These numbers are not accurate, as accurate number of animal species on earth has yet to be discovered. Currently it looks like less than 3% of the known species of animals on earth are vertebrates (have back bones). There are around 50 000 species of vertebrates, most of which are fish. Most animals are invertebrates, and most of those are insects.
Insects alone make up well over half of all species in the world. I'd say about 60-90% don't have a backbone. Hard to answer, really, because we've only discovered about 10% of all species on the planet. Chuis
About 95% of all animal species on Earth do not possess a backbone.
They are called invertabrates. Animals that dont have a backbone.
I was under the impression that they dont. They are very independent creatures
The Holy Quran and the Holy Bible say that the first creature was Human. Leonardo Darvin had an evolutionary theory which has no base and now its not accepted by the science itself
well there is a lot perhaps too many to list but most bugs have no backbone except the butterfly (exo skeleton) and the octopus does not i know slugs do not
Dont quote me on this but a daddy long leg spider.
no i dont no
They are called invertabrates. Animals that dont have a backbone.
i dont no what is the answer
they dont have backbones.
if we dont have any backbone we can not stand properly or we cant even stand
i dont know the percentage but it covers about 1 third of the earth.
Butterflies are invertebrates and do not have backbones.
No, they do not have a backbone, they have an exoskeleton.
umm...............i dont know
i dont think the butterfly have backbone because of the wings if they have backbones they cant fly.
Yes, mosquitoes are invertebrates as they have no backbone.
vertebrates have a backbone and stand up for what they believe in and inverebrates dont have a backbone and cave in when challenged
