📚 Practice ConceptExamples: Physalia (Portuguese man-of-war), Adamsia (Sea anemone), Pennatula (Sea-pen), Gorgonia (Sea-fan) and Meandrina (Brain coral).
Consider the following statements: 1. Locusta is a gregarious pest and belongs to phylum Arthropoda. 2. Physalia (Portuguese man-of-war) uses cnidoblasts for defense and prey capture. 3. Wuchereria (Filaria worm) causes filariasis in humans and is dioecious. 4. Limulus is known as a “living fossil” among arthropods. 5. Ascidia shows notochord only in its larval tail. Which of the above are correct?
