other hand, a whole bunch of other animals which need decent nutrition (such as salmon, bigger spiders, birds etc) chow down on the humble mosquito because it contains all of this lovely, vitamin and protein-rich mammal blood.

Mosquitoes are the worlds very first socialists.

Really now, are you really that stupid.. first off, not every one can edit this page, create an account for wikipiedia and try to edit it, I dare you. Second, why would some one falsify THAT kind of wiki. Think things through more logically next time, and yes, this does still mean your wrong, even if you don't want to admit that the mosquito hawks main source of food are mosquitoes *hinted in the name obviously....* and dragonfly nymphs main source of food are mosquitoes as well, you defended nothing when you said

"my argument was that nothing eats mosqitoes as their main diet."

I don't understand irrational wiki hate, seriously, stop being a fat lazy slob if you want to see if the wiki is true and look at the sources, or come up with contradicting ones... then check if YOU your self can edit it...

Every animal has its purpose within its own system. However, some are certainly useless to me, specifically- if every organism living around ahydrothermal vent died out, I wouldn't know, and I wouldn't care because it has zero effect on me.

(Actually, it would, because I love hydrothermal vents, but it wouldn't throw my ecosystem out of balance.)

We're so far along the evolutionary process that all animals have a 'use' if by that you mean their existence is either directly or indirectly beneficial to another species. It would be quite an achievement for a species to disentangle itself and become 'useless', though paraddoxicaly, this species would be the epitome of a well evolved species as it could not be adversly affected by other species, or be forced to be reliant upon them.
