The skin contains layers that protect the internal parts of the body. The epidermis is the outer layer of the skin that contains cells called kertinocyte that pact together so that no bacteria can pass through the deeper layer of the skin. Aside from this protective barrier, the skin also has Langerhan cells that are part of the immune system. These cells signal the immune system to release white blood cells to protect invading harmful bacteria and other forms of infection. This is the reason why every time you scratch your skin it turns red and becomes swollen.

The answer is dusk and dawn.

Crepuscular animals are active during twilight (latin crepusculum). Twilight is a period after dawn and before dusk, so crepuscular animals want to avoid dusk and dawn.

I believe it would be polyphyletic.
Polyphyletic groups are formed when two lineages convergently evolve similar character states. Organisms classified into the same polyphyletic group share phenetic homoplasies as opposed to homologies. The key difference between paraphyletic and polyphyletic groups is that paraphyletic contain their common ancestor, whereas polyphyletic groups do not.
