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.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.
