📖 Overview

Occurs in shallow rapids of rivers with bottom composed of small to medium-sized flat rocks (up to 50 cm diameter), over a substrate of coarse sand and pebbles. Observed to hide under rocks during daytime and forage on epilithon on the upper surface of the rocks at night. Diatoms (83% of total volume), as well as sponge fragments and spicules associated with fine sediments and sand grains made up the stomach contents of two specimens. Mainly herbivorous, corroborated by its long intestine reaching nearly 11 times the standard length .
