Biology Question on Kingdom Animalia
Locomotory organs of annelida are
A
Suckers
B
Setae
C
Parapodia
D
All of these
Answer
All of these
Explanation
Solution
Setae and parapodia are locomotory structures in annelids. Except leeches, unjointed chitinous setae are often present. Some annelids such as Nereis have unjointed, locomotory structures, the parapodia (para-parallel, podia
- feet).
The leech bears two suckers. The anterior sucker encloses the mouth. It acts as a feeding, locomotory and prehensile organ. The posterior sucker lies at the hinder part of the body.
