Symbiotic ties, bioactive compounds, and mysterious distributions of bacteria characterize these ancient invertebrates ! Journal of Experimental Marine Biology and Ecology 473: 73-80. Symbiotic prokaryotic communities from different populations of the giant barrel sponge, Xestospongia muta. The giant barrel sponge is considered to be on the second trophic level, meaning that it is a primary consumer since it consumes photosynthetic cyanobacteria, which are primary producers (McMurray et al., 2008). The 5'-end fragment of the mitochondrial gene cytochrome oxidase subunit I is often used to address these kinds of questions, but it presents very low intraspecific nucleotide variability in sponges. Stegastes partitus. Pterois volitans. Search for more papers by this author. 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. Xestospongia muta increases habitat complexity and stability, and filters large volumes of water, enhancing water quality and facilitating nutrient cycling. Giant barrel sponge. 2014. On the reefs oV Key Largo, Seawater samples were collected from the incurrent and excurrent flow of 35 sponges. From 2000 to 2006, population densities of X. muta significantly increased at sites on Conch Reef by a mean of 46% (range = 16–108%) and on Pickles Reef by a mean of 33%. Ecological Archives E091-040-A1 Steven E. McMurray, Timothy P. Henkel, and Joseph R. Pawlik. Description. 1, is found abundantly in reef communities. Sponges take in water from the outside, which is funneled through small channels by rotating cilia.This is how they get their food. 2016. Selective feeding by the giant barrel sponge enhances foraging efficiency. Populations of this spe-cies occupy greater than 9% of the available reef substrate in some regions (Zea 1993). Microsatellite markers for the closely related Pacific giant … The giant barrel sponge Xestospongia muta a particularly important species; populations constitute a significant amount The giant barrel sponge, Xestospongia muta (Demo-spongiae: Haplosclerida) is a large and common member of Caribbean coral reef communities. Lionfish. The most common variably defended sponges were the giant barrel sponge Xestospongia muta and the green branched sponge Iotrochota birotulata. I knew they were sponges, but I hadn’t expected anything that large or abundant. These sponges also serve as a habitat for many other species such as other invertebrates, benthic fish, bacteria, and cyanobacteria. Video recorded with liquid image co camera mask filmed at 1080p. 2015, Journal of Experimental Marine Biology and Ecology. From 2000-2012, the density of the giant barrel sponge population increased by 44% on Pickles Reef, while on Conch Reef it more than doubled (fig 2)! This group of sponges are known to reach massive sizes and ages of 2000 years or more in warm Caribbean seas (Van Soest, 2012). A modest-sized giant barrel sponge can pump 15,000 litres per hour, giving a weekly volume roughly equal to that of an Olympic-sized swimming pool. doi: 10.1890/08-2060.1 pmid: … Contributions of transitions to the accelerated population decline of the giant barrel sponge, Xestospongia muta, from 2000-2003 to 2003-2006 on Conch Reef. The morphology and physiology of sponges were first adequately understood by who created in 1836 the name Porifera for the group by which it is now generally known, iuxle (1875) and Sollas (1884) proposed the complete separation of sponges from other Metazoa on the grounds of many peculiarities.

Diver collected cores of the giant barrel sponge, Xestospongia muta, for a population genetic analysis. Like reef-building corals, some sponges have been reported to bleach and die. This means that the increase in giant sponge density was in part due to the sponges growing and expanding, but also in part due to new recruits. Sponges with unknown chemical defense strategies comprised less than 1% of the total sponge assemblage.

Sponges with unknown chemical defense strategies comprised less than 1% of the total sponge assemblage. Hooper, Gert Wörheide, Dirk Erpenbeck Populations of the giant barrel sponge (Xestospongia muta), a common Caribbean species that can live for centuries (McMurray et al. The giant barrel sponge Xestospongia muta is one of the largest and most important components of Caribbean coral reef communities. Populations of X. muta that have been monitored annually in plots on Conch and Pickles Reefs in the Florida Keys increased by as much as 122% between 2000 and 2012, raising questions about the processes structuring these growing populations. The giant barrel sponges Xestospongia muta and Xestospongia testudinaria are ubiquitous in tropical reefs of the Atlantic and Pacific Oceans, respectively. Halimeda. spp. Population dynamics of giant barrel sponges on Florida coral reefs. Limnology and Oceanography 61 (4): 1271-1286. Mustard hill coral. Giant barrel sponges, Xestospongia muta, are known as the “redwoods of the reef” as they are large (can be up to ~6 feet in height and ~3 feet across), long-lived (> 2,000 years old), and provide habitat for many reef species. [Figure][1] Hospitable habitat. Giant barrel sponges may be affected by sponge orange band (SOB) disease; this is a disease specific to sponges, beginning with lesions on the pinacoderm and leading to bleaching that can be fatal within six weeks after infection. 2008) and grow to more than a meter in height and diameter (figure 1), have increased by 122% over the period 2000–2012 on Conch Reef in … the giant barrel sponge Xestospongia muta and the green branched sponge Iotrochota birotulata.

Sponges are a prominent component of coral reef ecosystems. Although (1816) separated the sponges in a group Spongiaria allied to Protozoa. We examined the carbon flux mediated by the giant barrel sponge, Xestospongia testudinaria, on reefs in the Red Sea across an inshore–offshore gradient that had previously been proposed to affect sponge nutrition in other parts of the tropics. McMurray SE, Pawlik JR, Finelli CM. Ecology 91 , 560 – 570 ( 2010 ). Cara L. Fiore. Tissues of X. muta contain cyanobacterial symbionts of the Synechococcus group. Redwoods of the reef: new insights on the giant barrel sponge of the Caribbean By Joseph R. Pawlik, Ph.D., Professor . Lettuce corals (Scleractinia; Agariciidae) Bicolor damselfish. The giant barrel sponge, Xestospongia muta, is prominent in many locations; on reefs off Key Largo, Florida, populations increased 46% over a six-year period beginning 2000. Red grouper . 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. assess the population genetic structure of sponges. The giant barrel sponge Xestospongia muta is a dominant member of Caribbean reef ecosystems. 2010. Giant barrel sponges, such as Xestospongia muta, are referred to by some as "Redwoods of the Reef." Symbiotic ties, bioactive compounds, and mysterious distributions of bacteria characterize these ancient invertebrates. Giant Barrel Sponges filter a tremendous amount of water throughout their lifespan (some living up to 2000 years) which increases water clarity, controls algae, and affects coral populations. They are key species in their respective environments and are hosts to diverse assemblages of bacteria. Sponges are an especially abundant and diverse group on Caribbean coral reefs that perform key community functions, however little is known about sponge demography. The oldest giant barrel sponge found off the coast of Venezuela and estimated to be 2300 years old died from SOB in only a few weeks. > Symbiotic ties, bioactive compounds, and mysterious distributions of bacteria characterize these ancient invertebrates !
