These colonies of sponges kill the living tissue of th coral, excavate the upper layers of the coral skeleton. These sponges secrete acid that dissolves and chips away at the coral skeletons. Location: Klein Island, Bonaire part of the Caribbean Netherlands and part of the Leeward Antilles, January 2021.
