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 ...
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.
Found burrowing in mud or sand flats in the wild, they need a deep sand bed in their aquarium. 60 cm (23.6 in) Sea spider [3] Pycnogonids: No: Not collected for the aquarium trade, but occasionally seen on live rock and corals as a hitchhiker. They can be pests in a reef tank, preying on soft coral, sponges and anemones. 0.2–50 cm (0.1–19.7 in)
Sponges in temperate regions live for at most a few years, but some tropical species and perhaps some deep-ocean ones may live for 200 years or more. Some calcified demosponges grow by only 0.2 mm (0.0079 in) per year and, if that rate is constant, specimens 1 m (3.3 ft) wide must be about 5,000 years old.
By all spawning at the same time, the sponges maximize their reproductive success. The eggs are surrounded by a mass of nurse cells which may provide nutrients to the developing larvae. The orange elephant ear sponge also reproduces asexually. When pieces of sponge become detached they may later reattach themselves to the substrate. [6]
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 ...

Sponges with a larger openings and smaller bases are less prone to breakage and live easier in shallower water than sponges with thin, narrow branches. [ 5 ] Sponges are hermaphroditic, and members of demospongiae can develop sexually produced larvae or from asexual fragments.
