FISHMORPH

This dataset offers the most comprehensive freshwater fish morphology database existing to date currently encompassing 9534 freshwater fish species out of the ca. 13 000 described strictly freshwater fish species, covering 73% of the documented world freshwater fish fauna.  Each species is described with ten functional traits, among which body size is estimated as the maximum body length registered on Fishbase (www.fishbase.org). The remaining nine traits describe the shape and position of the external anatomical characteristics of fishes (i.e. head, eyes, mouth, pectoral and caudal fins) that affect their feeding and locomotion. These traits were computed as unit-less ratios between morphological measures on side view pictures, using one or more specimens by species.
