Benthic samples collected along the Brazilian central continental margin from Espírito Santo State to Rio de Janeiro State (19° S to 24° S) during the last 20 years and at depths of 50–2200 m yielded the description of six new species of Typhlotanais in the deep-sea (> 200 m): Typhlotanais andradeorum sp. nov., T. bolarticulus sp. nov., T. ischnoch...
even small vertebrates. On March 1th, 2016, during a herpetological survey we observed a subadult male B. erythromelas road-killed with a dead centipede popping out from its body. We believe that the centipede was ingested by the snake, and broke out through the snake's body when it was run over. Our report is the first predation record between the...
Oceanic islands are known by their unique evolutionary histories and high endemicity
caused by isolation. This is the first survey on the biodiversity of Peracarida from
Trindade Island, a volcanic island located about 1,160 km off the Brazilian coast, with
the first reports of Tanaidacea from the island and the description of Synapseudes isis
sp....
The beach-hopper Speziorchestia tucurauna (Müller 1864) is reported for the first time from Fernando de Noronha Archipelago. This is the second record of S. tucurauna from an oceanic island, which has been reported from Rocas Atoll, and the first record of Talitridae for the island. Seven beaches along the island were surveyed, and S. tucurauna was...
Based on specimens collected from eulittoral zone in rocky shores of northeast of Rio de Janeiro (Brazil) on 2017, two new ta-naidaceans species from two different suborders are described: Apseudomorpha brasiliensis sp. nov. (Apseudomorpha, Metapseu-didae) and Pseudozeuxo fischeri sp. nov. (Tanaidomorpha, Pseudozeuxidae). Diagnostic characters of A...
Zoological collections are fundamental repositories of biodiversity and have an important role in scientific dissemination. The National Institute of Mata Atlântica (INMA, previously called Professor Mello Leitão Biology Museum) founded by Augusto Ruschi is situated in Santa Teresa, Espírito Santo, Brazil, within the Atlantic Forest Biome, being a...
Benthic samples collected along the Brazilian coast yielded the description of four new species from three genera of Typhlotanaidae: one Hamatipeda (H. prolata), one Meromonakantha (M. mauri) and two Paratyphlotanais (P. apletos and P. bessai). A new genus Targaryenella is erected to accommodate Meromonakantha anarsios and differences between Targa...
We report herein the first record of necrophagy on Rhinella granulosa (Spix, 1824) (Anura, Bufonidae) by the aquatic beetles Tropisternus (Pristoternus) apicipalpis (Chevrolat, 1834) family Hydrophilidae, and Thermonectus succinctus (Aubé, 1838) family Dytiscidae. The behavioural biology record is presented with precise identification at the specie...
The present study investigates the occurrence of crustaceans inhabiting shells of Triphoroidea (consisting of small-sized gastropods, with right or left coiling) along the western Atlantic. Shells of the newtoniellid Retilaskeya emersonii were occupied by the tanaidacean Pagurotanais bouryi and one hermit crab (Paguridae sp. 1), and possibly by the...
Presentation of unpublished results from my thesis (Typhlotanaidae morphological phylogeny) with highlights of some interesting groups found.
Two new species of deep-sea Tanaidacea (Aremus islandica n. sp. and A. brasilica n. sp.) were collected in the SW and N Atlantic during the scientific cruises organized within the HABITATS and IceAGE (Icelandic Animals Genetic and Ecology) initiatives in 2009 and 2011, respectively. Both species fit well to the current definition of Typhlotanaidae,...

The Southern Ocean is a very sensitive ecosystem, with the Antarctic Peninsula being one of the most rapidly warming regions on Earth. Accordingly, studies of its biodiversity are of urgent interest. In this context, taxonomical surveys of Antarctic tanaidacean species become relevant, since it is one of the lesser-known Antarctic macrofaunal group...
A total of 3109 crustaceans belonging to 50 taxa distributed in 42 families were found in 117 analysed stomachs of flying gurnard (Dactylopterus volitans). Samples were obtained in April 2008 by the R/V Gyre using a bottom trawl towed in 12 stations at 14–100 m depth on the continental shelf of the Campos Basin, Brazil. The carcinofauna was analyse...
Samples from deep benthic areas in the Bransfield Strait, Antarctica, revealed the presence of two new species of Colletteidae: Filitanais elongatus sp. nov. and Macrinella lavradoae sp. nov. Filitanais elongatus sp. nov. resembles F. moskalevi in its habitus; it can, however, be distinguished by characters such as the pleonites and pleotelson with...
The lizard species Ameiva ameiva (Linnaeus, 1758) is widely distributed across the Neotropical region from Panama and Caribbean Islands to the north of Argentina, east of the Andes (Vanzolini et al. 1980. Répteis das Caatingas. Academia Brasileira de Ciências, Rio de Janeiro, Brasil. 161 pp.; Peters and Donoso-Barros 1986. Catalogue of the neotropi...

We observed one female of T. fluviatilis feeding on a dead adult female of R. ornata on 15th September 2014 at the district of Lídice, municipality of Rio Claro, state of Rio de Janeiro, southeastern Brazil (22.781618°S, 44.232212°W; Altitude ca. 660 a.s.l.). At the previous night, this female was observed in amplexus with a male, during egg-cord o...
Two new species of family Tanaopsidae, genus Tanaopsis, from
Admiralty Bay (Antarctica) are herein described. Tanaopsis
brevicorpus sp. nov. displays antennule article 1 about 1.5 times as long
as wide, carapace as long as first three pereonites, both rami of uropod biarticulate
with fusion line, and pleotelson short, more than twice longer than wi...

During the proposed doctoral study, Tanaidacea of family Typhlotanaidae collected during the projects as REVIZEE, Oceanprof and HABITAT will be identified to the species level. For each species a plate illustrating diagnostic characters will be made. New species will be described in detail and plates with drawings of appendages will be made. Geographic distribution maps of the species found along the Brazilian coast will be developed. A dichotomous and pictorial key of Typhlotanaidae species of Brazil will be made and then, a phylogenetic analysis using morphological characters will be performed to assess the relationships between the genera of Typhlotanaidae.
