A population of Weddell seals (Leptonychotes weddelli) at White Island on the McMurdo Ice Shelf, Antarctica, appears to be geographically isolated.
The population of Weddell seals has been estimated to … In many marine mammals there only needs to be a slight change in adult survival to influence population growth and so it is likely the hunting of Weddell seals impacted population numbers in … The National Marine Mammal Laboratory ... An international group of scientists is currently collaborating to decide a good population estimate. Weddell seals attain sexual maturity at age 3-6 years for males and 2-6 years for females, depending on availability of food, population density and other environmental factors. While Weddell seals were not commercially-hunted, they provided food for each base’s resident dog teams. The estimated population of Weddell Seals is in the region of 800,000 individuals. Weddell Seals have no subspecies Interesting Facts Weddell Seals are named after the British Antarctic explorer Sir James Weddell. Weddell Seal Breeding and Mating. Weddell seals have a circumpolar distribution and are coastal, staying around the fast ice and venturing only 15–20km into the Southern Ocean to feed. They also eat some cephalopods and crustaceans. Weddell seals are calm on shore allowing close observation : Census data currently are being compiled, and Jolly-Seber estimates of population size and other parameters will be determined. Each seal was checked for age (adult, sub adult, or pup), sex, and presence or absence of a tag. I Weddell seals haul-out onto the fast-ice to rest and moult, and for females to pup. These 1981 data are being added to the long-term population database for the Weddell seals of McMurdo Sound. ... Weddell seals are often protected from predators during the winter since both the killer whale and leopard seal cannot travel great distances under the ice. Weddell seal foreflippers are proportionately short and narrow, and owing to the short neck, originate in the forward ⅓ of the body. Weddell Seal Population Count. Weddell seals, Leptonychotes weddellii, live further south on the planet than any other mammal.Although most ice-loving seals prefer the pack ice, Weddell seals are found on near-shore fast ice.This seal’s population is estimated at 800,000 around the Antarctic continent.
Abstract. Being versatile feeders, the main food for the Weddell seal is fish, such as the Antarctic cod and Antarctic silverfish. The metabolic "cost" of diving in terms of extra oxygen consumption is about 1.5 x the resting rate - this is much lower than other diving seals and birds and makes diving more efficient. Similar Animals Leopard Seal Crabeater Seal Ross Seal Bearded Seal Hooded Seal Weddell seals are highly vocal and their underwater calls are normally quite audible to a listener on the surface of the ice.
