In zoology, a tentacle is a flexible, mobile, elongated organ present in some species of animals, most of them invertebrates. In animal anatomy, tentacles usually occur in one or more pairs. Anatomically, the tentacles of animals work mainly like muscular hydrostats.
Draenei “tentacles” are no more mobile than hair. They can not move under their own power and just droop with gravity.
Draenei do not have tendrils either. Also from Wikipedia:
In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape that is used by climbing plants for support, attachment and cellular invasion by parasitic plants, generally by twining around suitable hosts found by touch. They do not have a lamina or blade, but they can photosynthesize.
For one thing, Draenei are not plants. Even if you just want to define it as something like a plant tendril, they do not wrap about anything for stability and a much too thick to do so even if they wanted.
Draenei have neither tentacles or tendrils. They have flesh protrusions that behave exactly like hair.
They’re antenna, actually. Draenei use them to smell like any other insect. Draenei are able to move their antenna at will, but choose not to as a courtesy to other members of Azeroth. It’s gross.
If you ever see a Draenei standing there with one of these in his or her mouth… it is NOT like futzing with a lock of hair. You are seeing something very wrong. They are not being appropriate in public.
