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 paper presents for the first time a checklist of the fish fauna of Araça Bay, São Sebastião Channel, northern coast of São Paulo state, Brazil. Fishes were sampled in five surveys from October 2012 to February 2014 using nine different types of sampling gear during high tide. Tide pool fishes were also sampled in four surveys from March to October 2014. Geographic distribution and conservation status of each species are reported. A total of 126 species was recorded in Araçá Bay, including two non-native species and new records in the São Sebastião region for 16 species. The fish species richness found in Araçá Bay was greater than the previously recorded for the São Sebastião Channel and other adjacent areas. Most of the Araçá fish species show a wide distribution along the western Atlantic Ocean (32%). Few species are included in the international (29%) and Brazilian (3.3%) official lists of threatened species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
