They live in oceans because they have to live in salt water.
Whales survive by eating krill.
Krill survive in the Southern Ocean which surrounds the Antarctic continent.
to poo
No because they can only survive in salt water.
Antarctica is a continent and krill are sea animals. The liquid sea is always warmer than the ambient temperature in Antarctica. The cold Southern Ocean is a natural habitat for krill.
Krill breathe through gills located on their abdomen. They extract oxygen from the water as it passes over these gills, allowing them to respire and survive underwater.
no i don't think so i believe they only live in the ocean Krill are salt water animals, they cannot survive in a fresh water swamp
Phytoplankton and krill have adaptations that help them survive in their environment. Phytoplankton can sense light and move towards the surface where they can photosynthesize. Krill have a high concentration of hemoglobin, which helps them utilize oxygen efficiently in cold waters. These adaptations contribute to their ability to survive and thrive in their respective habitats.
The Fin Whale mainly relies on krill to survive.
Euphasia surperba, Antarctic krill, survive in water ranging from −1.3 to 3 °C (29.7 to 37.4 °F). If the animal wants 'warmth', it moves into warmer water.
Well, they have to eat that much or they won't survive/ they won't be satisfied and happy. But I don't think that they eat krill, I think it's plankton...
Krill adaptations are certain characteristics of krill that help it survive. For example, female krill can lay 1000 eggs at one time. This helps increase the population.Also they travel in schools of over 5000 to make it difficult to be eaten.
