The tusked whale is a type of whale that is characterized by its long, spiral tusk. The two most common species of tusked whales are the NARWHAL (7 letters) and the Narwal (6 letters). Both species are found in the Arctic Ocean and are known for their unique tusks, which can grow up to 8 feet long. They are also known for their diet of fish, squid, and shrimp. Narwhals are particularly vulnerable to climate change due to their reliance on sea ice for hunting and migration.
