Question

Echinoderms show______________.

• A. Bilateral symmetry
• B. Radial symmetry
• C. Asymmetry
• D. None of the above

Answer 1

The correct option is A Bilateral symmetry

Echinoderms take many forms of symmetry.

Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians.

Echinoderm larvae are bilateral during their early development.

So, the correct answer is 'Bilateral symmetry'.
