This document discusses different types of appendages used for locomotion in animals. It describes non-jointed appendages such as parapodia in polychaetes that also aid respiration and defense. Gastropods use muscular pedal feet and mucus to move. Cephalopods use tentacles and fins with suckers. Echinoderms use tubefeet connected to their water vascular system. Onychophora use lobopods. Jointed appendages are also discussed but not described. The document provides examples of non-jointed appendages and their functions in different animal phyla.

2. Locomotion
•Sessile/sedentary
•Free living without appendages
•Appendages/extremities: structure extend beyond
body wall
•Free living with appendages

3. Non-jointed appendages
•1. Parapodia eg.- Polychaeta
•They also helps in respiration and defense.

4. Non-jointed appendages
•2. Pedal/muscular foot eg.- Gastropoda
•They make their own road by mucus

5. Non-jointed appendages
•3. Tentacles eg.- Cephalopoda
•Fins and suckers also help in locomotion.

6. Non-jointed appendages
•4. Tubefeet: eg.- Echinodermata
•Also helps in respiration
•Also act like suckers and are connected to water
