The ability to detect and locate prey solely on the basis of emitted bioeletric fields was tested in the stingray Dasyatis sabina. Two species of invertebrates common in the natural habitat of D. sabina were encased in electrically transparent agar chambers and buried in sand in an experimental pool. The responses of this stingray were observed and recorded. Goodness of fit analysis of these data indicate that D. sabina is elelctroreceptive. However, there was no evidence to suggest that the stingray was able to discriminate between the two types of animals by the use of its electrosensory system alone.
