Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.
