Distinguishing Characteristics of Sponges
Distinguishing characteristics of sponges Continue Sponges are amazing creatures with some unique characteristics. Here is a brief overview of sponges and their features. You are here: Home / Uncategorized / Characteristics of sponges: BTW, They are animals, NOT plants! Sponges are amazing creatures with some unique characteristics. Here is a brief overview of sponges and their features. Almost all of us are familiar with commercial sponges, which are used for various purposes, such as cleaning. There are several living sponges found in both seawater as well as fresh water. These living species are not plants, but are classified as porifera animals. The name of this branch is derived from the pores on the body of the sponge, and it means the bearer of pores in Greek. It is believed that there are about 5000 to 10,000 species of sponges, and most of them are found in seawater. So sponges are unique aquatic animals with some interesting characteristics. Would you like to write to us? Well, we are looking for good writers who want to spread the word. Get in touch with us and we'll talk... Let's work together! Sponges are mainly found as part of marine life; but, about 100 to 150 species can be found in fresh water. They may resemble plants, but are actually sessile animals (inability to move). Sponges are often found attached to rocks and coral reefs. You can find them in different forms. While some of them are tube-like and straight, some others have a fan-like body. Some are found as crusts on rocks. -
Effects of Ocean Acidification on Sponge Communities
Marine Ecology. ISSN 0173-9565 ORIGINAL ARTICLE Effects of ocean acidification on sponge communities Claire Goodwin1, Riccardo Rodolfo-Metalpa2, Bernard Picton1 & Jason M. Hall-Spencer2 1 National Museums Northern Ireland, Holywood, County Down, UK 2 Marine Biology and Ecology Research Centre, Plymouth University, Plymouth, UK Keywords Abstract CO2 vents; Mediterranean; ocean acidification; Porifera; sponge; volcanic vents. The effects of ocean acidification on lower invertebrates such as sponges may be pronounced because of their low capacity for acid–base regulation. However, so Correspondence far, most studies have focused on calcifiers. We present the first study of the Claire Goodwin, National Museums Northern effects of ocean acidification on the Porifera. Sponge species composition and Ireland, 153 Bangor Road, Cultra, Holywood, cover along pH gradients at CO2 vents off Ischia (Tyrrhenian Sea, Italy) was County Down BT20 5QZ, UK. measured at sites with normal pH (8.1–8.2), lowered pH (mean 7.8–7.9, min E-mail: [email protected] 7.4–7.5) and extremely low pH (6.6). There was a strong correlation between pH Accepted: 4 July 2013 and both sponge cover and species composition. Crambe crambe was the only species present in any abundance in the areas with mean pH 6.6, seven species doi: 10.1111/maec.12093 were present at mean pH 7.8–7.9 and four species (Phorbas tenacior, Petrosia fici- formis, Chondrilla nucula and Hemimycale columella) were restricted to sites with normal pH. Sponge percentage cover decreased significantly from normal to acidified sites. No significant effect of increasing CO2 levels and decreasing pH was found on spicule form in Crambe crambe. -

P. Payne MSc Thesis, Department of Biodiversity and Conservation Biology, University of the Western Cape. Seamounts are poorly understood ubiquitous undersea features, with less than 4% sampled for scientific purposes globally. Consequently, the fauna associated with seamounts in the Indian Ocean remains largely unknown, with less than 300 species recorded. One such feature within this region is Walters Shoal, a shallow seamount located on the South Madagascar Ridge, which is situated approximately 400 nautical miles south of Madagascar and 600 nautical miles east of South Africa. Even though it penetrates the euphotic zone (summit is 15 m below the sea surface) and is protected by the Southern Indian Ocean Deep- Sea Fishers Association, there is a paucity of biodiversity and oceanographic data. -

Although an aristo land), of botany and zoology in Gent (Belgium), and crat by birth, as we learn from Michelotti's last extant then of zoology and geology in Leyden. Later he went to letter to van Breda, Duchassaing did not add de Fon Haarlem, where he was secretary of the Hollandsche bressin to his name until 1864. Duchassaing was born Maatschappij der Wetenschappen, curator of its cabinet around 1819 on Guadeloupe, in a French-Creole family of natural history, and director of Teyler's Museum of of planters. He was sent to school in Paris, first to the minerals, fossils and physical instruments. Van Breda Lycee Louis-le-Grand, then to University. He finished traveled extensively in Europe collecting fossils, especial his studies in 1844 with a doctorate in medicine and two ly in Italy. Michelotti exchanged collections of fossils additional theses in geology and zoology. He then settled with him over a long period of time, and was received as on Guadeloupe as physician. Because of social unrest foreign member of the Hollandsche Maatschappij der after the freeing of native labor, he left Guadeloupe W etenschappen in 1842.

Proposal for a Revised Classification of the Demospongiae (Porifera) Christine Morrow1 and Paco Cárdenas2,3*
Morrow and Cárdenas Frontiers in Zoology (2015) 12:7 DOI 10.1186/s12983-015-0099-8 DEBATE Open Access Proposal for a revised classification of the Demospongiae (Porifera) Christine Morrow1 and Paco Cárdenas2,3* Abstract Background: Demospongiae is the largest sponge class including 81% of all living sponges with nearly 7,000 species worldwide. Systema Porifera (2002) was the result of a large international collaboration to update the Demospongiae higher taxa classification, essentially based on morphological data. Since then, an increasing number of molecular phylogenetic studies have considerably shaken this taxonomic framework, with numerous polyphyletic groups revealed or confirmed and new clades discovered. And yet, despite a few taxonomical changes, the overall framework of the Systema Porifera classification still stands and is used as it is by the scientific community. This has led to a widening phylogeny/classification gap which creates biases and inconsistencies for the many end-users of this classification and ultimately impedes our understanding of today’s marine ecosystems and evolutionary processes. In an attempt to bridge this phylogeny/classification gap, we propose to officially revise the higher taxa Demospongiae classification. Discussion: We propose a revision of the Demospongiae higher taxa classification, essentially based on molecular data of the last ten years. We recommend the use of three subclasses: Verongimorpha, Keratosa and Heteroscleromorpha. We retain seven (Agelasida, Chondrosiida, Dendroceratida, Dictyoceratida, Haplosclerida, Poecilosclerida, Verongiida) of the 13 orders from Systema Porifera. We recommend the abandonment of five order names (Hadromerida, Halichondrida, Halisarcida, lithistids, Verticillitida) and resurrect or upgrade six order names (Axinellida, Merliida, Spongillida, Sphaerocladina, Suberitida, Tetractinellida). Finally, we create seven new orders (Bubarida, Desmacellida, Polymastiida, Scopalinida, Clionaida, Tethyida, Trachycladida). -
Supplementary Materials: Patterns of Sponge Biodiversity in the Pilbara, Northwestern Australia
Diversity 2016, 8, 21; doi:10.3390/d8040021 S1 of S3 9 Supplementary Materials: Patterns of Sponge Biodiversity in the Pilbara, Northwestern Australia Jane Fromont, Muhammad Azmi Abdul Wahab, Oliver Gomez, Merrick Ekins, Monique Grol and John Norman Ashby Hooper 1. Materials and Methods 1.1. Collation of Sponge Occurrence Data Data of sponge occurrences were collated from databases of the Western Australian Museum (WAM) and Atlas of Living Australia (ALA) [1]. Pilbara sponge data on ALA had been captured in a northern Australian sponge report [2], but with the WAM data, provides a far more comprehensive dataset, in both geographic and taxonomic composition of sponges. Quality control procedures were undertaken to remove obvious duplicate records and those with insufficient or ambiguous species data. Due to differing naming conventions of OTUs by institutions contributing to the two databases and the lack of resources for physical comparison of all OTU specimens, a maximum error of ± 13.5% total species counts was determined for the dataset, to account for potentially unique (differently named OTUs are unique) or overlapping OTUs (differently named OTUs are the same) (157 potential instances identified out of 1164 total OTUs). The amalgamation of these two databases produced a complete occurrence dataset (presence/absence) of all currently described sponge species and OTUs from the region (see Table S1). The dataset follows the new taxonomic classification proposed by [3] and implemented by [4]. The latter source was used to confirm present validities and taxon authorities for known species names. The dataset consists of records identified as (1) described (Linnean) species, (2) records with “cf.” in front of species names which indicates the specimens have some characters of a described species but also differences, which require comparisons with type material, and (3) records as “operational taxonomy units” (OTUs) which are considered to be unique species although further assessments are required to establish their taxonomic status. -
Incidence and Identity of Photosynthetic Symbionts in Caribbean Coral Reef Sponge Assemblages

(2007), 87, 1683-1692 doi: 10.1017/S0025315407058213 Printed in the United Kingdom Incidence and identity of photosynthetic symbionts in Caribbean coral reef sponge assemblages Patrick M. Erwin and Robert W. Thacker* University of Alabama at Birmingham, 109 Campbell Hall, 1300 University Boulevard, Birmingham, Alabama 35294-1170, USA. Corresponding author, e-mail: [email protected] Marine sponges are abundant and diverse components of coral reefs and commonly harbour photosynthetic symbionts in these environments. The most prevalent symbiont is the cyanobacterium, Synechococcus spongiarum, isolated from taxonomically diverse hosts from geographically distant regions. We combined analyses of chlorophyll-a (chl-a) concentrations with line-intercept transect surveys to assess the abundance and diversity of reef sponges hosting photosymbionts on Caribbean coral reefs in the Bocas del Toro Archipelago, Panama. To identify symbionts, we designed PCR primers that specifically amplify a fragment of the 16S ribosomal RNA gene from S. spongiarum and used these primers to screen potential host sponges for the presence of this symbiont. Chlorophyll-a data divided the sponge community into two disparate groups, species with high (>125 Mg/g, N=20) and low (<50 Mg/g, N=38) chl-a concentrations. Only two species exhibited intermediate (50— 125 (Jg/g) chl-a concentrations; these species represented hosts with reduced symbiont populations, including bleached Xestospongia muta and the mangrove form of Chondrilla nucula (C. nucula f. hermatypicd). Sponges with high and intermediate chl-a concentrations accounted for over one-third of the species diversity and abundance of sponges in these communities. Most (85%) of these sponges harboured S. -
General Introduction and Objectives 3
General introduction and objectives 3 General introduction: General body organization: The phylum Porifera is commonly referred to as sponges. The phylum, that comprises more than 6,000 species, is divided into three classes: Calcarea, Hexactinellida and Demospongiae. The latter class contains more than 85% of the living species. They are predominantly marine, with the notable exception of the family Spongillidae, an extant group of freshwater demosponges whose fossil record begins in the Cretaceous. Sponges are ubiquitous benthic creatures, found at all latitudes beneath the world's oceans, and from the intertidal to the deep-sea. Sponges are considered as the most basal phylum of metazoans, since most of their features appear to be primitive, and it is widely accepted that multicellular animals consist of a monophyletic group (Zrzavy et al. 1998). Poriferans appear to be diploblastic (Leys 2004; Maldonado 2004), although the two cellular sheets are difficult to homologise with those of the rest of metazoans. They are sessile animals, though it has been shown that some are able to move slowly (up to 4 mm per day) within aquaria (e.g., Bond and Harris 1988; Maldonado and Uriz 1999). They lack organs, possessing cells that develop great number of functions. The sponge body is lined by a pseudoepithelial layer of flat cells (exopinacocytes). Anatomically and physiologically, tissues of most sponges (but carnivorous sponges) are organized around an aquiferous system of excurrent and incurrent canals (Rupert and Barnes 1995). These canals are lined by a pseudoepithelial layer of flat cells (endopinacocytes).Water flows into the sponge body through multiple apertures (ostia) General introduction and objectives 4 to the incurrent canals which end in the choanocyte chambers (Fig. -
