Lab animal
A lab animal was any specimen, typically an animal, used for scientific testing in a laboratory setting. The term lab rat or laboratory rodent was often used to describe humanoids who were being exploited as test subjects for scientific research against their will. (, , )

One such test given to these creatures was a behavioral test. ()

Sometimes the animal was already dead when used for testing. In 2259 of the alternate reality, Doctor  injected a sample of 's Augment platelets into a dead tribble. Later, while despairing over 's death, the tribble came back to life, prompting McCoy to give Kirk the same treatment, which ultimately led to the captain being revived. ()

Some lab animals were more sensitive than others. In 2269, James T. Kirk inquired on the status of 's sickbay's sensitive lab animals. ()
