Krill need ice for various reasons, including shelter and protection from predators, as well as a habitat for their food source like algae and phytoplankton. Ice also provides a physical structure for krill to attach their eggs, ensuring their successful reproduction and survival.

How is global warming threatening the lives of Antarctic animals?
Global warming is affecting Antarctic animals by causing their habitats to melt and shrink, such as sea ice for species like penguins and seals. Changes in temperature also disrupt their food sources, like krill and fish, leading to food shortages. Additionally, the warming ocean waters are affecting the ecosystem balance and increasing the risk of disease outbreaks among marine animals.
Do krill eat diatoms?
Yes, krill do eat diatoms. Diatoms are a type of microscopic algae that krill feed on as part of their diet. These tiny plants are an important food source for many marine organisms, including krill.
How much do krill weight?
krill are about 4-5cm long when fully grown
How does melting sea ice affect penguins?
Some penguins, like Emperor Penguins, breed and raise their young entirely on sea ice. When sea ice melts earlier at the end of winter this disrupts the breeding season. Another problem is that the penguins' food source, krill and other tiny crustaceans, survives on phytoplankton and zooplankton that grow on the ice. As the ice disappears, so does the plankton, disrupting the food chain.
Do tiger sharks eat other sharks?
Yes
Why are baby penguins going hungry?
it is basically because of greenhouse gases. the earth is getting hotter so it melts the ice in antarctica. The krill that the penguins feed on live in the ice, in bubble which have algae which the krill feed on. but because there is less ice, the krill die meaning the penguins go hungry.
What do ice fish mostly eat?
I think it eats krill
Why is the macaroni penguin population declining?
Macoroni penguins feed on Krill and Krill feed on plankton that grow under the sea ice shelves and due to climate change there is less ice on the Antarctic Ocean. This reduction in sea ice leads to reduction in Krill Population, and the numbers to reach adult stage has decreased significantly because without sea ice the larvae starve (Atkinson et al, (2004). So less Krill means a decline in macaroni penguins.
Is climate change already affecting penguins in Antarctica?
Yes. Phytoplankton (algae) grow under the ice shelves of Antarctica. Warmer water is affecting the growth of phytoplanktons. Krill (zooplankton) need them to survive. These two are vital links in the food chain of the Antarctic. Penguins need krill and the fish that feed on krill. Climate change is damaging the food chain in Antarctica and threatening the lives of all the animals there, including the penguins.

What does fairy penguins eat?
Fairy Penguins eat mostly fish, squid, and krill.
Why are krill numbers shrinking?
Krill numbers are shrinking due to a combination of factors including climate change affecting their habitat, overfishing, and changes in ocean chemistry. These factors can impact krill populations by affecting their food sources, breeding grounds, and overall survival rates.
Zooplankton is eaten by?
fish and krill fish and krill fish and krill fish and krill fish and krill
What does the antarctic ice fish eat?
Antarctic ice fish primarily feed on krill, small fish, and amphipods. They have evolved unique adaptations to survive in the cold waters of Antarctica, such as specialized digestive enzymes to help them digest the high-fat content of their prey.
How do you say krill in German?
krill = Krill
Why do krill stay in a group?
yes then do stay in groups and their early life is spent under a ice pack in the artic region.
What types of fish live in Antarctica?
lots of types of fish live in Antarctica such as the ice fish and the krill fish
