To prevent other sponges from attacking them, Sponges can produce chemicals to keep other sponges cells from growing. Also known as Barrel-sponge Crab, Fairy Crab, Fairy Lobster, Hairy Pink Lobster, Hairy Pink Squat Lobster, Pink Hairy Squat Lobster, Pink Squat Lobster, Sponge Crab. Giant Barrel Sponge. This group of sponges are known to reach massive sizes and ages of 2000 years or more in warm Caribbean seas (Van Soest, 2012). The barrel sponges of the western Pacific, Indian Ocean, and the Caribbbean Sea are among the largest of all sponges. The genus is Xestospongia. The giant barrel sponge Xestospongia muta a particularly important species; populations constitute a significant amount of overall reef biomass, are an important component of habitat heterogeneity, and filter large amounts of seawater. Found around the giant barrel sponges - Xestospongia testudinaria over coral and rocky reefs. Despite the key role of sponges as structural components, habitat providers, and nutrient recyclers in reef ecosystems, their dispersal dynamics are little understood. Physical Features . Three species of giant barrel sponge are currently recognized in two distinct geographic regions, the tropical Atlantic and the Indo-Pacific. The Blue Barrel Sponge has the nickname "Redwood of the Reef" because of … 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. It can grow up to 35 feet and can stretch itself up to 6 feet wide. It is shaped like a barrel and thats where it gets its name from. It has been called the ‘redwood of the reef’ because of its size (often >1 m height and diameter) and presumed long life, but very little is known about its demography. Similar to all types of sponges, the barrel sponge filter feeds. [Figure] Hospitable habitat. Giant barrel sponges in the genus Xestospongia may be among the largest benthic invertebrates providing habitat and fulfilling ecosystem services on reefs where coral is declining. The Blue Barrel Sponges' tissues contains photosynthetic symbiotic cyanobacteria which gives it its color. Giant barrel sponges, such as Xestospongia muta, are referred to by some as "Redwoods of the Reef." The chemicals that a sponge produces are being used to find a cure for cancer and many other diseases! Sponge poop plays a key role in tropical reef ecosystems.

The bumpy surfaces of barrel sponges like this Giant Barrel Sponge (Xestospongia muta) provide habitat for a wide range of fishes and critters. Giant barrel sponge Xestospongia muta Giant barrel sponges are common inhabitants of coral reefs, especially in the Caribbean. Barrel shaped, with thick walls. The class is Demospongiae. Giant Barrel Sponge has shades of gray color, brown, red brown or rose purple color. We have monitored permanent plots on reefs off Key Largo, Florida, USA, to study the demography of a particularly important species, the giant barrel sponge, Xestospongia muta. Comparison of the mean ± 1 SD incurrent (ambient) availability and sponge‐mediated flux of C and DO for the giant barrel sponges X. testudinaria and X. muta. Illustration of the structure and anatomy of a typical sponge (barrel sponge, phylum porifera). 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. Symbiotic ties, bioactive compounds, and mysterious distributions of bacteria characterize these ancient invertebrates. They may be over 100 years old, as the sponges grow only about 1.5 cm a year. 1. It is also the largest species of sponge in the Caribbean. It is one of the biggest sponges in the world. about the demographics of sponges on coral reefs, despite their abundance and the important functions they perform (e.g., increased habitat complexity, water ﬁltration). 2. The giant barrel sponge Xestospongia muta dominates Caribbean coral reef communities, where it is an important spatial competitor, increases habitat complexity, and filters seawater. It’s habitat is on mid range to deep coral reefs and muddy sand bottoms in deeper water. The phylum is Porifera. 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. 415). This sponge was given its name due its hollow center and its round and open top, giving it a resemblance to a barrel. About the Giant Barrel Sponge The Giant Barrel Sponges are barrel-shaped sponges with a rough, hard exterior. Various critters can often be found resting inside these sponges. Some degraded reefs are characterized by high levels of sedimentation and low coral cover in this area, but support large populations of the ecologically important giant barrel sponge Xestospongia spp. Also known as Giant Barrel Sponge, Great Vase Sponge, Marine Sponge, Siliceous Sponge, Volcano Sponge. Giant specimens may reach a diameter of up to 2 meters. Length - 1.5cm Depth - 2-20m Widespread Indo-West Pacific A team of scientists led by Dr Lonny Lundsten of the Monterey Bay Aquarium Research Institute (MBARI) in Moss Landing, California, has discovered an extraordinary new species of carnivorous sponge. Surface with protuberances with round or blade-like outlines. Giant BArrel Sponge . Found singly or in small colonies over reef faces and flats of coral and rocky reefs. They feed on zooplankton. We are restoring the world’s wild fish populations to serve as a … 3. did you know that the Giant Barrel Sponge can live for over 2,000 years. Rumble / Unreal Animals — 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. Banded coral shrimps often make homes in vase sponges, like this (probable) Pink Vase (Niphates digitalis), Roatan, Honduras. > Symbiotic ties, bioactive compounds, and mysterious distributions of bacteria characterize these ancient invertebrates ! Small fish and many invertebrates live on and inside these huge animals, which live on tropical coral reefs. Resolving the genetic connectivity of coral reef taxa is necessary to understand the community dynamics of these increasingly threatened ecosystems. Their hollow bodies can grow to around 2m (6.5ft) tall and 2m (6.5ft) wide, large enough to hold an adult human. Top Facts About Sponges. It can also have several different shaped openings.
