Open in App
Solution
The correct option is C Parapodia
Annelids may be terrestrial or aquatic (marine and fresh water) in habitat. Some like the leeches are parasitic. Terrestrial annelids like earthworm, locomote by stretching and contracting their muscles, while a few aquatic annelids like Nereis have parapodia - leg like appendages attached to each segments. They help in swimming. Tentacles are seen in animals that belong to the phylum Cnidaria which help in locomotion and capturing prey.
Nephridia are special excretory organs in annelids. The nervous system of Annelids have a pair of ganglia which represents the brain and they have nerves that are connected to a double nerve cord that is on the ventral side or in the front.
