Physical and Imagery-Based Morphological Measures of Pacific Walruses in Human Care

This dataset contains morphological measures of 21 Pacific walruses in human care in the United States, Belgium, and Germany measured directly and via an aerially mounted camera in 2022 and 2023. Six individuals were measured twice: once at their typical annual lowest body mass and once at their typical annual maximum body mass. The remaining 15 individuals were measured on one occasion. Straight-line linear measures of width behind the front flippers and at the hip, full girth behind the front flippers, straight line length, snout width, and body mass were collected as direct, physical measures. Straight line body length, width behind the front flippers, width at the hip, and body area footprint were measured from aerial imagery.
