Answer:
three identifying characteristics of arthropods are: " Jointed appendegas", "segmented" and bilateral symmetry"
Example: Scorpions have 8 jointed legs and a pair of pedipalps that are used for grasping prey and sensing.
Example: Leechs have soft, muscular, segmented bodies that can lengthen and contract.
Example: Starfish must use its body to move quickly, and its fleeing behavior strongly reflects its bilateral propensity.
