What adaptations do Narwhals Have???

In order for narwhals to communicate through the deep, icy waters of the arctic ocean, they adapted a much higher range of echo location which consists of very high clicks, squeals, and whistles..Narwhals adapted a very flexible neck in order to scan the deep waters of the arctic better. This allows the narwhal to capture more prey.Another adaptation that narwhals have is that they are able to hold their breath for up to twenty minutes in order to dive down and hide from predators such as orcas, walruses, and polar bears.Narwhals are also able to survive the cold waters of the arctic because of their thick layer of blubber that retains heat.Narwhals do not swim very fast because their flippers are not very well developed and they lack dorsal fins.
