• These are mostly aquatic or marine habitat animals.
• These species exhibit a tissue-level organization.
• The mouth is enclosed by thin and short tentacles.
• They are diploblastic animals, in which, the body is made up of two layers of cells:
• Ectoderm – One layer makes up the cells outside the body
• Endoderm – the other forms the inner lining of the body.
• They have cavities in their body.
• The body is radially symmetrical.
• The digestion is both intracellular and extracellular.
• The nervous system and the circulatory system is absent.
• They excrete and respire through simple diffusion.
• The mode of reproduction is asexual, which is through budding.
• The sexual mode of reproduction is seen only in a few Coelenterates.
