Morphometric and Reproductive Status Data for Sea Otters Collected or Captured in Alaska

This dataset includes morphometric measurements and pregnancy / dependency status from sea otters captured or collected (experimental harvests or recovered after the Exxon Valdez Oil Spill) in Alaska, 1947-2019 by the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS). Data collected include total body length, tail length, body mass, axillary girth, paw width, canine diameter and baculum length along with sex, age, and reproductive status of females (pregnancy / dependency status). For females with dependent pups, pup sex, mass, and total length are included when available. For harvested animals, data includes pregnancy status along with fetal sex, mass, and length.
