We report, for the first time, the occurrence of the muzzled blenny,Omobranchus punctatus, on the coast of São Paulo, South-Eastern Brazil, partially filling a record gap within the species’ expected distribution in Brazil. One individual was found on 16 June 2014 in a sand-bottom tide pool of a tidal flat ecosystem, adjacent to the port of São Sebastião.

This work reports the second record of the Indo-Paciic invasive mud sleeper, Butis koilomatodon, for coastal São Paulo in southeastern Brazil, and represents the southernmost record for this species in the southwestern Atlantic Ocean. The risks of a potential invasion mediated by anthropogenic impacts on the area of occurrence are also discussed.

This publication is the second in a series that will together constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. Here we present results of morphologic and morphometric analyses of 12 Clupeiform species (3 Clupeidae, 7 Engraulidae and 2 Pristigasteridae) by means of the most commonly used features, measurements and indices. Three otoliths of each species have been illustrated and photographed whenever possible. The frequency of occurrence has been calculated for each characteristic by total length class (TL), and the ontogenetic differences have been analyzed (multiple χ² test; significance 0.05). AbstrActDescriptors: Otoliths, Morphology, Morphometry, Southwestern Atlantic, Brazil, Clupeiformes.Esta publicação é a segunda de uma série que constituirá um Atlas de Otólitos para os Teleostei da região Sudeste-Sul brasileira. Nela são apresentados os resultados de análises morfológicas e morfomé-tricas de 12 espécies de Clupeiformes (3 Clupeidae, 7 Engraulidae e 2 Pristigasteridae) através de feições, medidas e índices usualmente utilizados. Três otólitos de cada espécie foram desenhados e fotografados, sempre que possível. A frequência de ocorrência foi calculada para cada característica por classes de comprimento total dos peixes (CT) e as diferenças ontogenéticas foram analisadas (Teste χ² múltiplo; significância 0,05).

Reproductive parameters of 168 franciscana dolphins, Pontoporia blainvillei (73 females and 95 males) incidentally caught (n = 163) or stranded (n = 5) between 2005 and 2016 in southeastern Brazil are presented. Ovarian macroscopic analysis revealed 55 immature (75.3%) and 18 mature (24.7%) females. Annual pregnancy rate was estimated to be 0.36, with a calving interval of 2.8 years. Testicular histology revealed 66 immature (69.5%) and 29 mature (30.5%) males. Males with combined testis weight above 4 g were mature, and 1-year-old mature males and a 2-year-old pregnant female are reported for the first time for the species. Reproductive seasonality does not seem to occur in the study area. Mean age and length at sexual maturation were estimated to be at 2.7 years and 128.5 cm for females, and 2.7 years and 114.0 cm for males. These estimates are lower than most of the estimates for this species. These results add novel and valuable information on the reproductive patterns of this endangered species, threatened by high levels of mortality in gill net fisheries. The information presented here represents an important effort to obtain more reliable parameter estimates for the studied area, needed for a better assessment of its current conservation status.

To complement the series of manuscripts published as "Atlas of Teleostei Otoliths of the Southeastern-Southern Brazil", in this volume we present results for species of Siluriformes (two species) and Pleuronectiformes (thirteen species) orders. Considering that the sagittae of Siluriformes are very small we analyzed the left lapillus. Due to the asymmetry of the Pleuronectiformes otoliths, were analysed both left and right structures, being the circumsulcal depression the most important feature to diagnose these species. AbstrActDescriptors: Sagittae, Lapilli, Morphology, Morphometry, Siluriformes, Pleuronectiformes.Em complemento à série de manuscritos publicados como "Atlas de Otólitos para os Teleósteos da região Sudeste-Sul do Brasil", neste volume apresentamos os resultados obtidos para espécies das ordens Siluriformes (duas espécies) e Pleuronectiformes (treze espécies). Tendo em vista que os sagittae dos Siluriformes são muito pequenos, foram analisados os lapilli esquerdos. Devido a assimetria dos Pleuronectiformes, foram analisados tanto sagittae esquerdos quanto direitos, sendo a depressão circumsulcal a feição mais importante para diagnosticar as espécies desta ordem.

This publication is part of a series prepared with the purpose to constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. Here we present the results of 15 morphological features and six shape indices for 33 Perciformes species of 20 families. Whenever available in out collection, three otoliths of each species were illustrated and photographed. The frequency of occurrence of each feature was calculated inside and among total length classes being the differences analyzed through multiple χ2 tests (significance level 0.05). Based on otoliths measurements, six shape indices values were obtained being the minimum, maximum, mean and standard deviations values presented.

In addition to the series of documents that we have been publishing on the "Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian region", in this volume we present the results of species of the orders Atheriniformes (1 species), Beloniformes (5), Beryciformes (2), Zeiformes (2), Syngnathiformes (2), Scorpaeniformes (9) and Tetraodontiformes (6). Features, measurements and indices were analyzed according to methodology used in anterior series. Three otoliths of each species have been illustrated and photographed whenever possible. The frequency of occurrence of each characteristic was calculated by total length classes (TL), and differences within and among classes have been analyzed applying the multiple χ2 test (significance 0.05).

This publication is part of a series that will constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. It presents the results of the morphological and morphometric analyses of 31 Perciformes (two species of Centropomidae; two of Acropomatidae; two of Serranidae; two of Priacanthidae; two of Malacanthidae; one of Pomatomidae; six of Carangidae; three of Lutjanidae; five of Gerreidae and six of Haemulidae). Whenever available in the collection, otoliths from three distinct specimen sizes were illustrated and photographed in order to show their variation during development. For each characteristic the frequency of occurrence was calculated within each length class (TL) and among length classes (during development) and differences were analyzed by a multiple χ² test (significance 0.05).
