Male elephant seals (bulls) rear up on their foreflippers and fight for territory and harems of females. Bull elephant seals will haul out and fight from December through March, nearly fasting the entire time as they maintain their territory and harem. They bite and tear at each other on the neck and shoulders, drawing blood and creating scars on the tough hides. Sandy beach rookery, winter, Central California, Mirounga angustirostris, Piedras Blancas, San Simeon

Courting pair of southern right whales underwater, Eubalaena australis. While the posture in this photo isn't quite mating, it is a courting behavior that often precedes mating.  The male is below, upside down and trying to access the female belly-to-belly. However, the female does not want to mate, so she has positioned herself upside down at the surface so that the males in the courting group cannot reach her genital slit, Eubalaena australis, Puerto Piramides, Chubut, Argentina

Courting group of southern right whales, aerial photo. Mating may occur as a result of this courting and social behavior.  The white whale seen here is a serious player named El Copulador (the copulator) and is often seen in mating and courting groups of southern right whales at Peninsula Valdes. His light coloration is an indication that he was a white calf, but he did not darken as he aged in the way most white southern right whale calves do, Eubalaena australis, Puerto Piramides, Chubut, Argentina

Male Brandt's Cormorant Skypointing, Courtship Display, Breeding Plumage with blue throat and a few white pin-feathers, La Jolla.
