Aggression and sexual activity of male Southern elephant seals, Mirounga leonina
The agonistic and sexual activity of individual male Southern elephant seals (Mirounga leonina) was studied during the breeding season at South Georgia. Harem bulls were older and larger than non‐harem bulls and, although size and age are related, harem bulls were also larger than non‐harem bulls of...
