Description: Small to medium sized, permanent forest streams with heterogeneous morphology and rich in submerged woods and root packs are usually inhabited by the highest numbers of Ancyronyx species. This picture shows the type locality of Ancyronyx montanus where also Ancyronyx minerva, Ancyronyx patrolus, Ancyronyx pseudopatrolus and Ancyronyx punkti occurred sympatrically. Date: 2011.
