More than 8000 species of sea sponges live in oceanic and freshwater habitats. [1] Sponge fishing historically has been an important and lucrative industry, with yearly catches from years 1913 to 1938 regularly exceeding 181 tonnes and generating over 1 million U.S. dollars. However, this demand for sea sponges has seen catch rates peak and in ...
Each living sponge on the surface of the reef can be over 1.5 m tall. The reefs are composed of mounds called "bioherms" that are up to 21 m high, and sheets called "biostromes" that are 2–10 m thick and may be many kilometers wide. [5] Each sponge in the order Hexactinosa has a rigid skeleton that persists after the death of the animal.
Hydnoceras species were suspension feeders, and likely remained attached to a single substrate for their entire lives, as typical for a sponge. [3] Unlike modern glass sponges, which typically live in deep marine environments, these sponges lived throughout the marine water column.
Flow tank experiments suggest that archaeocyathan morphology allowed them to exploit flow gradients, either by passively pumping water through the skeleton, or, as in present-day, extant sponges, by drawing water through the pores, removing nutrients, and expelling spent water and wastes through the pores into the central space.

Glass sponges such as Claviscopulia are found worldwide in both hard and soft substrates and in the deeper part of the sea ranging from around 200m to more than 6000m. In some cases, glass sponges live in shallower areas like the submarine caves in Mediterranean or off the coast of British Columbia.
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.
Marine invertebrates are invertebrate animals that live in marine habitats, and make up most of the macroscopic life in the oceans. It is a polyphyletic blanket term that contains all marine animals except the marine vertebrates , including the non- vertebrate members of the phylum Chordata such as lancelets , sea squirts and salps .
All sponges in this class are strictly marine, and, while they are distributed worldwide, most are found in shallow tropical waters. Like nearly all other sponges, they are sedentary filter feeders. All three sponge body plans (asconoid, syconoid, and leuconoid) can be found within the class Calcarea. Typically, calcareous sponges are small ...
