Ontogenetic shape trajectory of Trichomycterus areolatus varies in response to water velocity environment.

Body and head shape among fishes both vary between environments influenced by water velocity and across ontogeny. Although the shape changes associated with variation in average water velocity and ontogeny are well documented, few studies have tested for the interaction between these two variables (...
