Of course not.Dont forget the fish and snakes.
There are a total of 120 bones in all four limbs (30 bones in each arm and 30 bones in each leg).
No :)
For certain all higher animals do. It also depends on your meaning of limbs. But, all Chordata have a backbone. Only Vertebrate that does not have limbs, if your are defining limbs to be legs and arms, are the fish. The term use to describe 4 limbed animals is tetrapod.
Example of vertebrates (having a spinal column) could be humans, whose fore limbs are arms, as we stand upright. Then there are animals like the horse, whose fore limbs (indeed all four limbs) are actually legs.
No, animals have only two humeri (large bones in the forelimbs).
Yes, they have four legs (so they have four 'limbs').
depends, most have 4 but some like snakes actually have 2 stubs ( long gone legs) All vertebrates on Earth(life with spines, bones, etc) with limbs have four limbs with two exceptions: Sirens (a variety of salamander) and the Mexican Mole Lizard, which have only two front limbs and no hind limbs.

No, not every animal has a backbone. Only animals that belong to the phylum Chordata have backbones, while insects and mollusks do not.
The four animals that exhibit homologous limbs are humans, whales, bats, and cats. Despite their different functions—manipulation, swimming, flying, and walking—the underlying skeletal structure of their limbs is similar, reflecting a common evolutionary ancestor. This similarity highlights the concept of evolution and adaptive radiation, where species evolve distinct traits while retaining fundamental anatomical features.
Pelvic size generally correlates with the size of the animal and varies with the structure of the animal and how it uses it's limbs for locomotion. The size, structure and orientation of a bipedal animal's pelvis is allows for vertical attachments of the bones and muscles of the legs...
