Why maxillipeds are fringed with hair-like structures called setae?
Maxillipeds are fringed with hair-like structures called setae to enhance their sensory capabilities and improve their feeding efficiency. These setae can detect chemical signals in the water, helping the organism locate food sources and navigate its environment. Additionally, the setae can aid in the manipulation of food particles, allowing for more effective processing during feeding. Overall, the presence of setae contributes to the survival and adaptability of the organism in its aquatic habitat.

What are setae and what are their importance is?
Setae are small, bristle-like structures found on the body of some animals, such as insects and worms. They are important for sensory perception, movement, and protection. Setae can help the animal detect changes in its environment, navigate through its surroundings, and ward off predators.
Are worms smooth?

Are the small openings on a sponge called setae?
