The Giant Barrel Sponge is a filter feeder, which means that it feeds on particles collected by pumping water through its body. There are several choanocytes or flagellated cells that line the internal cavity of the sponge. These cells filter the incoming food particles, particularly microscopic bacteria.

How long can a barrel sponge live?
Giant tube sponges can live as long as 2000 years (and probably much longer). The conservation status of the giant tube sponge is unknown. However, because this species lives mostly on coral reefs, changes to that fragile system caused by irresponsible human behavior may threaten this sponge.
How old are barrel sponges?
The oldest giant barrel sponge measured in the study was estimated to be 127 years old. The team also estimated, from a photograph, that a giant barrel sponge discovered off of the Caribbean island of Curacao in 1997 was about 2,300 years old.
Where are barrel sponges found?
Giant barrel sponges (Xestospongia muta) are the largest sponges found in the Caribbean and the Gulf of Mexico, most commonly on coral reefs. Their large size and incredibly long lifespan earned them the nickname, “redwood of the reef”.
What does a barrel sponge look like?
Description. The giant barrel sponge is variable in form. It is very large and firm, typically being barrel-shaped, with a cone-shaped cavity at the apex known as the osculum. However, some individuals within the same population may be low and squat or relatively tall and thin.
What do barrel sponges eat?
The Giant Barrel Sponge is a filter feeder, which means that it feeds on particles collected by pumping water through its body. There are several choanocytes or flagellated cells that line the internal cavity of the sponge. These cells filter the incoming food particles, particularly microscopic bacteria.
What is the largest sponge in the world?
A sponge the size of a minivan, the largest on record, was found last summer during a deep-sea expedition in Papahānaumokuākea Marine National Monument. Today, Marine Biodiversity published a study describing the 12 foot by 7 foot sponge that was found at depth of 7,000 feet.
Does a sponge eat?
So how do sponges eat? Sponges are mostly filter feeders and they eat detritus, plankton, viruses and bacteria. They also absorb dissolved nutrients directly from the water through their pinacocyte cells; each cell is responsible for getting their own food!
What is unique about the barrel sponge?
The giant barrel sponge is a large sponge that lives on coral reefs around the Caribbean Sea and adjacent waters. Reaching sizes of at least 6 feet (1.8 m) across, this is one of the largest sponge species wherever it lives. ... Like most sponges, this species has a glass-like skeleton.
How does the barrel sponge defend itself?
Anti-predator behaviour: The presence of spicules (small mineral spines) is a form of physical defence against predation in many sponges. ... It has also been found that the giant barrel sponge showed variable results in its ability to chemically defend itself (Waddell and Pawlik, 2000).
Can coral be black?
Black corals are rarely black, but rather vary in color from white to red, green, yellow, or brown. They also range in shape from small bushes to bottle brushes to fans to single stalks. The black corals differ greatly from stony corals in terms of their skeletons.
What eats sponges in the coral reef?
One of the main weapons in sponges' arsenal to compete on the crowded coral reef is that they are very toxic. Very few species of large angelfish, sea turtles and nudibranch have evolved to consume primarily sponges.
How big can sponges grow?
There is great variability in their size: some sponges are very small (just a few centimeters) while others are very big, like the giant barrel sponge, which can be six feet wide.
Is coral a reef?
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas.
Why are sponges considered animals?
Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. ... All sponges are sessile aquatic animals, meaning that they attach to an underwater surface and remain fixed in place (i.e., do not travel).
Which is the smallest sponge?
Leucosolenia - smallest sponge.
