Without motion or movement; relating to the non-motile stage or characteristic of organisms lacking cilia or ability to move.
From Greek 'a-' (without) plus 'kinetos' (motion) plus '-ic' (characterized by). This general term describes any organism or life stage lacking the ability to self-propel.
Acinetics in biology represent organisms that abandoned movement—a paradox, since their ancestor ciliates were all about motion, showing how evolution sometimes turns down the energy demands of being active!
