Southern Elephant Seal v Southern Bottlenose Whale
#1
Southern Elephant Seal - Mirounga leonina
The Southern Elephant Seal (Mirounga leonina) is one of the two extant species of elephant seal. It is both the largest pinniped and member of the order Carnivora living today. The seal gets its name from its great size and the large proboscis of the adult males, which is used to make extraordinarily loud roaring noises, especially during the mating season. The Southern Elephant Seal is distinguished from the Northern Elephant Seal (which doesn't overlap in range with this species) by its greater body mass and a wider proboscis. This seals' size shows extreme sexual dimorphism, possibly the largest of any mammal, with the males typically five to six times heavier than the females. While the females average 400 to 900 kilograms (880 to 2,000 lb) and 2.6 to 3 meters (8.5 to 9.8 ft) long, the bulls average 2,200 to 4,000 kilograms (4,900 to 8,800 lb) and 4.5 to 5.8 meters (15 to 19 ft) long. The record-sized bull, shot in Possession Bay, South Georgia on February 28, 1913, measured 6.85 meters (22.5 ft) long and was estimated to weigh 5,000 kilograms (11,000 lb). The maximum size of a female is 1,000 kilograms (2,200 lb) and 3.7 meters (12 ft). When at the subantarctic or Antarctic coasts, the seals can also consume shellfish, nothothens, lanternfish, krill, cephalopods or even algae.

Southern Bottlenose Whale - Hyperoodon planifrons
The southern bottlenose whale (Hyperoodon planifrons) is a species of whale, in the ziphiid family, one of two members of the genus Hyperoodon. Seldom observed and rarely hunted, the southern bottlenose whale is resident in Antarctic waters. The species was first described by English zoologist William Henry Flower in 1882, based on a water-worn skull from Lewis Island, in the Dampier Archipelago, Western Australia. Southern Bottlenose Whales are relatively large beaked whales, reaching a maximum of 7.14 m and 7.8 m for males and females respectively, and maximum weight of about four tonnes (Ross 2006). Their body shape is robust and they have a large, bulbous-shaped forehead and a short, dolphin-like beak. The rear half of the mouth-line curves upward and there is a pair of grooves on the throat, typical of beaked whales (Martin 1990). Southern Bottlenose Whales have a falcate (sickle-shaped) dorsal fin that is set well behind the middle of the back. The colour of Southern Bottlenose Whales is chocolate brown to yellow, being lighter on the flanks and belly. This coloration is believed to be caused by a thin layer of phytoplankton diatoms living on the whales' skin (Culik 2003). Mature males have a squared-off forehead, whereas in females and immature males it is rounded. Males possess a single pair of conical teeth at the tip of the lower jaw, rarely visible in live animals (Gowans 1999). The broad tail flukes are un-notched and deeply concave, while the flippers are small and tapered (Shirihai 2002).

Both animals live and swim in the ocean surrounding the antartic and they are very likely to meet. The cetacean is slightly lighter than the elephent seal and both do not really have the weapons to seriously injure each other. The southern bottlenose whale can ram the elephant seal and would likely dominate in the ocean.
