Actions
Bite. Melee Weapon Attack: +5 to hit, reach 15 ft., one target. Hit: 8 (1d12+1) piercing damage, and the target must make a DC 15 Constitution saving throw, taking 13 (2d10 + 2) poison damage on a failed save, or half as much damage on a successful one.

writing out the details of "acid immunity" is redundant this is all covered by the resistances an immunities section.
since it's an acid snake why doesn't it's bite do acid damage?
