How are dogs and penguins different?

Answer 1

Dogs and penguins differ significantly in their classification and habitat. Dogs are mammals belonging to the Canidae family, characterized by their ability to live on land and their domestication by humans. In contrast, penguins are birds in the Spheniscidae family, adapted for life in aquatic environments, primarily in the Southern Hemisphere. Additionally, while dogs are warm-blooded and have fur, penguins are cold-blooded with feathers and a streamlined body for swimming.
