They also filter out food particles, which are transported into the non-living matrix (mesohyl). Flagellated choanocytes line the inner chamber and help generate water currents through the sponge. ![]() Water is taken into the inner chamber of the sponge (known as the spongocoel) through ostia (small pores created by porocytes). Their basic structure is typical of sponge species: a reticulation of cells aggregate on a siliceous scaffold composed of small spikes called spicules. Giant barrel sponges are called “redwoods of the reef” by some, because they may reach great sizes, over 1 m tall, with masses that exceed most other benthic invertebrates they are also extremely long lived. ( Bertin and Callahan, 2008 McMurray, et al., 2010 Shapiro, 2013) They have the highest density cover and greatest volume (0.2 individuals per m^2) of any organism living in their environment. They are benthic animals, living at depths from 10-30 m. ![]() Giant barrel sponges are members of coral reef environments in tropical coastal locations. ( López-Legentil and Pawlik, 2009 McMurray, et al., 2008 McMurray, et al., 2010 Montalvo and Hill, 2011 Richelle-Maurer, et al., 2003 van Soest, 2013) They are found as far south as Venezuela. They are found in highest concentrations in coral reefs off the coasts of Florida, in the Gulf of Florida, off the coast of Central America, and the Caribbean, including around the Bahamas and Greater Antilles. Giant barrel sponges are a marine species found in tropical areas of the Atlantic Ocean.
