Weddell seal

3D Weddell seals' personality is rather hard to understand. Thus, With their 'smiling', whiskered faces and relatively small heads, the large 3D Weddell seals are quite appealing in appearance. However, since 3D Weddell seals use their strong teeth to chew and scrape breathing holes in the ice, extensive tooth wear occurs and is often a cause of mortality as older seals lose the ability to hunt or maintain their holes. Both male and female 3D Weddell seals vocalize noisily underwater using a variety of calls; males may do so to maintain established territories.
