Answer 2

Answer:

The absence of excretory organs, the great power of regeneration, and exclusively marine animals belong to the phylum  Echinodermata

Explanation:

• Echinoderms are a diverse group of sea creatures. Sea urchins, sea cucumbers, and starfish are among the most well-known members of this phylum. Echinoderms do not have main excretion organs and instead excrete nitrogenous waste in the form of ammonia through their respiratory system.
• They reproduce both sexually and asexually through gametic fusion and regeneration. Fertilization is a process that occurs outside of the body.
• The excretory system is absent, and they have a simple radial nerve system.
