Coral reef fishes which forage in the water column
© Biologischen Anstalt Helgoland 1973
1. Radiation of fishes representing many families in the tropical coral reef has repeatedly produced convergence in the specialization for “water-column foragers”.
2. This life mode is depicted by a recognizable set of morphological and behavioral characteristics. Exploitation of this niche has parallel examples in fresh water, and non-tropical habitats.
3. The distinguishing traits of this specialization, and the systematic, ecological and evolutionary features are described and discussed.
