Question

Ctenophores exhibit

• A. Radial symmetry
• B. Asymmetry
• C. Biradial symmetry
• D. Bilateral symmetry

Answer 1

The correct option is C Biradial symmetry

• Ctenophora are also known ascomb jellies. This is a phylum of animals that lives in marine waters.
• Many species in this group have the body which is biradially symmetrical. The main axis is oral to aboral (from the mouth to the opposite end). This gives the bilateral form.
• The tentacles are present around the mouth. These tentacles radiate outwards. This gives the radial form of symmetry. Thus, the type of symmetry is known as biradial symmetry.
  

Therefore, the correct answer is option C.
