Abstract	The California Blackworm ("Lumbriculus variegatus") is a freshwater segmented worm species that has been used by biology instructors as a model system for inquiry-based student investigations. The blackworm dorsal blood vessel pulsation rate is easily quantified. Moreover, this species can facilitate the study of neuromuscular functioning via its photosensitive escape behavior which can be quantified as a segmental reflex rate. Both of these variables can be used to examine the physiological response of the "L. variegatus" circulatory and neuromuscular systems to environmental changes. Because knowledge about this species and its optimal environmental conditions is limited, we studied dorsal vessel pulsation and segmental reflexes of "L. variegatus" maintained at differing lighting, temperature and water cleaning frequency conditions. Our data strongly indicate that "L. variegatus" circulatory and motor functions are significantly affected by environmental conditions. We provide evidence-based recommendations for the careful control of environmental conditions that will allow instructors, students and researchers to collect robust data on "L. variegatus" and better utilize this model organism in their investigations.
