What are three adaptations for narwhal survival?

Answer 1

Structural adaptations - Body parts of an organism that helps it to survive Tusks The narwhal's tusks makes holes in sea ice and uses it to determine sea ice thickness. Physiological adaptations - are systems present in an organism that allow it to perform certain biochemical reactions Hydrodynamic sensor capabilities Ten million tiny nerve connections tunnel their way from the central nerve of the narwhal tusk to its outer surface, therefore making the horn capable of detecting changes in water temperature Behavioural adaptations - ways a particular organism behaves to survive FeedingFeed in winter because of low productivity in the high arctic summers and to avoid competition with other whales that feed in summer Maintaining energy In winter Narwhals stay in a fairly limited area for 6 months and make small movements to maintain energy Migration Narwhals migrate tothe north and north-east into the ice fields of the Greenland Sea during May-July to move towards coastal areas which are ice free

Answer 3

Protective markings that blend into the play of light and shadow in the sunlit, upper Arctic and North Atlantic waters is one adaptation for narwhal survival. A second adaptation is the lack of a dorsal fin. Without that fin, the narwhal [Monodon monoceros] can hide in icy crevices that can't be entered by killer Orca whales [Orcinus orca]. A third adaptation is the male narwhal's frontwards projecting, long tusk. The exact use of the tusk still is being researched by scientists. But the tusk may be used for sensing underwater pressures and temperatures, and for navigating by echolocation.

Answer 4

it has alot of blubber to keep it from getting cold
