Question

Which one of the following is called as jumping Bivalvia?

• A. Cardium
• B. Dentalium
• C. Doris
• D. Pila

Answer 1

The correct option is A Cardium

There are certain bivalves, such as cockles (or Cardium) that move along the bottom by means of jumping. The foot of this organism is extended and then contracted violently. This movement helps in moving backward in the process. The foot in this bivalves behaves like a coiled spring. The movement of the foot helps the organisms in kicking towards the side. This foot also causes movements like sideways and forward. This appears to be like the animal is jumping.

Thus, the correct answer is option A.
