Question

Echinodermata have unsegmented radially symmetrical body.

• A. True
• B. False

Answer 1

The correct option is B False

In echinoderms, the adults are recognisable by their (usually five-point) radial symmetry, and include such well-known animals as starfish, sea urchins, sand dollars and sea cucumbers, as well as the sea lilies or "stone lilies". They have unsegmented body whereas segmented body is the characteristic feature of Annelida.

Therefore, the correct answer is option A.
