Final answer:
Comb jellies, or ctenophores, have radial symmetry and a diploblastic tissue arrangement. They have a complete gut and move using beating cilia. Comb jellies feed using tentacles covered in sticky adhesive and reproduce sexually.
Step-by-step explanation:
Comb jellies, also known as ctenophores, are marine animals that exhibit radial symmetry and diploblastic tissue arrangement (endoderm and ectoderm). They have a complete gut with a mouth, digestive stomach, and anus. Comb jellies move by beating cilia, which are arranged on large plates called ctenes. These ctenes propel the comb jellies through the water.
Comb jellies have feeding tentacles that are covered in sticky adhesive to trap prey. They carry out sexual reproduction, forming gametes that are expelled through the mouth. Comb jellies also have the ability to regenerate their body parts.
