 water-driven tube system that they use for moving around?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. Echinodermata

  • The group of animals named because of their spiny skin and characterized by a peculiar water-driven tube system for movement are "Echinoderms."
  • Echinoderms include animals like sea stars (starfish), sea urchins, sea cucumbers, and brittle stars. They have a unique water vascular system that they use for locomotion, feeding, and respiration.
  • This system uses water pressure to operate tube feet, which extend and retract, allowing echinoderms to move and perform various functions.
  • Echinoderms are primarily marine animals and are known for their distinctive appearance and ecological roles in marine ecosystems
