Correct Answer: Option E
Explanation:
The correct answer is E. Shark.
Sharks are vertebrates and do not exhibit metameric segmentation in the same way as invertebrates like earthworms, centipedes, and crayfish. While vertebrates do have segmented muscles and skeletal structures, the kind of metameric segmentation seen in these invertebrates (which is the repetition of body segments along the length of the body) is not a feature of sharks.
