We explored predator-prey interactions between marbled swamp juvenile eels Synbranchus marmoratus; predator and anuran tadpoles Hypsiboas pulchellus; prey in relation to two aspects: the importance of lateral line in the predator and whether the absence of light modifies predation rates; and the effect of a im;ortant concentration of fenitrothion on both predator and prey.
