Which of the following is not considered an adaptation to aquatic life?

  1. Streamlined body

  2. Blubber

  3. Gills

  4. Wings

The correct answer is: Wings

Wings are not considered an adaptation to aquatic life because they are specifically designed for flight, not for survival in water. Streamlined body, blubber, and gills are all adaptations for aquatic life. Streamlined body helps with hydrodynamics and allows for efficient movement in water. Blubber is a layer of fat that provides insulation and helps keep aquatic animals warm. Gills are used for respiration and are essential for survival in water. Therefore, D is the only option that is not considered an adaptation to aquatic life as it is not relevant to life in water.
