Sponges also play a role in increasing the survival of live coral on Caribbean reefs by binding fragments together and is expected to increase the rates of carbonate accretion. [ 13 ] The coral reefs that contain higher amounts of sponges have better survival rate than the reefs with fewer sponges.
Giant Barrel Sponges filter a tremendous amount of water throughout their lifespan (some living up to 2000 years) which increases water clarity, controls algae, and affects coral populations. These sponges also serve as a habitat for many other species such as other invertebrates, benthic fish, bacteria, and cyanobacteria.
The sponges form reefs (called sponge reefs) off the coast of British Columbia, southeast Alaska and Washington state, [15] which are studied in the Sponge Reef Project. In the case of Sarostegia oculata, this species almost always hosts symbiotic zoanthids, which cause the hexactinellid sponge to imitate the appearance and structure of coral ...
The increase mass coral dead zones is reinforced by the spread of coral diseases. Coral diseases can spread easily when there are high concentrations of sulfide and hypoxic conditions. Due to the loop of hypoxia and coral reef mortality, the fish and other marine life that inhabit the coral reefs have a change in behavioral in response to the ...
Sponge reefs are reefs produced by sea sponges. All modern sponge reefs are formed by hexactinellid sponges, which have an endoskeleton made of silica spicules and are often referred to as "glass sponges", while historically the non-spiculed, calcite-skeletoned archaeocyathid and stromatoporoid sponges were the primary reef-builders.
Organic matter could be transferred from corals to sponges by all these pathways, but DOM likely makes up the largest fraction, as the majority (56 to 80%) of coral mucus dissolves in the water column, [65] and coral loss of fixed carbon due to expulsion of Symbiodinium is typically negligible (0.01%) [68] compared with mucus release (up to ~40%).

Beautiful elephant-ear, basket, tube, and rope sponge are found on the edge of this trench with shades of red, pink, yellow, and orange colors as well as enormous trees of black coral and gorgonia. The walls contain many overhangs and ledges and are home to lobsters, king crab, green and spotted moray eels, and a host of other marine creatures.
