Aristotle's lantern is a characteristic of the following class of Echinodermata :
1 Echinoidea
2 Ophiuroidea
3 Holothuroidea
4 Asteroidea
Explanation:
A Aristotle's lantern is a characterstics of Sea Urchin in class - Echinoidea of phylum Echinodermata. Aristotle's lantern was first traced by Aristotle. It is involved in mastication. It is a complex arrangement of muscles and calcareous teeth and plates with forms a reversible organ in most echinoids.

Which of the following has radial symmetry in adult and bilateral symmetry in larva?
1 Annelida
2 Coelenterata
3 Echinoderms
4 Platyhelminthes
Explanation:
C In phylum Echinodermata, the larval stage is bilaterally symmetrical whereas adults are radially symmetrical. Radial symmetry is the arrangement of parts of organism around a central axis so that the organism can be divided into similar halves by any plane. Bilateral symmetry can be divided only into mirror halves through a single plane. In echinoderms larvae haves bilateral symmetry but during metamorphosis this is replaced with radial symmetry.

In Echinodermata, tube feet are related with
1 locomotion
2 excretory system
3 respiratory system
4 reproductive system
Explanation:
A Tube feet are locomotory organs of echinoderms consisting of elongated out growths of the body wall able to be protruded or retracted by alteration of fluid pressure in the water vascular system. In starfish, they are arranged in rows in ambulacral groove.
