Man are you way behind, that picture of acnologia is from a long time ago.

From the fairy tail wikia on dragons-

Magic and Abilities- Dragons are extremely powerful creatures, so powerful, in fact, that a form of Magic had to be created to combat them; their scales are so strong that, aside from Dragon Slayer Magic,[11] no other form of Magic can pierce through them.[12] This conceived notion does not, however, apply to Acnologia, who was unaffected by both regular and Dragon Slayer Magic.[13] Dragons can also be wounded by their fellow Dragons.[14]

In several of the scenes in the show and manga you see that the scales are layered on top of each other, this is shown during the grand magic games with the 7 dragons, and the few times there have been close ups of acnologia.

Acnologia's arm is almost completely regenerated the second time he appears during the war in his dragon form.
