This study describes five species of tetillid sponges from deep waters of the Brazilian economic exclusive zone; three are new, one is a new occurrence, and another is a known species which is here analyzed. The new species found are: Cinachyrella clavaeformis sp. nov. from the Columbia Seamount (85 m depth), Cinachyrella strongylophora sp. nov. from the Almirante Saldanha Seamount (270 m depth) and Craniella curviclada sp. nov. from slope of the Espírito Santo Basin (500 m depth). The two new species of Cinachyrella possess microacanthoxeas like those found in Cinachyrella kuekenthali (Uliczka 1929); this last species occurs in Caribbean region (4-100 m depth) and in N, NE and SE Brazil (0.2-100 m depth). The type material of Craniella corticata (Boury-Esnault 1973); from NE Brazil (75 m depth), has been found to be a synonym of Cinachyrella kuekenthali. Craniella ...

Biemna apresenta 57 espécies conhecidas para o mundo, com seis registradas para o Atlântico Tropical Ocidental, sendo três para o Caribe: Biemna caribea Pulitzer-Finali, 1986; Biemna microstyla de Laubenfels, 1950; Biemna oxeata van Soest & Stentoft, 1988; e três para o Brasil: Biemna microacanthosigma Mothes, Hajdu, Lerner & van Soest, 2004; Biemna spinomicroxea Mothes, Campos, Lerner, Carraro & van Soest, 2005 e Biemna trisigmata Mothes & Campos, 2004. Todos os registros brasileiros são restritos para o Estado do Amapá. Este trabalho teve como objetivo descrever uma nova espécie de Biemna.

Clathria (C.) calypso is also redescribed. Specimens previously recorded from Brazil as Clathria (C.) prolifera were considered to fit better in the taxon Clathria (Wilsonella). The new species was compared with all other (twenty-five) Clathria (C.) species occurring in the Atlantic. The new species differs from the other species by overall morphology and presence of auxiliary tylo-strongyle megascleres.

Clathria (Axosuberites) Topsent, 1893 is characterized by having digitate, whip-like, arborescent and flabellate growth forms, lacking echinating spicules, well differentiated axial and extra-axial skeleton, styles and/or subtylostyles as principal spicules, and microscleres palmate isochelae and toxas. The subgenus contains 19 valid species, with worldwide distribution predominantly in shallow waters. Six species occur in the Atlantic Ocean and two of them are recorded from the Western Atlantic in South America: Clathria (Axosuberites) riosae Van Soest, 2017, and Clathria (Axosuberites) marplatensis (Cuartas, 1992). Specimens analyzed in this study were collected in 2015 at Mamanguape estuary, Paraíba State, and in 2017 at Tutóia beach, Maranhão State. Here we described two new species of Clathria (Axosuberites) for the first time in Brazi...

Up to date, only four species are known for the Brazilian coast (Muricy 2018): Characella aspera Sollas, 1886, C. capitolii Mothes et al. 2007, C. pachastrelloides (Carter, 1876), and Pachastrella monilifera Schmidt, 1868. In this study, a new species of Characella is described from the mesophotic zone off Bacia Potiguar (Rio Grande do Norte State, Northeastern Brazil). The specimen was preserved in 80% ethanol and deposited in the Porifera Collection of the Universidade Federal de Pernambuco (UFPEPOR). Taxonomic comparisons were made with data tabulated for all species of Characella available in the World Porifera Database (van Soest et al. 2018).

Strongylacidon oxychaetum sp. nov. has thinly encrusting shape with lobate pro-jections, strongyles, oxychaetes and arcuate chelae; S. solangeae sp. nov. is characterized by having massive shape with hispid surface, strongyles and unguiferate chelae; and S. chelospinata sp. nov. present thinly encrusting shape, strongyles, and arcuate isochelae with large spines on the outer edge of the axis. An identification key for the nine valid species of Strongylacidon from the Tropical Western Atlantic is provided. New morphological characters, viz., oxychaetes and spined arcuate isochelae (here termed acanthochelae), are added to the definition of the genus Strongylacidon and of the family Chondropsidae.

Para uma aprendizagem significativa, espera-se que um estudo contextualizado da fauna regional, aproveitando-se do ambiente imediato, seja contemplado nas aulas de Ciências, notadamente em regiões de grande biomassa de determinados grupos animais.

It is the only Dercitus (Stoeba) with four-rayed calthrops and discorhabds-like sanidasters. This is the 16th species of the genus to be recognized worldwide, the sixth from the Atlantic. The new species is compared with all its congeners worldwide.
