A gota úrica é uma doença metabólica caracterizada pela deposição de cristais de urato e ácido úrico em tecidos do corpo, que pode acometer répteis, mamíferos e aves. Neste trabalho, relata-se um caso de achados post mortem compatíveis com gota úrica visceral em um exemplar de coruja suindara (Tyto alba) de vida livre. Macroscopicamente, o pericárdio apresentava-se completamente esbranquiçado, espesso e aderido ao miocárdio e o fígado e ambos os rins apresentavam áreas esbranquiçados sugerindo acúmulo de urato. A microscopia do tecido cardíaco e hepático revelou pericardite fibrinosa e perihepatite necrosante respectivamente. Congestão pulmonar e infiltrado inflamatório heterofílico multifocal no parênquima renal também foram visualizados. As alterações encontradas são compatíveis com as descritas na literatura para gota úrica visceral em aves, podendo até serem consideradas como lesões patognomônicas. Este é o primeiro relato de gota úrica visceral em um rapinante de vida livre no Brasil.

A female Cuvier's Beaked Whale ( Ziphius cavirostris ) specimen measuring 580 cm in length died after being stranded in Southeastern Brazil. Following a necropsy, organ samples were obtained, fixed in 10% neutral buffered formalin and histopathologically analyzed. A severe and generalized hypodermis infection by Phyllobothrium delphini (Phyllobothriidae) was observed, resulting in granulomatous panniculitis. Severe renal and arterial lesions were also noted, including a severe bone metaplasia in the aorta artery, associated with a massive infection by Crassicauda sp, (Tetrameridae). A significant thoracic hemorrhage due to thoracic aorta artery rupture was noted, also likely due to this infection, resulting in a fatal injury. This study contributes towards knowledge on histopathologic changes in the scarcely studied Cuvier's Beaked Whale, is the first to associate a Crassicauda sp. infection in this whale species in the Brazilian region and also the first to indicate a resulting osseous metaplasia due to this parasitism and granulomatous dermatitis associated with Phyllobothrium delphini . Furthermore, this is also, to the best of our knowledge, the first report of Phyllobothrium delphini cysts in a Ziphius cavirostris specimen to date.

ResumoEste trabalho tem como finalidade divulgar a utilização de Dermestes maculatus na preparação de material osteológico de diferentes espécies animais e, ao mesmo tempo, contribuir para a diversificação da coleção osteológica da Seção de Anatomia da UENF. Seis animais de diferentes espécies tiveram seus esqueletos limpos pelos insetos. O procedimento de limpeza completa foi obtido em diferentes períodos de tempo e mantinha uma relação direta com o número de larvas e insetos adultos presentes nas colônias. No final da exposição, alguns

We describe an osseous metaplasia in a wild Patagonian green racer (Philodryas patagoniensis). The 5.5×1.5-cm lesion of irregular contour on the right dorsolateral surface proximal to the snake's cloaca was raised, hard, ulcerated centrally, and radiopaque and interfered with mobility. Microscopy revealed osseous metaplasia on skin and muscle.

Saurophagy constitutes an important source of mortality among lizards and has been reported for the genus Tropidurus. However, the extension of this behavior remains unknown. Herein, we record the predation of T. jaguaribanus by its congener T. hispidus. This is the first report of saurophagy among different species of syntopic Tropidurus. Furthermore, whereas published records of saurophagy tend to be directed against juveniles, this case involved two adult individuals. Keywords: Predation, mortality, agonistic interactions, Tropiduridae, Caatinga. Resumo: A saurofagia constitui uma importante fonte de mortalidade entre lagartos e tem sido reportada para o gênero Tropidurus. Contudo, a extensã o deste comportamento permanece desconhecida. Neste estudo registramos a predac¸ão de T. jaguaribanus por seu congênere T. hispidus. Este é o primeiro caso de saurofagia entre diferentes espécies de Tropidurus sintó picos. Além disso, embora a saurofagia tenda a ser direcionada contra jovens, este caso envolveu dois indivíduos adultos.

Although ophiophagy is not a well-known event among neotropical lizards, occasional snake predation events have been reported for some species. For Tropidurus torquatus only one record of predation on Phalotris matogrossensis is currently known. Here we report the second record of ophiophagy in Tropidurus torquatus, adding a new prey item to its known diet, and we provide a review of vertebrate prey consumed by this enigmatic lizard species. Although when compared to other lizard species, T. torquatus has a substantial number of records documenting the predation of small vertebrates, these records are occasional and are likely the result of opportunistic events.

Tricheilostoma salgueiroi occurs in northeastern and southeastern Brazil, in the states of Bahia, Minas Gerais, Espírito Santo and Rio de Janeiro. We collected one adult male of this species at Lagoa de Cima, municipality of Campos dos Goytacazes, state of Rio de Janeiro. This new locality is ca. 40 km SE from the closest known locality of the species and corresponds to its easternmost locality in the state of Rio de Janeiro. We additionally correct a previous distribution report, placing the locality of Cambuci, Rio de Janeiro, under correct geographic coordinates.

The rock river frog Thoropa miliaris (Cycloramphidae) is a saxicolous species endemic to the Atlantic Forest. There is scarce literature on potential predators of this species, which is likely related to the difficulty of recording its predatory interactions. In this paper, we report opportunistic records of predation on T. miliaris by the snake Chironius laevicollis (Colubridae), spiders of the genus Ctenus (Ctenidae), and the bird Furnarius rufus (Furnariidae). In addition, we compiled the reports of predation on T. miliaris from current published data.
