ABSTRACT
Geometric morphometrics is a powerful tool for studying fish body shape; however, body posture can be a hindrance to these analyses. Here I introduce new R language tools for correcting multiple types of bending of 3D data based on the TPS suite (geometric morphometric software) "unbend specimens" methodology. In a sample dataset of darters, these R tools adequately accounted for posture artifacts otherwise evident across multiple principal component axes. I hope these new tools will facilitate the incorporation of 3D landmark data into the comparative analysis of fish body shape.
