Pearl Oyster
The pearl oyster may be the most amazing creature in the ocean. It goes down to the depths where it remains inside a shell made of a hard substance that protects it from danger, and it differs from other living beings in its structure and the way it lives. It is a fine net like a fishing net, wonderfully woven. It acts like a sieve which allows water, air and food to enter it, but keeps out sand and pebbles and so on. Beneath the net are the mouths of the animal, and each mouth has four lips. If a grain of sand or piece of pebble enters it, or a harmful animal enters the shell by force, the oyster hastens to excrete a viscous substance that covers it and then solidifies, forming a pearl. The size of pearls varies depending on the size of the grain of sand.
This is one of many thousands and millions of types of primitive sea creatures, and Allah, the Exalted, knows best. (Allah Wal-‘Ilm Al-Hadith by ‘Abd Al-Razzaq Nawfal)
