Answer 2

The incorrect statement about spinny skinned animals is an option (3).

• Echinodermata is known as spiny skinned organisms.
• Their development includes larva formation and development is direct which means their larva directly grows in adult form without any middle stages.
• Their larva is radially symmetrical i.e can be divided into equal halves in any plane while adults can be divided into equal halves in one plane only. So, adults are bilaterally symmetrical.
• They have a water vascular system.
• The water vascular system is used for food transport, locomotion and respiration. example- sea star.
