Answer:
The characteristics that is not true for all specimens of Phylum Arthropoda is "Body divided into winds, head, jointed appendages."
While many arthropods do have wings, not all of them do. In fact, the presence of wings is specific to certain groups within the phylum, such as insects. Other arthropods, like spiders and crustaceans, do not have wings. Therefore, the presence of wings is not a universal characteristic for all specimens of Phylum Arthropoda.
