Answer

Brief Explanations:

  1. The main idea is about the narwhal, a strange - looking sea mammal. It covers its name origin, physical features (like the tusk), possible uses of the tusk, its value, population status (decreasing due to climate change and hunting limits), and its connection to the unicorn myth.
  2. The illustration might show details like the exact shape of the narwhal's body (e.g., the curvature of its back, the size and shape of its fins), the texture of its skin (more vividly than described as "death - like bluish - gray" in the text), and the exact spiral pattern of the tusk in a more visual way.
  3. The narwhal has a single long, spiral tusk (like a unicorn's horn). But the narwhal is a sea mammal (whale - like), while a unicorn is a mythical horse - like creature.

Answer:

  1. The text mainly discusses the narwhal, including its name, physical traits (such as the tusk), possible tusk functions, value, population issues, and its link to the unicorn myth.
  2. Details like the exact body shape (e.g., back curvature), skin texture, and tusk spiral pattern.
  3. The narwhal has a single tusk (like a unicorn's horn), but it is a sea mammal, while a unicorn is a mythical horse - like being.
