Question

Bipinnaria is the larva of Mollusca.State if it is True or False?

Answer 1

Bipinnaria is the larva of Mollusca.....

This statement is FALSE.

Reason:

Bipinaria is a kind of starfish larva and not the Mollusca larva.

A Bipinaria is the first stage in the larval development of most starfish, and is usually followed by a brachiolaria stage. Starfish that develop their young usually lack a Bipinaria stage, developing directly into miniature adults with eggs.

Answer 2

Answer:  

False. Bipinnaria is not the larva of Mollusca.  

Explanation:  

Bipinnaria is depicted as the very first stage of the larval form of different Starfishes. This belongs to a different phylum than Mollusca. The larva of Mollusca is known as veliger that develops from a trochophore.

Veliger is typical of different snails of marine origin and in a number of bivalves present in freshwater. In starfishes, the bipinnaria is converted to a stage of brachiolaria.
