Generally there are the same but in Naruto they have Clone jutsu: Shadow Clone jutsu, water Clone jutsu, wood Clone jutsu...and they have temperately form and despair after a while.
Invisibility and Cloaking are same for me too.
A Clone is a 1 to 1 copy, Naming it 'shadow' or 'water' suggests the Clones have other attributes or traits, more like elemental Duplicates, not 1 to 1 clones. Which I wouldn't put under Cloning.
Can someone with Cloning also 'duplicate' others?
