Reef Balls

“A reef ball is a designed artificial reef module which mimics the structure and function of a natural reef.”… Hollow interior spaces provide habitat and shelter for marine species, and the addition of coral plugs allows for quick initiation of growth and rescue of corals damaged by storms, dredging, etc.”… The Reef Ball Foundation is a 501(c) 3 publicly supported non-profit and international environmental NGO whose mission is to help restore and conserve oceanic and aquatic habitats using Reef Ball technologies.”

Some companies offer the opportunity to incorporate cremated ashes into reef balls and let loved ones spend time decorating the reef ball with handprints and similar objects.
