No. Phylum arthropoda is characterized by joint appendages such as you might see in insects, lobsters, etc... they are all invertebrates with exoskeletons. By contrast, penguins are chordates (phylum chordata), including the subphylim Vertebrata which has an internal skeleton including a spinal cord.. this includes mammals, fish, reptiles, and of course, birds like the penguin.
