CORAL POLYPS

Coral polyps are tiny animals that range from the size of a pinhead to larger than a basketball.

Polyps have tentacles to catch food such as microplankton to bring into the mouth.

The tentacles are covered in nematocysts, stinging cells which paralyze their prey.

 

AN INSIDE LOOK

Polyps are mostly stomach.

Once they catch prey through their tiny mouth, it is digested by the stomach.
