scales
You might be a fish from the Placoderm group. Placoderms were an extinct fish group known for their armor-like bony plates covering their bodies, providing protection. They existed during the Paleozoic era, from around 430 to 360 million years ago.
The flap of tissue that covers a bony fish gill is the bony operculum.
Denticles are small tooth-like structures found on the skin of cartilaginous fish like sharks and rays. They differ from the bony fish's scales, which are hard, flat plates covering their bodies. Denticles help reduce drag in water and provide protection, while scales are more rigid and serve as a form of armor for bony fish.
The placoderm is actually an extinct fish, thought to have lived during the Devonian period and is thought to have had broad flat bony plates covering its body.
Most bony fishes have scaly covering on body as Labeo .

No. It's a fish and therefore a vertebrate
They are called "scales" and they overlap one another, all in the same general direction, to provide some limited protection against other fish and predators.
not all fish have skeletons on the outer skins of their body but some like the sword fish do
* im not sure but i think the answer is bony spines protruding from the body with skin covering them
