Correct Answer - Option 4 : All of the above

The correct answer is option (4) i.e. All of the above.

  • Shells are important to these islands because some like Turbo, Trochus & Nautilus etc. are being used as novelties supporting many cottage industries producing a wide range of decorative items & ornaments.
  • Shells such as Giant clam, Green mussel and Oyster support edible shellfishery, a few like Scallop, Clam and Cockle are burnt in kiln to produce edible lime.
  • The Univalve or one shell group belongs to the class Gastropoda having more than 80,000 species. Sacred Chank belongs to this group.
  • The soft body animal, which lives inside the shell, is covered with a thick layer of specialised epithelium cells known as rnantle, which in turn secretes a two tier shell material making the shell.
