Improved Familiar allows a templated creature as your familiar. Familiars count as their master's HD. Do celestial animals gain Elemental Resistances and DR according to the graph as if they were their master's HD?

I would have to assume so; they get skills, feats, attack bonuses, and base saves based on their hit dice.
