Abstract

Foraging behaviour was studied in five specimens of the eyeless, cord-like eel Monopterus digressus</i> collected from wells charged from subterranean streams, situated at the western periphery of the Western Ghats in Kerala, India. Feeding experiments were conducted using two types of live prey, and indicated the absence of visually oriented predatory movement. Dependence on olfactory as well as tactile stimuli for foraging in the absence of visual cues was evidenced.
