Length-mass relationship for narwhals from West and East Greenland with regression line for both sexes combined. The whales from West Greenland are from [11] and those from East Greenland are from this study. The power functions that predict the mass of narwhals (East and West Greenland combined) instrumented with stomach temperature sensors were: Female: Body mass = 0.003 × Length^2.08, r² = 0.88. Male: Body mass = 0.002 × Length^2.17, r² = 0.80.
