To improve understanding of the phylogenetic relationships within Demospongiae, we sequenced and analyzed seven nuclear housekeeping genes involved in a variety of cellular functions from a diverse group of sponges. Methodology/Principal Findings: We generated data from each of the four sponge classes (i.e., Calcarea, Demospongiae, Hexactinellida, and Homoscleromorpha), but focused on family-level relationships within demosponges. With data for 21 newly sampled families, our Maximum Likelihood and Bayesian-based approaches recovered previously phylogenetically defined taxa: Keratosap, Myxospongiaep, Spongillidap, Haploscleromorphap (the marine haplosclerids) and Democlaviap.We found conflicting results concerning the relationships of Keratosap and Myxospongiaep to the remaining demosponges, but our results strongly supported a clade of Haploscleromorphap+Spongillidap+Democlaviap. In contrast to hypotheses based on mitochondrial genome and ribosomal data, nuclear housekeeping gene data suggested that freshwater sponges (Spongillidap) are sister to Haploscleromorphap rather than part of Democlaviap. Within Keratosap, we found equivocal results as to the monophyly of Dictyoceratida. Within Myxospongiaep, Chondrosida and Verongida were monophyletic. A well- supported clade within Democlaviap, Tetractinellidap, composed of all sampled members of Astrophorina and Spirophorina (including the only lithistid in our analysis), was consistently revealed as the sister group to all other members of Democlaviap. Within Tetractinellidap, we did not recover monophyletic Astrophorina or Spirophorina. Our results also reaffirmed the monophyly of order Poecilosclerida (excluding Desmacellidae and Raspailiidae), and polyphyly of Hadromerida and Halichondrida. Conclusions/Significance: These results, using an independent nuclear gene set, confirmed many hypotheses based on ribosomal and/or mitochondrial genes, and they also identified clades with low statistical support or clades that conflicted with traditional morphological classification. Our results will serve as a basis for future exploration of these outstanding questions using more taxon- and gene-rich datasets.

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.

  • 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).

  • Revision of Rhabdastrella Distincta (Thiele, 1900)
    Revision of Rhabdastrella distincta (Thiele, 1900) A re-description of the holotype and description of two recently re-collected specimens Anne Twaalfhoven (10149996) Biology BSc Thesis, July 2016 University of Amsterdam: dr. P. (Peter) Roessingh, [email protected] Naturalis Biodiversity Center, Leiden: dr. N.J. (Nicole) de Voogd, [email protected] Abstract Sponge taxonomy is largely founded upon outdated descriptions originating from pre-modern times. Luckily, the material that these descriptions are based upon is often still available in Natural History Collections. In this article two sponge samples collected in 2009 from Ternate, Indonesia are compared to the type material of Rhabdastrella distincta. The holotype was described in 1896 by Thiele (1900). This article reviews the material for the first time ever since. The two recently collected samples are the first records of the species since its description. Descriptions of all three samples are based upon external morphology, skeletal structure, spicule measurements and spicule analysis by electron microscopy. It is revealed that, contrary to previous descriptions, the spherasters of R. distincta are stubbed with spines. Consequently, it is argued that the relation of R. distincta to its fellow species should be reconsidered. Euasters of R. distincta POR 5341 Twaalfhoven, July 2016, UvA Introduction When researching environmental change and biodiversity, Natural History Collections (NHC’s) can be of high value. Former taxonomists collected and described large collections of specimens that now serve as the foundation of our current knowledge on marine biodiversity (Jackson, 2001; Hooper & van Soest, 2002; Hoeksema et al, 2011). For reef systems, systematic ecological observations and methodological sampling started no earlier than the 1930’s (Jackson, 2001), and most recent surveys only encompass relatively short timespans (Jackson, 2001; van der Meij et al., 2010; Lister, 2011; Hoeksema et al., 2011).

  • Two Marine Sponges of the Family Ancorinidae (Demospongiae: Astroporida) from Korea
    Two Marine Sponges of the Family Ancorinidae (Demospongiae: Astroporida) from Korea Eun Jung Shim1,* Chung Ja Sim2 1Natural History Museum of Hannam University, Daejeon 306-791, Korea 2Department of Biological Sciences, College of Life Sciences and Nano Technology, Hannam University, Daejeon 305-811, Korea ABSTRACT Two sponges, Stelletta subtilis (Sollas, 1886) and Stryphnus sollasi n. sp., were collected from depth of 24-30 m at Jeju-do Island and Chuja-do Island by SCUBA diving from July 2003 to June 2010. The new species Stryphnus sollasi n. sp is similar with Stryphnus niger Sollas, 1886 in the composition of spicules, however they differ in colour and spicule size. This new species has smaller oxeas and larger oxyasters than those of S. niger. This new species has two size categories of oxyaster but S. niger has one size category of oxyaster. The colour of S. sollasi n. sp is white, but the latter puce black. Stelletta subtilis (Sollas, 1886) is first recorded in Korean fauna.

This family is characterized by the long-rhabdome triaenes and oxeas as megascleres and euasters, sanidasters or microrhabds as microscleres. The genus Stelletta is characterized by presence of long-shafted triaenes as megascleres and euasters without marked centrum as microscleres. Twelve Stelletta species have been reported in Korean waters so far (Shim and Sim, 2009).
