It is also the largest species of sponge in the Caribbean. For the Giant Barrel Sponge, the way it retrieves food is very similar to that of a sponge, however instead of the many pores a sponge holds the barrel sponge uses the main hole as a way to live. They are impressive in their size and their presence in the underwater world, but the facts about them and their importance to the health of the reef and the ocean is truly surprising. 2. They feed on zooplankton. That is longer than you can live! Sponges can cotain 16,000 other animals inside of it. They can be gray, brown, red-brown or rose-purple. Retrieving food via the water that flows through the main pore of the sponge. They are impressive in their size and their presence in the underwater world, but the facts about them and their importance to the health of the reef and the ocean is truly surprising. Giant barrel sponges are actually animals, despite the fact that they grow fixed to the reef or the ocean bottom, giving us the impression that they are plants. Resolving the genetic connectivity of coral reef taxa is necessary to understand the community dynamics of these increasingly threatened ecosystems. Incurrent C and DO concentrations are reported as μmol C L seawater −1 and μmol O 2 L seawater −1 , respectively. Giant Barrel Sponge. Various critters can often be found resting inside these sponges. It is shaped like a barrel and thats where it gets its name from. Barrel shaped, with thick walls. The domain is Eukarya. It is one of the biggest sponges in the world. We are restoring the world’s wild fish populations to serve as a … 3. Illustration of a giant barrel sponge (Xestospongia muta) used in a life history poster. Populations of the giant barrel sponge (Xestospongia muta) increased by 46% over six years, beginning in 2000, on reefs off the Florida Keys (McMurray et al. Length - 1.5m Depth - … Giant specimens may reach a diameter of up to 2 meters. It’s habitat is on mid range to deep coral reefs and muddy sand bottoms in deeper water. It is the largest of the reef-dwelling invertebrate in these areas. Symbiotic ties, bioactive compounds, and mysterious distributions of bacteria characterize these ancient invertebrates. The family is Petrosiidae. Not only are they the largest sponges on the reef, but they also are very long lived – up tp thousands of years. 4. The Blue Barrel Sponge provides a habitat for various invertebrates. about the demographics of sponges on coral reefs, despite their abundance and the important functions they perform (e.g., increased habitat complexity, water ﬁltration). The largest species of sponge (Porifera) is the giant barrel sponge (Xestospongia muta).It grows at depths from 10 m (33 ft) down to 120 m (390 ft), and can reach a diameter of 1,8 – 2 m (6 – 6,6 ft). Giant Barrel Sponge. Brittle and crumbly in consistency. Herein, we assess the fine scale genetic connectivity of six populations of the Atlantic giant barrel sponge, Xestospongia muta (Schmidt, 1870), using It can also have several different shaped openings. Small fish and many invertebrates live on and inside these huge animals, which live on tropical coral reefs.

The bumpy surfaces of barrel sponges like this Giant Barrel Sponge (Xestospongia muta) provide habitat for a wide range of fishes and critters. 1. Illustration of the structure and anatomy of a typical sponge (barrel sponge, phylum porifera). The chemicals that a sponge produces are being used to find a cure for cancer and many other diseases! did you know that the Giant Barrel Sponge can live for over 2,000 years. This sponge was given its name due its hollow center and its round and open top, giving it a resemblance to a barrel. The Giant Barrel Sponge can be found in the Caribbean sea, the Bahamas, Bermuda, and in reefs around Florida. Also known as Giant Barrel Sponge, Great Vase Sponge, Marine Sponge, Siliceous Sponge, Volcano Sponge. Like most sponges, they pump water through their bodies to obtain food: plankton, bacteria and nutrients from the seawater.
