Question 19: Which one of the following class of phylum mollusca is incorrectly matched with its general characteristics?
(a) Gastropoda – Larvae are bilaterally symmetrical; but in adult, the twisting of viscera makes them lose this symmetry. Some, like land snail and slug (a shell-less form), live on land.
(b) Bivalvia – They are sedentary filter feeders.
(c) Cephalopoda – They are at the apex of invertebrate evolution in terms of learned behaviour they exhibit. The eyes are image forming, same what similar to ours.
