Abstract
Hydra species differ in morphology, development, physiology, and ecology. Repeatability of experiments therefore will depend upon correct identification. I outline a procedure for distinguishing between the types of hydra used most frequently in research. Three major criteria are used: (1) presence or absence of symbiotic algae, (2) arrangement of tentacles on buds, and (3) shape of the holotrichous isorhiza nematocyst.
