Justification of Red List category
This species has been classified as Endangered owing to very rapid population decreases over the last three generations (30 years) combined with a limited distributional range and increasing land and sea-based threats. Precise reasons for the declines are poorly understood, but changes in the marine environment, including increasing sea temperatures and reduction or displacement of prey, diseases, and oil pollution are among the suspected causes.
