Even though I haven't verified it at all, it seems likely to me that 15% of max HP is the required damage for max loot on all Serpents (in the same way that I think 20% of max HP is the required damage for max loot on Dragons).

That would be:
 * 225k damage for Emerald Sea Serpent
 * 450k damage for Sapphire Sea Serpent
 * 900k damage for Amethyst Sea Serpent
 * 1.35m damage for Ancient Sea Serpent

And it also seems likely to me as that for all of them as well, this damage would guarantee 2 Epic drops, with a small chance of getting a 3rd one.
