Skulls are hidden objects in each campaign level (or now in the new multiplayer levels , I think) When you pick up a skull you "unlock" it, in the sense that you can now use it's ability in campaign. When you activate the skulls they actually have a negetive effect on you, and make the game even harder. The reason why people would do this is because it adds a bonus when you are playing to get a score ( You get an achievement when you get a certain score).

Also, if you find all thirteen skulls, you can unlock the Hayabusa armor.

Or maybe you mean, "Which are the skulls in Halo 3?". Well, here's a list.

Iron

Black Eye

Tough Luck

Catch

Fog

Famine

Thunderstorm

Tilt

Mythic

Blind

Grunt Birthday Party

Cowbell
