Barrel sponges are one of the oldest existing marine creatures on earth. Their main habitat is the coral reef in the Caribbean Sea. These sponges are also found in places like the Bahamas, Bermuda, Florida, and the Gulf of Mexico. Most extensive studies on giant barrel sponges have been performed off the Florida Keys islands.
Barrel sponges grow in marine water at a depth of anywhere between 33-390 ft (10-120 m). The colors of the sponge change given how deep it is. At a shallow height, closer to the surface, barrel sponge populations are brown-red or brown-gray. But at a greater depth, populations change color to salmon pink and purple due to the proximity to bacteria known as 'cyanobacteria symbionts'. Barrel sponges have porous bodies and this comes in handy when filter-feeding, wherein they filter water through their bodies and trap the suspended food particles. They form an important part of the coral reef ecosystem, helping the microscopic bacteria with carbon fixation and nitrification processes. The giant barrel sponge, itself one of many invertebrates, is a food source to other invertebrates like the parrotfish and to other fish such as cardinalfish and gobies.

The barrel sponge (Xestospongia muta) or the giant barrel sponge is a sponge.
The giant barrel sponge belongs to the 'sponge' or 'Demospongiae' class of animals.
The exact number of barrel sponge (Xestospongia muta) organisms in the world is unknown, but it is one of the oldest species to exist, having been around for more than 500 million years!
The giant barrel sponge (Xestospongia muta) lives mainly in the seas and oceans, predominantly in the coral reef of the Caribbean Sea.
The giant barrel sponge (Xestospongia muta) lives on the coral reefs of oceans, mainly in the Caribbean Sea. It may be found at 33 ft (10 m) below the surface of the sea, or as deep as 390 ft (120 m). Barrel sponges are very common in coral reefs off the Florida Keys islands as well as in coral reefs in the Pacific and Indian oceans. Also, in the coral reefs of the Pacific and Indian oceans, two adjacent barrel sponges may be found that are exactly identical to each other. Barrel sponges and giant barrel sponges can grow on any tough and hard surface in the coral reefs.
Barrel sponges live mostly in solitude, but it is not uncommon to find clusters of them together.
Barrel sponges can stay alive for a very long time, even centuries and millennia. Average giant barrel sponges are typically 150-200 years old. On the Conch Reefs (coral reefs near the Florida Keys), giant barrel sponges are at least 130 years old. The single biggest sponge, which is now known to be dead was 2,300 years old!
A giant barrel sponge (Xestospongia) has a singular method of reproducing. The sponges emit considerable quantities of eggs and sperm into the water column from their osculum, and these sperm and eggs meet on the reef and spawn. Their larvae are taken away in different directions by the currents of the sea or ocean.
The conservation status of giant barrel sponges is unclear since they haven't been evaluated by the International Union for the Conservation of Nature for their Red List.
Barrel sponges are underwater organisms, typically seen growing on a coral reef in the marine waters of the Caribbean Sea. They are shaped like a barrel, a cylindrical one, and are very big in size, with an average diameter of 6 ft (1.8 m) and a height of 8 ft (2.5m). The giant barrel sponge species is known by the moniker 'redwood of the ocean', due to evidence of them being really large and as old as hundreds and thousands of years.
Giant barrel sponges can be considered cute, as they are strikingly beautiful in appearance. They are stationary beings that eat suspended food particles in water and they exist in multiple colors such as brown-gray, brown-red, and even a stunning purple.
Barrel sponges do not communicate with each other, since they don't have a nervous system.
Giant barrel sponges can grow to be very big, as big as 8 ft (2.5 m), which is 25-35 times bigger than a typical sea urchin.
Barrel sponges are bound to the reef and cannot move.
Considering the weight of the water that they retain at any given time, barrel sponges can weigh up to 180 lb (80 kg).
Barrel sponges do not have specific names for males and females.
There is no particular name for young of the barrel sponge species, but the male sperm and the female eggs do meet to form larvae, which mature into adult sponges.
Barrel sponges are filter feeders, meaning they filter marine water through their highly porous bodies, and they retain the suspended particles in the water and use them for food. The water is then discarded through the top of their bodies, through their osculum.
Barrel sponges have no discernable harmful effects on the human body.
Since barrel sponges live latched onto the reef, it is not possible to have these marine creatures as pets.
Giant barrel sponges may filter as much water as 50,000 times the volume of its body!
It is possible for a giant barrel sponge to catch a disease known as 'sponge orange band', the cause of which remains unidentified. The oldest known giant barrel sponge (2300 years old) died from this disease.
The growth rate of a giant barrel sponge may be anywhere between 2% to 400%.
Giant barrel sponges are mostly asymmetrical, but some are radially symmetric.
The default barrel sponge worth in 'Animal Jam' is uncertain or unknown since their rarity changes a lot. It is also said that there is no actual value to the barrel sponge in 'AJ'.
Although some other sponge species live in freshwater bodies, barrel sponges mainly live in the marine waters of the Caribbean Sea.
Barrel sponges get their energy from the food particles they filter through their bodies, mainly phytoplankton and zooplankton. Hence, these sponges are known to be 'planktivores', which is the term used to describe organisms that feed on other microscopic or 'planktonic' organisms.
