Jointed limbs are an important development because they allow animals, including humans, to move. Without joints we would be comprised of an immobile skeleton.

It depends on the type of animal, mammals and some types of fish will swim and sea bed animal will walk alone the sea bed e.c.g crabs, moluscs.
Brachial (as in brachial artery) refers to the upper limbs, the arms.

synovial
They can be called limbs, appendages, extremities, or members.
Diarthroses joints are movable joints. More movement is required in the limbs of the appendicular. Synarthroses joints are immovable joints and amphiarthroses are semimovable joints. Less movement is required in hte axial skeleton than in the appendicular skeleton.
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.
no sea creatures have limbs and the other animals and humans have legs

bones build on to the end of ur limbs for physical protection of your highly delicate finger ends
No,they can't.
An "extremity" refers to your limbs (arms and legs). Lower extremities are your legs; upper extremities are your arms.
Prosthetic limbs have not just helped people but they are very helpful for animals too. Animals without limbs have a hard time moving around, they actually have it worse then people because without one limb they can basically not move at all. Most animals will die if they do not have a limb because they can not hunt for food or if they are prey they can not get away. Prosthetic limbs help animals to do this stuff so they are not immobile or constantly dysfunctional
