Narwhals: Unicorns of the Sea!

The video explores the unique characteristics of narwhals, focusing on their tusks. Narwhals are known for their long, unicorn-like tusks, which are actually elongated teeth. These tusks grow through the narwhal's head and are used for sensing the environment, communication, and hunting. While all male narwhals have tusks, only some females do. The video also highlights the challenges scientists face in studying narwhals due to their shy nature and remote Arctic habitat. Despite these challenges, scientists have discovered that narwhals use their tusks to interact with each other and catch fish, though many mysteries remain.

What similarities and differences exist between narwhal tusks and the tusks of other animals like elephants?

Why is it difficult for scientists to study narwhals in their natural habitat?
