生物学特性     字汇 (例如 epibenthic)

Individuals of this species were found in groups; during the day they were commonly encountered below undercut river banks, especially in dense networks of tree roots or reed beds along the stream margins; places with shallow water and slow-flowing reaches of rivers and streams are especially attractive to them (Ref. 95448). Large numbers of small juveniles were found in bushes of aquatic reeds and floating grass on the periphery of the river or in side channels (Ref. 95448).
