Xestospongia testudinaria is a species of barrel sponge in the family Petrosiidae.More commonly known as Giant Barrel Sponges, they have the basic structure of a typical sponge. Reaching sizes of at least 6 feet (1.8 m) across, this is one of the largest sponge species wherever it lives. Having no digestive tract, localized sensory region, or true tissues, they are little more than a cluster of cells supported by a structure of spongin and spicules.Spongin is the flexible material that makes up the body wall of the sponge… The stovepipe sponges have a tubular body and they grow up to 150 cm in length. The genus is Xestospongia. Members of this group include glass sponges, demosponges, and calcareous sponges. Like other sponges, the Strawberry Vase Sponge eats by trapping microscopic plankton from the ocean as it pumps seawater through its body. The sponge is covered with pores where the algea is sucked in. Create your own unique website with customizable templates.

The Strawberry Vase Sponge is permanently attached to the coral head on which it is growing. The sponges harbored a variety of phylum level operational taxonomic units (OTUs) ... was to understand and characterize the taxonomic variability of the prokaryotic community of the ecologically dominant giant barrel sponge, Xestospongia muta, (McMurray et al. The giant barrel sponge Xestospongia muta dominates Caribbean coral reef communities, where it is an important spatial competitor, increases habitat complexity, and filters seawater. The Strawberry Vase Sponge is permanently attached to the. ... sponge too has no circulatory system like its other relatives in this phylum. In this study, we used molecular techniques to study populations of giant barrel sponges across the globe and assessed whether the genetic structure of these populations agreed … Phylum Group #3 > > > Giant Barrel Sponge. The sample with the lowest relative contribution of its core community (38.8%) was a sponge from Taiwan (Tw4s476) and the sample with the highest relative … Giant Barrel Sponge Giant Barrel sponge (Xestospongia muta) is the largest species of sponge found growing on Carribean coral reefs. The class is Demospongiae. The domain is Eukarya. Giant barrel sponge. Cyclical bleaching affects about 25% of giant barrel sponges and recovery is possible over time; fatal bleaching affects only about 1% of giant barrel sponges. One of the largest species of sponge found in the Caribbean. Symbiotic prokaryotic communities from different populations of the giant barrel sponge, Xestospongia muta. There is little scientific information about the species. Sponges have no real circulatory system.Sponges have flagellated cells over the surface of their bodies, these are cells that have tails that wiggles. This has the same sort of "circulatory" water based system as mentioned aboce. They are aquatic organisms classified under the phylum Porifera with about 15,000 species worldwide. The Giant Barrel sponge (Also known as Xestospongia muta) is one of the largest species of sponge found mainly in the Caribbean.

Porifera are sessile creatures, which means they do not move and are attached directly by its base without a stalk. Common sponges from shallow marine habitats from Bocas del Toro region, Panama.

The barrel sponge is usually found in the colors red, brown, gray, and purple. They are key species in their respective environments and are hosts to diverse assemblages of bacteria. The growth of animals in most taxa has long been well described, but the phylum Porifera has remained a notable exception. Porifera Phylum. The family is Petrosiidae. X. Three species of giant barrel sponge are currently recognized in two distinct geographic regions, the tropical Atlantic and the Indo-Pacific. Their body is made of a reticulation of cells aggregate on a siliceous scaffold composed of small spikes called spicules. There are several different types of sponges: encrusting sponges, boring sponges, coralline sponges, bath sponges, and medical sponges. The word "porifera" means pore-bearing.
