Admin How do Narwhal get their food?
Narwhal feed primarily on Greenland halibut, Arctic cod, cuttlefish, Polar cod, squid, and shrimp. Scientists believe that they feed by using strong suction to force prey into their mouths. These animals only have two canine teeth, one of which is a tusk, so it is unlikely they can capture prey in any other way.
What body parts do narwhals use for survival?
Deep water adaptations aid the narwhal Due to some key adaptations, narwhals can survive at truly staggering depths. They have a flexible rib cage, enabling their bodies to be highly compressed. Once their rib cage compresses, their lungs “collapse,” and the air inside is channelled into their trachea system.
What helps a narwhal survive?
Narwhals are well adapted to the arctic marine environment in which they live. Narwhals have a streamline body with two dorsal flippers and lack a dorsal fin. Propulsion comes from their tail. They have a thick layer of blubber to protect their bodies from the cold (Williams et al.
Why is the narwhal important to its ecosystem?
Why They Matter. Whales, like the narwhal, are at the top of the food chain and have an important role in the overall health of the marine environment. Like polar bears, the narwhal depends on sea ice for its existence and can be directly impacted by climate change.
What do narwhals use their horns for?
Martin Nweeia’s investigations, in combination with Inuit observations and traditional knowledge, have revealed that the tusk may be a sensory organ. Narwhals may use their tusks to detect temperature, water pressure, particle gradients, and motion.
Why are narwhals important to the ecosystem?
How do narwhal respond to their environment?
Migration towards shallower water around coasts in the summer when the females give birth and then further offshore in the winter (behavioural) – In the winter narwhals move offshore into deeper water where they live amongst open water leads, long strips of ice free areas through the thick pack ice or in polynyas.

What is a narwhal known for?
Long, white tusks break the surface of the icy Arctic water. It’s not a waterlogged herd of unicorns—it’s a pod of narwhals! This species of whale is best known for its tusk—a long, spiraled tooth that usually only the males develop.
