📖 Overview

Cave-restricted species . Collected in a pool of moving water about 1 km from a cave entrance . Mostly found stationary on the muddy bottom at depths from 20 cm to 1 m . Tends to occur in slow moving water during the dry season, but some individuals were observed climbing rapids . Small groups of individuals were frequently found in the pools while isolated individuals were common in rapids . Weakly or not at all cryptobiotic, not remaining under rocks for more than 5 min during the day . Feeds on insects and roundworms . Shows behavioral responses to light, including avoidance and perhaps a residual diurnal rhythmicity .
