The Southern Ocean around Antarctica is home to 10 cetaceans, many of them migratory. There are very few terrestrial invertebrates on the mainland, although the species that do live there have high population densities. High densities of invertebrates also live in the ocean, with Antarctic krill forming dense and widespread swarms during the ...
The Southern Ocean, also known as the Antarctic Ocean, [1] [note 4] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [5] With a size of 21,960,000 km 2 (8,480,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
The most abundant concentrations of salps are in the Southern Ocean [4] (near Antarctica), where they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill. [5] Since 1910, while krill populations in the Southern Ocean have declined, salp populations appear to be increasing.
The southern elephant seal is believed to be the largest carnivoran of all time; bulls typically weigh 2,200 to 4,000 kilograms (4,900 to 8,800 pounds). The lobodontine seals comprise about 80% of the global biomass of pinnipeds, a reflection of the high productivity of the Southern Ocean ; all have circumpolar distributions surrounding ...
“The most dreaded bit of ocean on the globe – and rightly so,” Alfred Lansing wrote of explorer Ernest Shackleton’s 1916 voyage across it in a small lifeboat. It is, of course, the Drake ...
Type C orcas in the Ross Sea in the Southern Ocean: The eye patch slants forward.. Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested.
Antarctic krill (Euphausia superba) is a species of krill found in the Antarctic waters of the Southern Ocean.It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 animals per cubic metre. [3]
