Eurythoe complanata (Polychaeta: Amphinomidae), the ‘cosmopolitan’ fireworm, consists of at least three cryptic species
COI sequences between Pacific and Atlantic lineages were much more divergent than those of other transisthmian invertebrates, indicating their split before the Panama Isthmus closure or a faster evolutionary rate of COI for this species.
DOES COSMOPOLITANISM RESULT FROM OVERCONSERVATIVE SYSTEMATICS? A CASE STUDY USING THE MARINE SPONGE CHONDRILLA NUCULA

The results reject the null hypothesis of cosmopolitanism of C. nucula and indicate that the putative worldwide distribution of some marine sponges, and possibly many other benthic invertebrates, may be the result of overly conservative systematics.
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…
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.
A molecular phylogeny for the order Clathrinida rekindles and refines Haeckel's taxonomic proposal for calcareous sponges.

This study confirms the suitability of skeleton and body anastomosis as valid characters in a phylogenetically sound taxonomy for the order Clathrinida, and finds that Haeckel's original proposal is remarkably similar to the author's own, which was based on a molecular phylogeny 140 years later.
Macrofauna inhabiting the sponge Paraleucilla magna (Porifera: Calcarea) in Rio de Janeiro, Brazil

The results show that P. magna is used as a substrate for attachment and/or shelter by its associates and that most of these associations are just opportunistic, reiterating a previous proposal that sponges are important biodiversity reservoirs and that they should be seriously considered in conservation programmes.
Comparative study of putative conspecific sponge populations from both sides of the Isthmus of Panama

A morphological, cytological and genetic comparison of putative conspecific populations of Spirastrella sp. cf. mollis (Porifera: Demospongiae) from both sides of the Isthmus of Panama revealed a…
How a collaborative integrated taxonomic effort has trained new spongiologists and improved knowledge of Martinique Island (French Antilles, eastern Caribbean Sea) marine biodiversity
The importance of developing exploratory and educational research in areas historically devoid of biodiversity inventories and systematics studies is demonstrated, as well as the necessity to consider not only the number of species but their distribution in space to evaluate their putative contribution to ecosystem services and willingness to preserve them.
Cryptic speciation in a high gene flow scenario in the oviparous marine sponge Chondrosia reniformis
This is the first report of genetic homogeneity in a sponge species over such a large geographical distance, and shows that C. reniformis is not conspecific.
