The reef's rocky sandstone outcrops, submerged beneath 60 to 70 feet (18 to 21 m) of water, can be as tall as 2 to 3 metres (6 ft 7 in to 9 ft 10 in) and are highly complex. [2] These nooks and crannies provide plenty of places for marine invertebrates to latch on to and for fish to hide in. Together these animals form a dense tapestry of ...
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 ...
Synalpheus regalis is a species of snapping shrimp that commonly live in sponges in the coral reefs along the tropical West Atlantic. [3] [4] They form a prominent component of the diverse marine cryptofauna of the region. [3] For the span of their entire lives, they live in the internal canals of the host sponge, using it as a food resource ...

The giant barrel sponge has been called the "redwood of the reef" [4] because of its large size and its long lifespan, which can be more than 2,000 years. [5] It is, perhaps, the best-studied species of sponge in the sea; a population on Conch Reef , in the Florida Keys , has been monitored and studied since 1997.
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.
Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules, often referred to as glass sponges. They are usually classified along with other sponges in the phylum Porifera , but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma .
Live rock prior to installation into a reef tank In J. Charles Delbeek's article Your First Reef Aquarium , [ 2 ] he states, The use of live rock immediately introduces into the aquarium numerous algae, bacteria and small invertebrates all of which contribute to the overall quality of the aquarium water.
