No significant differences were detected among repeated fin measurements, which validates the accuracy (intact v. dissected) and precision (repeatability over several days) of fin AR measurements on live fishes. One exception highlighted issues that may arise when working with species prone to fin damage.Keywords: animal; article; biometry; coral reef; fin (organ); fish; histology; methodology; Animal Fins; Animals; Biometry; Coral Reefs; Fishes; Anthozoa; Pisces Labriform; Morphology; Repeated measurements; Swimming201110.1111/j.1095-8649.2011.03070.x2016-02-24
