Three new species of calcareous sponges from the coast of Bahia State, NE Brazil are described. All of them belong to the genus Paraleucilla (Calcaronea, Leucosolenida, Amphoriscidae): P. solangeae sp. nov., P. oca sp. nov., and P. incomposita sp. nov. The number of species recorded from the Bahia coast has thus increased from 10 to 13. Including these new species, there are now 50 calcareous sponge species known from the entire Brazilian coast. Paraleucilla is now composed of 11 species, six… 
Tropical Eastern Pacific Amphoriscidae Dendy, 1892 (Porifera: Calcarea: Calcaronea: Leucosolenida) from the Peruvian coast
Two new species of Amphoriscidae Dendy, 1892 from the northern coast of Peru, Tropical Eastern Pacific, are described integrating molecules and morphology and the phylogenetic analysis, which included the largest number of AmphOriscidae species, was congruent with previous studies.
The presence of the diagnostic character of the genus Paraleucilla (Amphoriscidae, Calcarea, Porifera) may depend on the volume and body wall thickness of the sponges
This work examined the assumption that the size of the sponge may have an effect on the presence or the absence of the disorganized zone (DZ) in the inner region of the skeleton of the latter genus, and described the frequency with which the DZ is absent from individuals of Paraleucilla magna.
Temporal variation in the recruitment of calcareous sponges (Porifera, Calcarea) in Todos os Santos Bay, tropical Brazilian coast
The results contribute to improve the current knowledge on the dynamics of each species found on the plates and reinforce the general view that the pattern of recruitment varies greatly in Calcarea, even amongst sympatric species.
Associated organisms inhabiting the calcareous sponge Clathrina lutea in La Parguera, Puerto Rico
The goal of this study was to characterize infaunal assemblages from a calcareous sponge, Clathrina lutea, across multiple reefs from the La Parguera Natural Reserve, Puerto Rico, with the most abundant associated fauna being copepods and polychaetes.


Taxonomic revision of Leucascus Dendy, 1892 (Porifera: Calcarea) with revalidation of Ascoleucetta Dendy & Frederick, 1924 and description of three new species.
The presence of spines in the apical actine of the tetractines had never been observed in Leucascus, but it was found in all species with tetractorines in their skeletons, and the family Leucascidae is now composed of Ascaltis, Leuc Damascus and Ascoleucetta.
First occurrence of the genus Paraleucilla (Calcarea, Porifera) in the Atlantic Ocean: P. magna sp. nov.
We describe the first species of the genus Paraleucilla Dendy 1892 from the Atlantic Ocean. P. magna sp. nov. is characterized by the presence of triactines composing the atrial skeleton and the
Taxonomy of calcareous sponges (Porifera, Calcarea) from Potiguar Basin, NE Brazil
The taxonomy and distribution of calcareous sponges from Potiguar Basin (Rio Grande do Norte state, Northeastern Brazil) are studied here.
Calcareous sponges (Porifera, Calcarea) from Ilha Grande Bay, Brazil, with descriptions of three new species
This is the first surveillance of calcareous sponges (Porifera, Calcarea) from Ilha Grande Bay in the Southwest coast of Rio de Janeiro, Brazil, and three new species to science are being described here.
Marine sponges of Pernambuco State, NE Brazil
The Brazilian coastline is still poorly studied ftom a faunistic viewpoint. Brazilian sponges are among the less studied in the world, and most of the knowledge about them comes ftom dredging by
Revision of the genus Clathrina (Porifera, Calcarea)
The morphology of several specimens/species of Clathrina, including the type species, was studied and used to produce the first revision of this genus, agreeing with the viewpoint that morphological characters such as type and distribution of spicules, size of actines, spines, and anastomosis of the cormus are useful when establishing the taxonomy of the genus.
Global Diversity of Sponges (Porifera)
Results obtained demonstrate that regional approaches to analytical biogeography are at present more likely to achieve insights into the biogeographic history of sponges than a global perspective, which appears currently too ambitious.
Calcareous sponges from São Paulo State, Brazil (Porifera: Calcarea: Calcinea) with the description of two new species
Calcareous sponges (Calcarea: Calcinea) are being described, for the first time, from São Paulo State, Brazil. A total of five species are described, two of which are new to science (Clathrina
Order Leucosolenida Hartman, 1958
Leucosolenida Hartman (Calcarea, Calcaronea) is emended here to include nine families, and 42 genera. Leucosolenida seems to have evolved from the olynthus grade, a form that is probably present in
