Discovery


About the flower crab

I find flower crabs very special to me because when the shell is too small, it will come out of its old shell, this is called moulting! How does it moult?

It grows a new shell which is still soft, puffs itself with water until its shell hardens and finally releases the water so that it will have more space to grow.
Soft shell crabs
Do you know that fisherman only catch the crab, when it is moulting? That's because its shell is soft at that time!
