A monograph of the shallow-water Chalinidae (Porifera, Haplosclerida) of the Caribbean Naturalis
Weerdt, Wallie H. de.
All known species of the sponge family Chalinidae (Demospongiae, Haplosclerida) occurring in the shallower part of the Caribbean are described and taxonomically revised. The study is the result of collecting activities of the author and others throughout the Caribbean, and examination of type and other material in musea and institutes. In a previous revision of north-eastern Atlantic Chalinidae (De Weerdt, 1986, 1989), the family was subdivided into eight monophyletic species groups, with various states of the skeletal architecture as main synapomorphous (shared derived) characters. After examination of all available type species of the nominal genera of the family, the species groups are now given proper names, replacing the tentative names in the earlier...

A new Agelas (Demospongiae: Agelasida: Agelasidae) from the Thousands Islands, West-Java, Indonesia Naturalis
Voogd, N.J. de; Parra-Velandia, F.J.; Soest, R.W.M. van.
Agelas linnaei spec.nov. (Porifera: Demospongiae: Agelasida: Agelasidae) is described from the Thousands Islands reef complex, West- Java, Indonesia. The new species is compared with all other Agelas species occurring in the Indo-West Pacific region. The new species differs from these other species by the overall morphology and the size of the verticillated acanthostyles. Surprisingly, this is only the second Agelas species ever described from Indonesia.

A new species oc Cladocroce Topsent, 1892 (Porifera, Haplosclerida) from the Gulf of Thailand Naturalis
Putchakarn, Sumaitt; Weerdt, Wallie H. de; Soncheang, Pichai; Soest, Rob W.M. van.
A new sponge species, Cladocroce burapha n. sp. (Chalinidae, Haplosclerida, Porifera), is described from Chonburi province, eastern coast of the Gulf of Thailand, Thailand. The new species can be separated from other Cladocroce species by a combination of characters, including growth form, form and size of the spicules, and habitat. This is the first record of the genus Cladocroce from Thailand.

A new species of Biemna (Porifera, Poecilosclerida) from the Sultanate of Oman Naturalis
Soest, R.W.M. van; Beglinger, E.J..
Recent (1998) collecting off the coasts of Oman in the course of the EC-MAS3 funded ‘Symbiosponge’ project yielded three species of the genus Biemna Gray, 1867 (Demospongiae, Poecilosclerida, Mycalina, Desmacellidae) not previously known from the area. One of these appeared to be new to science and is described as Biemna omanensis n.sp.. Its distinguishing features comprise the possession of oxea megascleres, which is of rare occurrence in Biemna, and a full complement of microscleres including microxeas, sigmas, commata, all of which are divisible in two non-overlapping size categories, and raphides. One of the other two species conformed to an earlier described species Biemna ciocalyptoides Burton, 1959, which was discovered to be a junior synonym of...

A new species of Erylus Gray, 1867 (Porifera, Geodiidae) from the southeastern coast of Brazil Naturalis
Mothes, Beatriz; Lerner, Cléa.
A new species, Erylus soesti n. sp. is described from SE Brazil. This study is part of an ongoing revision of genus Erylus Gray, 1867 (Mothes, Lerner & Da Silva, 1999; Mothes & Lerner, 1999) and adds a further brazilian species to the genus. This new species can be distinguished by the possession of dichotriaenes, oxeas, and peculiar cushion-like aspidasters with extremely irregular outline, microspined microstrongyles and sphaeroxyasters. A key for identification of brazilian species is provided.

A new sponge Desmapsamma vervoorti spec. nov. (Poecilosclerida: Desmacididae) from Indonesia Naturalis
Soest, R.W.M. van.
A new poecilosclerid sponge species Desmapsamma vervoorti spec. nov. is described from several Indonesian localities: Ambon, Jedan, Salayar, Komodo, Java, and Irian Jaya. The species was earlier reported from several Indo-Pacific localities as D. anchorata (Carter, 1882), a common Caribbean shallow water species. Comparison with Caribbean specimens makes it clear that Indo-Pacific specimens demonstrate small but consistent differences.

A new Suberites (Demospongiae: Hadromerida: Suberitidae) from the tropical Indo-West Pacific Naturalis
Becking, L.E.; Lim, S.C..
In this paper we describe Suberites diversicolor spec. nov. (Porifera: Demospongiae: Hadromerida: Suberitidae) from four enclosed anchialine lakes located in Indonesia and from a confined system in Singapore. Initially this species was thought to be specific to anchialine lakes, but further comparison to coastal areas indicated that it is more widespread in inshore systems. We have used morphological characters to distinguish this species and a molecular marker to confirm that all types are the same species. Suberites diversicolor spec. nov. is encrusting or massive with small protrusions or larger globular branches. The external colour can be olive-green, blue, purple, red-orange, or orange-yellow. Suberites diversicolor spec. nov. differs from known...

A remarkable new Middle Sandbian (Ordovician) hexactinellid sponge in Baltic erratics Naturalis
Botting, J.P.; Rhebergen, F..
A new species of complex hexactinellid sponge, Haljalaspongia inaudita, is described from fluvially transported blocks found in northwestern Germany, near the Dutch border, but which probably originated from the eastern Baltic region. The heavily folded wall is composed of multiple spicule layers, including dermal and gastral layers of acanthohexactines, and a central layer of sub-parallel monaxons. The monaxial layer is lined on one side by a reticulate array of smooth monaxons. The sponge is difficult to assign to any known fossil or recent group, but shares some features with the dictyospongioid family Docodermatidae.

Amphimedon denhartogi spec. nov. (Porifera: Haplosclerida) from deep reef habitats in Indonesia Naturalis
Voogd, N.J. de.
A new sponge species Amphimedon denhartogi spec. nov., belonging to the family Niphatidae of the order Haplosclerida, is described from 3 localities in Indonesia: Tulamben (NE Bali), Siladen Island (NE Sulawesi) and Kambing Island (SW Sulawesi). Amphimedon denhartogi spec. nov. is characterised by its growth form of thinly flabellate branches, the occurrence of star-shaped oscules over one side of the sponge body, and by its small strongyles, and can hardly be confused with another species. All specimens were found in similar habitats, at around 40-45 m of depth on steep sandy slopes.

Antibiotic resistance genes detected in the marine sponge Petromica citrina from Brazilian coast BJM
Laport,Marinella Silva; Pontes,Paula Veronesi Marinho; Santos,Daniela Silva dos; Santos-Gandelman,Juliana de Fátima; Muricy,Guilherme; Bauwens,Mathieu; Giambiagi-deMarval,Marcia; George,Isabelle.
ABSTRACT Although antibiotic-resistant pathogens pose a significant threat to human health, the environmental reservoirs of the resistance determinants are still poorly understood. This study reports the detection of resistance genes (ermB, mecA, mupA, qnrA, qnrB and tetL) to antibiotics among certain culturable and unculturable bacteria associated with the marine sponge Petromica citrina. The antimicrobial activities elicited by P. citrina and its associated bacteria are also described. The results indicate that the marine environment could play an important role in the development of antibiotic resistance and the dissemination of resistance genes among bacteria.

Callyspongia (Euplacella) biru spec. nov. (Porifera: Demospongiae: Haplosclerida) from Indonesia Naturalis
Voogd, N.J. de.
A new sponge species Callyspongia (Euplacella) biru spec. nov. is described from various locations within Indonesia (NE Bali, SW & NE Sulawesi and NE Kalimantan). The species is assigned to the subgenus Euplacella of the genus Callyspongia because it has brushes of spicules on the nodes of its double-meshed ectosomal skeleton. The species is discussed and compared with relevant Callyspongia records from other Indonesian and neighbouring Indo-Pacific areas.

Checklist de Porifera do Estado de São Paulo, Brasil Biota Neotropica
Custódio,Márcio Reis; Hajdu,Eduardo.
As esponjas (Filo Porifera) são um dos metazoários mais antigos existentes, mas ainda facilmente encontradas em uma grande variedade de ambientes aquáticos. São um componente fundamental em diversos ecossistemas, influenciando diretamente a qualidade da água em seus habitats. Em tempos recentes são um dos grupos que mais fornece novas moléculas bioativas ou com estruturas incomuns. No entanto, são historicamente considerados um grupo de taxonomia complexa e ainda são comuns discussões acerca da sistemática ao nível de ordens ou mesmo da monofilia do grupo. Este cenário começou a ser alterado de forma marcante na última década, a partir de iniciativas multinacionais voltadas a fornecer uma base taxonômica mais sólida. No Brasil, este processo foi...

Evaluation of the community structure of marine sponges in reef patches of the southern Caribbean, Costa Rica Boletín de Investigaciones
Araya-Vargas,Alexander; Busutil,Linnet; García-Rojas,Andrea; Pereira-Chaves,José Miguel; Piedra-Castro,Liliana.
ABSTRACT Marine sponges fulfill many critical functions to coral reefs. In turn, variations in the community structure of the poriferans may indicate changes in the environmental conditions of the ecosystems where they live. However, their study has been scarce in the Caribbean of Costa Rica, mainly in the ecological field. Therefore, the community structure of these organisms was evaluated in four reef patches (Perezoso, Pequeño, Coral Garden, and the 0.36) and it was determined whether it could be explained by sedimentation, substrate, and depth. Relative abundance (RA) and relative coverage (RC) for each species, sponge density, and diversity indices (species richness, Shannon heterogeneity, Pielou's evenness, and Simpson's dominance) were calculated...

Evaluation of the ecological function of amphitoxin in the reef-dwelling sponge Callyspongia (Euplacella) biru (Haplosclerida: Callyspongiidae) at southwest Sulawesi, Indonesia Naturalis
Voogd, N.J. de; Haftka, J.J.H.; Hoeksema, B.W..
The ecological function of the secondary metabolite amphitoxin produced by Callyspongia (Euplacella) biru is evaluated by a forced confrontation with the free-living scleractinian coral Fungia fungites at different exposure times. Our major goal was to determine whether such a forced confrontation with a spatial com­petitor would cause a significant change in the concentration of amphitoxin in the sponge tissue, indicating a regulatory mechanism of amphitoxin production. Firstly, the concentrations of amphitoxin of sponge fragments submitted to forced confrontation with a mushroom coral did not differ between the exposure times. Secondly, all sponge fragments, including the controls had a consistently lower amphitoxin concentration during the course of the...
