animate
They are called sporozoa.
The protozoa that are not capable of independent movement are called "sporozoans." They are parasitic organisms that rely on a host to move from one place to another.
Maturity, I suppose.
a migration
Animals capable of moving independently of ocean currents by swimming or using other means of propulsion are called "nekton." This group includes various species of fish, marine mammals, and cephalopods, which can actively swim against currents. Nekton contrasts with plankton, which are carried along by water movement and cannot swim against currents.
soaring
Ameboid movement
It's either called stalking or hunting or tracking.
spirochetes
Because plants are rooted to the ground (although vines make their way around pretty well!).
spirochetes
Bacteria capable of movement include species such as Escherichia coli, Pseudomonas aeruginosa, and Salmonella enterica. These bacteria can move using flagella, pili, or by a process called gliding motility. Movement allows bacteria to effectively navigate their environment and locate nutrients or avoid harmful conditions.
