Fun Facts about the Watermelon Mushroom Coral

• This coral has one mouth opening that is round and has warts on it. The tentacles around the margin of the mushroom can be longer to aid in grabbing food.

• It’s a semi-aggressive species if near or touching another coral. They do not have a potent sting, but direct contact with another coral will cause damage.    .

• Coral reproduce in four different ways. The first three ways are asexual budding, laceration, and division/fission. The fourth way is through sexual reproduction where eggs and sperm are released into the water column.
