Answer 2

Answer:

The marine animals termed echinoderms belonging to Phylum Echinodermata of Kingdom Animalia have spiny bodies.

Explanation:

• ‘Echino’ in Greek means ‘spiny skin’. Echinoderms are mostly invertebrate marine animals like starfish, sea urchin, sea cucumber etc.
• The spines are part of their adaptation that acts as a defence mechanism to protect themselves from their predators.
• Some species also release toxins from these spines to protect themselves.
• The spines are part of their exoskeleton made up of minerals like calcium.
• Echinoderms use their spines for protection from predators, locomotion, to catch their prey, reproduction, feeding, etc.
