Krill have the ability to shrink their bodies and undergo long periods of starvation. These adaptations allow them to survive the winter months in the Antarctic. Krill travel in swarms so dense they can actually be seen from space.

What adaptations do animals in Antarctica have?
Physical adaptations are sometimes the easiest to spot. Many of the animals living in Antarctica have outer layers of dense fur or water-repellent feathers. Under this fur or feather layer is a thick layer of insulating fat. Many marine animals have large eyes to help them spot prey and predators in the dark waters.
How do krill protect themselves?
As they grow they develop a hard exoskeleton (transparent in most species) which is used to help them defend against attacks from predators. As krill continues to grow they eventually outgrow their exoskeleton and go through a process known as moulting where they shed their exoskeleton in order to develop a new one.
How many Krills are left in the world?
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.
How do penguins survive in Antarctica?
Penguins have to keep high body temperatures to remain active. They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather. ... Waterproofing is critical to penguins' survival in water, Antarctic seas may be as cold as -2.2°C (28°F) and rarely get above +2°C (35.6°F).
How much of Antarctica is ice free?
Antarctica is a cold desert, with snowfall equivalent to only 150mm of water each year. This snow builds up gradually and ice flows towards the coast as huge glaciers. In many places, these extend out over the sea as massive ice shelves. Only about 0.4% of the surface of Antarctica is free of snow and ice.
What would happen if krill went extinct?
If the krill were to disappear, all of the creatures which feed upon them would also disappear. In general, most animals bigger than krill will eat it, from whales, seals, penguins, other seabirds and fish.
How do krill move?
Krill travel in swarms primarily as a defense mechanism to confuse predators that would pick out single krill. In additional efforts to avoid predators, krill are found to spend their day at greater depths in the ocean and rise during the night toward the surface.
What are Krills predators?
Blue whales and other large whales, leopard seals and other seals, several species of penguins, albatrosses and other seabirds, several fish species, and squids and other invertebrates all eat huge numbers of Antarctic krill.
What do Krills look like?
Krill are small shrimp-like crustaceans, with an average size of about 3.5cm in length – about the size of an ordinary paperclip – although they can reach lengths of double that size up to 6cm. ... Krill dive and rise on a regular basis and spend much of their time near the surface feeding and stocking up.
What does krill taste like?
Krill tastes salty with a somewhat stronger fish flavor than shrimp. For mass-consumption and commercially prepared products, they must be peeled to remove the inedible exoskeleton.
How do seals adapt in Antarctica?
Seals spend much of their time under the sea ice in Antarctica, experiencing the relatively 'warm' sea temperatures. ... Seals are well adapted to cold polar environments with thick blubber layers that act both as a food reserve and insulation. Most seals also have a layer of fur, giving additional insulation on land.
What flag is Antarctica?
Antarctica has no universally-recognized flag as the condominium that governs the continent has not yet formally selected one, although some individual Antarctic programs have formally adopted True South as the flag of the continent. Dozens of unofficial designs have also been proposed.
Do Penguins eat meat?
Penguins are carnivores; they eat only meat. Their diet includes krill (tiny crustaceans), squid and fish. Some species of penguin can make a large dent in an area's food supply.
