Facts About Coral
- They have one opening surrounded by tentacles, which have nematocysts, or stinging cells, which paralyze their prey.
- The tentacles help move the food into the mouth and down into the stomach, where the food is broken down.
- In the stomach you can find membranes called mesenteries, which contain reproductive cells.
- Once the food is broken down, the waste moves out of the body back through the mouth.
- Most are nocturnal feeders because their prey, planktons, are mostly active at night.
