What is the world most USELESS animal?

Question

Dont say any insects because they are sooo useless its obvious.

Answer 1

It is very sad that you feel the need to question the utility of animals. Perhaps you regard them with so little respect that they only have meaning to you in terms of their use. If you want to ask a good question about the usefulness or uselessness of animals then try this; how useful are you?

Answer 2

Nothing is useless in this world ! Only thing is you should know what is its use. If anything is really useless, it would not have a place in this world.

Answer 3

All animals have a purpose on this planet even if we humans don't understand or like them...
Insects are one of the most important animals on this planet. There are millions spicies of them. Without them, life as we know it would not exist!
If I have to choose one, the human is one of the most useless of all I think, the arogance and ignorance of some make some think they are invincible and better than everything on this planet...

Answer 4

I have often pondered the relevence of ticks within the ecosystem (and ticks aren't insects theyre arachnids). I don't think anything feeds on them, they are vectors for disease (I guess good for the disease, not so good for the host) and itch like hell!
A sloth would actually have a relevence in providing a symbiotic relationship with the lychen and moss that grows upon its fur, as well as microfauna that utilise its faeces. Plants would rely on the sloth to spread seeds and fruits (seeds passed through in faeces, sloth travels to ground, defecates and thus seeds dispersed). Insects are HIGHLY valuable, and I would like to see what would happen in your little world without them - think of all the faeces that would accumulate, the reduced number of flowering plants reliant upon them for fertilisation, lack of traffic and crowd control models based on insect behaviour, lack of animals that directly and indirectly feed on them and you get the idea...
Just because something does not appear to directly benefit us does not mean it is a completely useless species! Humans are so ignorant hence why we have f@#$ed our planet so much!!

Answer 5

Insects are VERY useful actually. Have you seen Life in the Undergrowth with David Attenborough??

Answer 6

In what sense?
I don't think any animal is useless.
I noticed some people saying the sloth, but being
slow does not equate to lack of worth.
Some people have mentioned animals they hate,
which isn't accurate.
Insects feed larger animals, like birds,
which in turn feed yet larger animals, so have their
place.
All animals have their place in the world.
Yes even people.
We evolved to where we are, and we are animals.
But even still, people think of homo sapiens as
being outside of nature. Which just isn't true.
Even humans have their place.

Just because you don't like an animal or what it does, does
not make it useless. But people can often only think of
things in terms that relate to them.

Someday our species will die and another will take it's place.
And during this process the world will heal itself, and change
continuously, until one day the sun turns the Earth to
ash or something of that nature. We are all just a small
speck on a constantly changing world, and you are
measuring significance by what means?
Essentially all species die, and are ultimately replaced by
a mutated cousin, or what have you. The earth is
hundreds of billions of years old, the universe is
supposedly eternal. So how do YOU measure worth?
By whatever suits your needs? Or do you have a larger
grasp of what is significant? Something beyond you?
Something greater than you?
Use and worth can only be measured by perception.

Answer 7

No animal is useless, not even insects

Answer 8

Insects are not useless. I don't believe there is any useless animal. They all have their purpose, and place on the planet.

Answer 9

Your question is seriously ill posed. It shows a complete lack of understanding of evolution by natural selection and basic genetics. There are no useless animals; the question does not even make sense, from a biological perspective. The purpose of all animals, plants, protists, fungi, etc., is to replicate the immortal genes within themselves; at the most basic sense of purpose.

Answer 10

Nothing is useless. Insects feed things and dispose of dead things. Jellyfish feed sea turtles. Rats feed birds of prey and small carnivores, and even when speading disease they are strengthening the overall population of whatever they give the disease to in the long run, because the ones who are strong enough to survive the disease live on and have kids that would survive the disease too.

I know it has a purpose (and something else would just fill it's nitch if they all died), but i absolutely hate ticks. I suppose they are good at spreading lyme disease though...
