How do orcas survive in antarctica?

Answer 1

The way blue whales and other baleen whales adapt to their environment is by using blubber. Blubber is made from "fat cells and fibrous connective tissue". Blubber is an energy reserve, and it insulates a whale, from the cold ocean in Antarctica. Blue Whales can maintain a core body temperature similar to that of other large mammals, around 36.6 to 37.2 degrees Celsius. There is a "heat gradient throughout the blubber to the skin". This blubber makes the whale's body streamlined or in a fusiform (torpedo shape), and it also makes up 27% of their weight. This shape also exposes less surface area to the outside environment, therefore conserving body heat. Another way baleen whales have adapted to these cold climates is by having veins surround some arteries in their flukes and dorsal fin. The heat from the blood passing through the arteries transfers to the veins, rather than the surrounding environment. This is known as countercurrent heat exchange, and it also helps the whales conserve body heat. To decrease circulation is to conserve body heat, so when a whale dives blood is "shunted away from the surface.

Answer 2

• Orcas can survive in Antarctica because They have a thick layer of blubber to keep them warm and they migrate north for the winter when it gets cold an there is less krill to feed on.

Answer 3

Antarctica is a continent, 98% of which is covered with an ice sheet. Sharks live in liquid sea water which is warmer than the ice sheet on the continent. Two species of shark include Antarctica in their names: Mustelus antarcticus, the Gummy shark, and Somniosus antarcticus, the Southern Sleeper shark

As of 2008, the University of Rhode Island proposed that if the Southern Ocean continued to warm, more species of sharks may visit.

Answer 4

Only male sperm whales can be found in Antarctic waters but generally this species of whale lives elsewhere.

Answer 5

they usually have thick coats or adapt easily to harshly cold environments...btw, does should be do

Answer 6

They do not go to the antarctic so will not need to adapt to those conditions.

Answer 7

well the blue whale eats krill and lollipops

Answer 8

Krill survive in Antarctic waters because that is their natural habitat.

Answer 9

with there fur
