Front 7

What does a madreporite do?

Back 7

1. regulates water coming in and out of the system.

Front 8

How does the water vascular system work?

Back 8

1. Made of many canals ( ring canal, radial canal, stone canal)
2. Water comes in/out of madreporite and it helps with suction.
3. When eating clams, it becomes a battle of time until ATP in clams runs out and they open easily.
