Answer:

“Crab and snail” both are having a protective covering and is not made of same material.

Explanation:

  • Crab composed of iron sulphide in the outer layer while snail’s outer wall is made of calcium carbonate.
  • This calcium carbonate will dissolve and the snail let as bare body in water.
  • This crab is the three-layered armour.
  • These are based on fossil record analysis.
  • So, that the crab and snail’s protective covering is made of different material.
