The correct option is (C) Cerata
Nudibranchs, also referred to as sea slugs, are a class of marine molluscs without shells.
What is Cerata?
- Except for species like Glaucus atlanticus, which consumes nematocytes and may view you as a predator and sting, most nudibranchs are harmless to people despite the unpleasant or toxic taste they can impart to their non-human predators.
- The surface area of nudibranchs is considerably increased by cerata, which also facilitate respiration—the act of exchanging gases for metabolic usage.
- Cerata are occasionally utilized in both offense and defense. The digestive system extends into the cerata in several aeolid nudibranchs.
