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. -

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.

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). -

EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). -
Estimates of Sponge Consumption Rates on an Indo-Pacific Reef
Vol. 672: 123–140, 2021 MARINE ECOLOGY PROGRESS SERIES Published August 19 https://doi.org/10.3354/meps13786 Mar Ecol Prog Ser Estimates of sponge consumption rates on an Indo-Pacific reef Charlotte Mortimer1, Matthew Dunn2, Abdul Haris3, Jamaluddin Jompa3, James Bell1,* 1School of Biological Sciences, Victoria University of Wellington, Wellington 6012, New Zealand 2The National Institute of Water and Atmospheric Research (NIWA), Wellington 6021, New Zealand 3Universitas Hasanuddin, Department of Marine Science, Makassar 90245, Indonesia ABSTRACT: Determining predator diets is essential for understanding the strength of top-down processes and how they cascade through food webs. This is especially important for sponges, key members of benthic communities, whose dominance has increased in recent years on some coral reefs. However, the diversity of spongivorous fishes and the sponges they consume are relatively unknown. Here, we estimated sponge consumption by spongivorous fishes in the Wakatobi Marine National Park, Indonesia. We deployed cameras to identify fish biting at the dominant reef sponge Xestospongia spp. and then used gut content analysis and fish abundance estimates to quantify sponge consumption. In total, 33 species from 10 families of reef fish were identified taking bites from Xestospongia spp.; however, the 2 most prolific sponge-grazers, Ctenochaetus binotatus and Chaetodon kleinii, had no sponge in their guts, showing that for some fish, bites on sponge surfaces are not reliable evidence of sponge consumption. Gut contents indicated that Pygoplites diacanthus was an obligate spongivore, while Pomacanthus imperator, P. xanthometo- pon, Zanclus cornutus and Siganus punctatus regularly consumed sponges. Sponge consumption by these 5 spongivores was estimated at 46.6 ± 18.3 g sponge 1000 m−2 d−1. -
Supplementary Materials: Patterns of Sponge Biodiversity in the Pilbara, Northwestern Australia

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. -

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. -
