Figure 6.Ventral views of palates of a Monachus monachus b Neomonachus schauinslandi, and c Neomonachus tropicalis. The tooth row of Monachus is more crowded, likely as a result of the shorter rostrum, and this results in a more obliquely oriented set of post-canine teeth and the lack of a diastema between the upper canine and the first premolar. In Neomonachus, there is a distinct diastema between C1 and P1, and the post-canine teeth are arranged more linearly. The upper incisor arcade of Monachus is slightly parabolic due to the posterior placement of the lateral incisors, and the anterior premaxilla appears slightly curved. In Neomonachus, the incisor arcade is linear and the anterior premaxilla is straight.
Crabeater Seal (Lobodon carcinophaga) / Morning navigation to Booth Island's Salptrire Bay, a 3 km (1.9 mi) wide bay indenting the north shore of Booth Island, in the Wilhelm Archipelago. It was charted by the third French Antarctic expedition (190305) under the command of Jean-Baptiste Charcot. Charcot established the expedition's winter base at Port Charcot in 1904. A cairn at Port Charcot, with a wooden pillar and a plaque inscribed with the names of the members of the French expedition, has been designated a Historic Site or Monument, by a Antarctic Treaty Consultative Meeting. In the late morning, due to excessive ice, we took a zodiac cruise of Salptrire Bay (650356S 640108W) along the west side of Booth Island and waited for better conditions in the afternoon to make a landing at Port Charcot.
Attribution: Latitia Kernalguen. A harem of 127 females is a prize that has to be earned. Where female Southern Elephant Seals (Mirounga leonina) provide all the parental care, they will only reproduce in the territory of the biggest males, the biggest fathers for their offspring. Females average 400 to 900kg, while males weigh up to 4 tons; Southern Elephant Seals show the largest sexual dimorphism among land breeding mammals. When a male challenges the head of a harem he needs to prove his strength at a great cost, resulting in a fascinating and captivating fight between the two giants.Winner: Behavioural and Physiological Ecology.BMC Ecology 2013, 13:6 doi:10.1186/1472-6785-13-6www.biomedcentral.com/1472-6785/13/6

Figure 7.Dorsal view of rostra of a Monachus monachus b Neomonachus schauinslandi, and c Neomonachus tropicalis. Monachus exhibits a well-developed antorbital process on the maxilla, immediately inferior to the fronto-maxillary suture. The process is reduced or absent in Neomonachus. The nasals of Monachus are short and triangular, tapering smoothly posteriorly to produce a point at their union. The nasals of Neomonachus are longer and do not taper smoothly.
