The
pack ice
. Thus, though they are collectively the most abundant group of seals in the world, the combination of remote range and inaccessible habitat make them among the least well studied of the world's seals.
Adaptations
The Lobondontini are thought to have diverged from the
penguins, while still retaining the ability to filter-feed on krill.[4]
Abundance
The lobodontin seals in aggregate are among the most successful of all marine mammal groups, collectively accounting for at least 50% of all seals on Earth and about 80% of the global
baleen whales in the Antarctic due to commercial whaling in the 19th and 20th centuries, and the subsequent increase in krill densities.[7] Genetic evidence suggests that Weddell and crabeater seal populations may have increased in size during the Pleistocene.[8]
None of the four species is currently thought to be declining in numbers.
