Growth of female southern elephant seals Mirounga leonina at Macquarie Island
Body growth of 137 female southern elephant seals (Mirounga leonina) over 1 year of age was investigated at subantarctic Macquarie Island. An asymptotic straight line, snout-tail body length of 2.570.03 m was estimated to be attained at 9years of age, using a three-parameter Gompertz equation. A sig...
