Sponge on a Coral Reef. But those are educated guesses rather than proven observations. The Azure Vase sponge have flagella which line their pores and aid the passage of water through the sponge’s water flow systems. The vase sponge is characterized by a large bell shape with a deep central cavity. Eucidaris tribuloides, the slate pencil urchin, is a cidaroid sea urchin that inhabits littoral regions of the Atlantic Ocean. The giant barrel sponge Xestospongia muta is a dominant member of Caribbean reef ecosystems. Subse- It is. We quantified suspension feeding by the giant barrel sponge Xestospongia muta on Conch Reef, Florida, to examine relationships between diet choice, food resource availability, and foraging efficiency. The phylum is aptly named. From the University of Michigan Museum of Zoology: Giant barrel sponges play an important role in coral reef ecosystems because they filter large quantity of water and provide habitat for other organisms. After the turtle lays on top it will build up pressure in the sponge that will eventually break the seal and push the turtle upwards towards the surface. Front Microbiol. The finger sponge is a sponge with finger-shaped lobes, or branches. The last two images were kindly provided by Armin Svoboda (Ruhr-Universität, Bochum, Germany). The giant barrel sponge, Xestospongia muta, is an abundant and long-lived sponge on Caribbean coral reefs that is actively grazed by sponge-eating fishes and is susceptible to disease. One of the world's most colorful sponges being any color from purple to pink to blue. Tube, barrel, and finger sponges have vertical morphologies. 415). Microorganisms may even help defend their hosts against disease-causing bacteria. This orange sponge is covered with pores. Surface with protuberances with round or blade-like outlines. The sponge takes in water at the bottom and then ejects it from the osculum which is the “mouth” at the top of the sponge. Additionally, sponges consume dissolved organic carbon (DOC) and detritus, but relative preferences for these resources are unknown. Joseph Richard Pawlik is a marine biologist.He is the Frank Hawkins Kenan Distinguished Professor of Marine Biology in the Department of Biology and Marine Biology at the University of North Carolina Wilmington.He is best known for studies of sponges on … Some common Caribbean sponges, such as the chicken liver sponge Chondrilla caribensis, the giant barrel sponge Xestospongia muta, and the pink vase sponge Niphates digitalis, exhibit an exaggerated form of this pattern, where even within the same population, individuals will vary dramatically in their levels of chemical defense [35–37]. Fiore CL, Labrie M, Jarett JK, Lesser MP. Giant Barrel Sponge at two reef sites off the coast of Key Largo, Florida, since 1997. Transcriptional activity of the giant barrel sponge, Xestospongia muta Holobiont: molecular evidence for metabolic interchange. It is called the Azure "vase" due to it's shape. ... including defense against predators … The sponge can control water flow by closing partially or entirely the osculum. The giant barrel sponge, Xestospongia muta, is an abundant and long-lived sponge on Caribbean coral reefs that is actively grazed by sponge-eating fishes and is susceptible to disease. For the giant barrel sponge X. muta, which is a net consumer of detritus (McMurray et al., 2016), DOC consumption alone accounts for 60–100% of respiratory demands, with the balance of organic carbon acquired likely allocated to sponge growth (Hoer et al., 2018). Oscules on the inner side of vase; 0.2 - 0.3 cm (Ref. Mean density of the giant barrel sponge, Xestospongia muta, at different depths at sites on Conch and Pickles Reefs, Key Largo, Florida, USA, from May 2000 to November 2006. They can mostly be found in South Florida, the Bahamas, and in the Carribean. Synalpheus longicarpus (Longclawed sponge shrimp) Contents. The giant barrel sponge Xestospongia muta is a dominant component of Caribbean coral reef communities, ... 2004) and unpalatable to fish predators (Lindquist and Hay, 1996), and larval dispersal is influenced by ocean currents (López-Legentil and Pawlik, 2008).  The Digestive System of a Kinabalu Giant Red Leech (Mimobdella buettikoferi The digestive system of a leech consists of four parts, and is located on the upper side of its body, apart from the mouth. As a member of the basal echinoid order Cidaroida, its morphological, developmental and molecular genetic characteristics make it a phylogenetically interesting species. Additionally, long-term population studies on the giant barrel sponge Xestospongia muta, a sponge that exhibits highly variable chemical defenses , showed that sponge densities increased 2–5 times faster at 30 m compared to 10 m and 20 m, while sponge size frequency distributions shifted to smaller sponge sizes across all depths at Conch Reef . The Azure Vase Sponge lives in coral reefs and commonly grows on walls. Email: leonny.hartiadi@i3l.ac.id ABSTRACT Chemical defenses are known to protect some species from consumers, but it is often difficult to detect this advantage at the community or ecosystem levels because of the complexity of abiotic and biotic factors that influence species abundances. The sheer mass of the microbes may help support the meter-high giant barrel sponge Xestospongia muta , in which bacteria can sometimes make up 40% of a sponge's volume.
