Which of the following is NOT a characteristic of chordates?

Step 1: Understand what chordates are. Chordates are animals that belong to the phylum Chordata, which includes mammals, birds, reptiles, amphibians, and fish.
Step 2: Identify the main characteristics of chordates. These include having a notochord (a flexible rod), a dorsal nerve cord, pharyngeal slits, and a post-anal tail at some stage of their life.
Step 3: Recognize what an exoskeleton is. An exoskeleton is a hard outer structure that provides support and protection, commonly found in insects and crustaceans.
Step 4: Compare the characteristics. Chordates typically have an internal skeleton (endoskeleton) made of bone or cartilage, not an exoskeleton.
Step 5: Conclude that an exoskeleton is NOT a characteristic of chordates.
