"Krill ""deposits"" transport atmospheric carbon to the ocean depths" Collectively, krill make up the single largest concentration of biomass in the oceans. At any one time, there are 400 million tonnes of them swimming about in every ocean of the world. Their place in the ecosystem is as the second tier in the food pyramid.

Krill Simply put, many oceanic life forms depend on krill. Importance to the Antarctic Ecosystem Pink and opaque, Antarctic krill (Euphausia superba) are among the largest of the 85 known krill species. Their estimated numbers range from 125 million tons to 6 billion tons in the waters around Antarctica. During certain times of year, krill congregate in swarms so dense and widespread that they can be seen from space.

Antarctic Krill - Euphausia superba Fortunately for the krill and the Antarctic ecosystem , krill go off very quickly after being caught, the Antarctic is a long way away and consumer interest remains fairly low (krill aren't very nice for people to eat). Krill is harvested by the Norwegians with smaller amounts by Japan, Russia and other nations.

- Plenty More Krill in the Ocean Krill is one of the most abundant biomasses on the planet. It is a food source for whales, penguins, seals and birds that repopulates itself each spring during spawning season.

How Many Species Are There on Earth and in the Ocean? Our current estimate of ∼8.7 million species narrows the range of 3 to 100 million species suggested by taxonomic experts [1] and it suggests that after 250 years of taxonomic classification only a small fraction of species on Earth (∼14%) and in the ocean (∼9%) have been indexed in a central database (Table 2).

Krill Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans.The name krill comes from the Norwegian word krill, meaning young fry of fish, which is also often attributed to other species of fish.f this, over half is eaten by whales, seals, penguins, squid and fish each year, and is replaced by growth and reproduction. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day.

Do I Know This ? Whales that eat krill include baleen whales like the blue and gray  whales. The blue whale, which is one of the largest whales, can eat  up to 8,000 pounds of krill in a day…. This is approximately 40  million krill in one day.

HOW MANY SEAS ARE THERE IN THE WORLD? They are smaller than oceans and typically located where the land and ocean meet. 1  It is often said that sailors sail the seven seas of the world, but is this an accurate representation of the amount of seas on the Earth? There are in fact 108 seas (including the five oceans) on the planet. They vary immensely in size and have different characteristics. The Dead Sea borders Israel and Jordan. It is famous for its scrolls and high salt content, which is six times higher than the ocean.

How Many Oceans Are There on Earth? Although the ocean is one enormous and interconnected body of water, it is broken up into four regions. The four ocean regions are the Atlantic, Pacific, Indian and Arctic. These oceans cover 71 percent of Earth's surface and are interconnected by a series of currents that carry water in continuous cycles throughout all of the oceans. Throughout history, their boundaries have changed and, as of 2000, some countries have recognized and named a fifth ocean.

- Squid and small fish. Squid and small fish as well as whales feed directly on krill. Of the estimated 100 million tons of squid in the Antarctic, about 1/3 is consumed by whales, seals, and sea birds. Squid is also harvested commercially for food, bait, and other uses.

How Many Fish In The Sea? Census Of Marine Life Launches First Report The new marine fish species, being identified at an average rate of 160 per year (roughly three new species per week since year 2000), are being catalogued and mapped by the Census of Marine Life (CoML), an unprecedented cooperative initiative involving leading marine scientists from every world region.

1. Krill Facts Center Krill is comprised of two families the largest of which is Euphausiidae which contains 20 different genra, the largest of which is the Euphausia. The other family of Krill is the Bentheuphausia ampblyops, which lives in the deep waters (below 3,330 feet) and are the most primitive species of krill.

Krill Krill have been harvested as a food source for humans and domesticated animals since at least the 19th century, and possibly earlier in Japan, where it was known as okiami. Large-scale fishing developed in the late 1960s and early 1970s, and now occurs only in Antarctic waters and in the seas around Japan.

Number of blue whales in the world Keep in mind that the blue whale is the largest known animal in the world. It has 30 meters in length and 170 tons in weight. There are between 5000 to 12000 blue whales in the world. It is interesting to know the fact that blue whales are not easy to catch or kill.

The Census of Marine Life Or that there are 38,000 different kinds of microbes in a liter of seawater? These were all discoveries made by the Census of Marine Life, a 10-year international effort that assessed the diversity (how many different kinds), distribution (where they live), and abundance (how many individuals) of marine life.

What Eats Krill? Credit: hcopperm CC-BY-SA 2.0. Smaller species of seals depend on krill to survive, while larger seals, such as the leopard seal, mainly eat other animals, such as penguins and younger seals. The majority of krill are caught in the Arctic, but their numbers have decreased by at least 80 percent since the 1970s.

Antarctic Animals Photo by: H. Kaiser/NSF. Other sea creatures include animals as big as whales and as small as krill. Antarctic krill, though only six cm in size, are crucial in the Antarctic food chain. They clean up the sea by feeding in groups of thousands on phytoplankton, algae, and diatoms.

How Many Species Are There on Earth and in the Ocean? In spite of 250 years of taxonomic classification and over 1.2 million species already catalogued in a central database, our results suggest that some 86% of existing species on Earth and 91% of species in the ocean still await description.
