Sponges (Porifera) are a diverse and globally distributed clade of benthic organisms, with an
evolutionary history reaching at least the Ediacaran‐Cambrian (541 Ma) boundary interval. …

The sponge species Chondrilla nucula has a simple morphology and a very wide geographical
distribution. To verify whether the latter might be an artifact of the former, samples of this …

… Carreaux and Jean-Pierre Bazureau synthesized and provided leucettamine B,
polyandrocarpamine A/B, aplysinopsine and dispacamide A; Aline Alencar and Michelle Klautau …

Eurythoe complanata (Pallas 1766) has been considered a cosmopolitan species with a great
morphological similarity across its geographic range. To elucidate whether E. complanata …

The genus Clathrina has one of the most difficult systematic arrangements in the Porifera,
Class Calcarea. Few morphological characters can be used to describe its species, and the …

Many sponge species are considered to be cosmopolitan. However, the systematics of marine
sponges are very difficult because of the paucity of taxonomically useful characters, and …

Sponge systematics has been traditionally based on the study of the skeleton (spicules and
spongin fibres). However, sponges of the genus Chondrosia are devoid of those skeletal …

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 …

Most biological groups are still longing for a phylogenetically sound taxonomic organization.
In this article, we aimed to verify the consistency of morphological characters in calcarean …

… We explored only shallow water habitats (0–30 m), such as mangroves, reefs or rocky bottoms
and underwater caves. According to this study, the sponge fauna of Martinique is currently …
