In this paper, we diagnose a new genus of Sclerodactylidae, Coronatum gen. et sp. nov., from shallow waters of the southwestern Atlantic Ocean. Coronatum baiensis sp. nov. has a compact calcareous ring with short posterior processes and a unique set of body wall ossicles, composed of two-pillared tables, which do not have any morphological affiniti...

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian mega...

The present study explores rare but taxonomically and geographically widespread cases of anterior body axial bifurcation in adult sea cucumbers (Echinodermata: Holothuroidea). One individual of Holothuria ( Halodeima ) grisea , a common intertidal species along the Atlantic coast of Brazil, was studied externally and internally. Individuals of Apos...

Catálogo Taxonômico da Fauna do Brasil: se ng the baseline knowledge on the animal diversity in Brazil

Tropiometra carinata é uma espécie com ampla distribuição mundial, ocorrendo em toda a costa Brasileira. Em sua monografia sobre Comatulida, Clark (1947) designou quatro subespécies baseando-se no número de cirros e cirrais, continuidade da carenagem e tamanho dos braços. Entretanto, os caracteres apresentam sobreposição, não sendo possível determi...

Apesar de descender de ancestrais fortemente calcificados, o endoesqueleto dos holoturóides é reduzido e composto por ossículos microscópicos e um anel composto por placas calcárias conectadas por tecido conjuntivo. O anel calcário é uma estrutura complexa e a falta de conhecimento aprofundado sobre a sua evolução tem gerado interpretações ambíguas...

Espécimes de Pseudoboletia têm sido regularmente encontrados em águas brasileiras desde 2012, especialmente em áreas de proteção ambiental. A identidade destes espécimes permanece desconhecida devido à ausência de características morfológicas diagnósticas e à falta de dados moleculares das espécies atlânticas. O aparecimento súbito deste ouriço-do-...

Deuterostomes are the major division of animal life which includes sea stars, acorn worms, and humans, among a wide variety of ecologically and morphologically disparate taxa. However, their early evolution is poorly understood, due in part to their disparity, which makes identifying commonalities difficult, as well as their relatively poor early f...

The Smithsonian Institution’s National Museum of Natural History (NMNH) comprises federal and non-federal staff, academic appointees (e.g., postdoctoral researchers, students, and interns), volunteers, and contract personnel working in research, collections, education, exhibits, and outreach. NMNH’s international brand provides a public-facing voic...

Despite descending from heavily calcified ancestors, the holothuroid skeleton is fully internal and composed of microscopic ossicles and a ring of plates bound by connective tissue, the calcareous ring. The calcareous ring exhibits a complex and poorly understood morphology; as a result, establishing unambiguous homology statements about its macros...

Material suplementar do nosso artigo "Taxonomy of the sea stars (Echinodermata: Asteroidea) from Bahia State, including ontogenetic variation and an illustrated key to the Brazilian species": (1) chave ilustratada em português e (2) tabela com a batimetria de cada espécie (bathymetry of each species).

Describing ontogenetic morphological change is an important part of integrative taxonomy; still, most taxonomic studies are based only on adult characters. Here, we provide illustrations and a morphological description of the sea stars from Bahia, including ontogenetic and intraspecific variation, and identify taxonomic issues. A total of 293 speci...

Here, we review the taxonomy of the Apodida species from the Brazilian coast and oceanic islands. Eleven species are reported, four Chiridotidae (including Chantalia conandae gen. et sp. nov.) and seven Synaptidae (including Yemoja gen. nov.). Chantalia conandae gen. et sp. nov. is a shallow-water species diagnosed by having 12 tentacles, 4–6 Polia...

Inclusion of fossils can be crucial to address evolutionary questions, because their unique morphology, often drastically modified in recent species, can improve phylogenetic resolution. We performed a cladistic analysis of 45 cassidulids with 98 characters, which resulted in 24 most parsimonious trees. The strict consensus recovers three major cas...

Thyone and Havelockia are worldwide-distributed genera represented in the Western Atlantic by eight and three species, respectively. In this paper, we describe two new shallow-water species from the Brazilian coast: Thyone waltinhoi sp. nov. and Havelockia oraneae sp. nov. These genera are very similar morphologically but the presence of subdivisio...

Here we use synchrotron radiation-based micro-computed tomography (SRµCT) images of type specimens to confidently place Cassidulus malayanus in a new genus (Kassandrina gen. nov.) that would not have been discovered with traditional techniques, and to describe a new species of Cassidulus (Cassidulus briareus sp. nov.) from Australia and designate a...

This book is about the environmental characteristics and biodiversity of the North coast of the Bahia State (about 200 km of shoreline), in Brazil; and our chapter focuses on the biodiversity of echinoderms in this region. Specimens were collected mostly from shallow coral reef environments and sandy bottoms of up to 57 m of depth. All five living...

In this paper we describe a new genus and a new species of Chiridotidae based on specimens collected in shallow water off the South-eastern Brazilian coast. Gymnopipina ikamiaba gen. nov. et sp. nov. is characterized by the complete absence of dermal ossicles in the body, and it differs from the other ossicleless apodids in the number of tentacles...

The degree of isolation of oceanic islands makes these environments an excellent model for evolutionary studies. Proper knowledge of the species composition of oceanic islands, however, is required to better understand evolutionary processes (e.g. speciation events). A 3-year survey in the shallow waters (up to 30 m) of the Trindade and Martin Vaz...

In this paper, we propose the reassignment of three western Atlantic species of the order Dendrochirotida to the family Sclerodactylidae (Euthyonidiella occidentalis comb. nov., Euthyonidiella arenicola comb. nov., and Thandarum manoelina comb. nov.) with a discussion on the classification of the dendrochirotids based on the morphology of the calca...

Thyone pawsoni and Holothuria (Theelothuria) princeps are reported from shallow water of the South Atlantic Ocean. A morphological description of these new records with colour figures and scanning electron microscopy images of their ossicles are provided. With these two new records for the Brazilian Coast, the genus Thyone is now represented by two...

The ornamental marine trade has increased on a worldwide scale. Although Brazil is amongst the major exporters, data about this activity are underestimated. Therefore, the profile and consequences of such activity to the wild populations are not fully understood. In spite of being basically supported by fish collection, charismatic invertebrates al...

Cassidulus infidus Mortensen 1948b is one of the few recent species of the family Cassidulidae Agassiz & Desor 1847 and known only from its poorly described holotype. In Brazil, this family is represented only by two extant species and, to date, both are endemic to Bahia (C. infidus) and Rio de Janeiro (Cassidulus mitis Krau 1954). After a century...
