The hypothesis has been made that coral reef sponges facilitate the transfer of coral-derived organic matter to their associated detritivores via the production of sponge detritus, as shown in the diagram. Several sponge species are able to convert coral-derived DOM into sponge detritus, [62] [63] and transfer organic matter produced by corals ...
The mineral composition of sponge spicules makes these structures the most resistant parts of the sponge bodies [79] and ensures the ability of spicules to withstand various taphonomic processes, [86] [101] resulting in that they often constitute the only evidence of the presence of some sponges in an ecosystem.

Callyspongia (Cladochalina) aculeata, commonly known as the branching vase sponge is a species of sea sponge in the family Callyspongiidae. [1] Poriferans are typically characterized by ostia, pores that filter out plankton, with an osculum as the opening which water leaves through, and choanocytes trap food particles.
About 311 million years ago, in the Late Carboniferous, the order Spongillida split from the marine sponges, and is the only sponges to live in freshwater environments. [8] Some species are brightly colored, with great variety in body shape; the largest species are over 1 m (3.3 ft) across. [ 6 ]
Aplysina cauliformis, also known as the row pore rope sponge or rope sponge, is a species of sea sponge in the family Aplysinidae. [3] It is commonly found in shallow reefs across the tropical Atlantic Ocean , including the Caribbean Sea and the Gulf of Mexico . [ 4 ]

Halichondria is a genus of sea sponges belonging to the family Halichondriidae. [1] [2] These are massive, amorphous sponges with clearly separated inner and outer skeletons consisting of bundles of spicules arranged in a seemingly random pattern.
