Cliona celata, occasionally called the boring sponge, is a species of demosponge belonging the family Clionaidae. It is found worldwide. This sponge creates round holes up to 5 millimetres (0.20 in) in diameter in limestone or the shells of molluscs, especially oysters. The sponge itself is often visible as a rather featureless yellow or orange lump at the bottom of the hole.

Mating Habits

This animal can reproduce asexually and sexually. They can simply separate by mitosis, as single cells do, or they can release sperm into the water in hopes of them finding a female's eggs. They may also attach their larvae onto mollusks like clams and mussels. This usually results in the death of the host. They then will begin to grow and colonize..
