Immunocytic gel worm

The immunocytic gel worm was a corkscrew-shaped organism that lived in a viscous pink fluid. Doctor Phlox kept a jar full of them in his sickbay on Enterprise for medical purposes.

Although Phlox allowed Captain Jonathan Archer, commanding officer of Enterprise, to observe the worms, Phlox told him not to shake them.
