“…The first report of cetacean strandings at Ceará state (Alves-Júnior et al , 1996) documented 14 cetacean species. Another five species were recorded after 1996, including northernmost records of the Gervais' beaked whale, Mesoplodon europaeus (Martins et al , 2004) and Antarctic minke whale, Balaenoptera bonaerensis (Meirelles & Furtado-Neto, 2004) in the south-western Atlantic, the first record of the Fraser's dolphin, Lagenodelphis hosei , in north-eastern Brazil (Barros et al , 2001), and the first strandings of B. acutorostrata (Meirelles et al , in press), pygmy sperm whale, Kogia breviceps , killer whale, Orcinus orca , and spinner dolphin Stenella longirostris (this paper) in Ceará.…”

This study reviews and updates information on cetacean strandings in the state of Ceará, Brazil (02830 0 S 41815 0 W-04830 0 S 36845 0 W), comprising 573 km of coastline. In the years 1992-2005, there were 252 cetacean stranding events, representing 19 species: three species of Balaenopteridae, three Physeteridae, two Kogiidae, two Ziphiidae and 11 Delphinidae. Three species comprised the majority (78.9%) of stranding events: estuarine dolphin, Sotalia guianensis (61.9%); sperm whale, Physeter macrocephalus (10.3%); and rough-toothed dolphin, Steno bredanensis (6.7%). There was an increasing trend in the number of cases reported in the first five years with a highest frequency achieved in 1996. Stranding events occurred throughout the year, with the lowest frequency occurring in the autumn (March-May). Approximately 4% of the events were attributed to natural causes while 24.6% were human-related, mainly incidental captures. Meat removal for human consumption or bait was recorded in 6.7% of events. In the study area, Sotalia guianensis, P. macrocephalus and Steno bredanensis were the most abundant cetacean species, whereas Lagenodelphis hosei, Pseudorca crassidens, Orcinus orca, Kogia sima, Mesoplodon europaeus, Balaenoptera acutorostrata and Balaenoptera bonaerensis are probably rare in the area.

“…infecting this cetacean in Brazil. The geographical distribution of M. europaeus was expanded recently to South Atlantic waters (Culik, 2010) after stranding reports on the Brazilian coast (Santos et al , 2003; Martins et al , 2004), minimizing the possibility of accidental occurrence of this species in the littoral of this country. The present data are coherent with the phylogeny tanglegram of Anisakis sp.…”

“…The Gervais' beaked whale, Mesoplodon europaeus , occurs mainly in North Atlantic waters, but its distribution has been extended to the South Atlantic Ocean following stranding reports on the Brazilian coast (Santos et al , 2003; Martins et al , 2004). The only anisakid species that has been reported infecting this whale is A. ziphidarum (Cavallero et al , 2011).…”

First record of the anisakid nematode Anisakis nascettii in the Gervais' beaked whale Mesoplodon europaeus from Brazil

Anisakid nematodes are parasites with an indirect life cycle, involving many hosts, including cetaceans that act as definitive hosts. Identification at species level is crucial for a better understanding of the epidemiology and ecology of these parasites, but an accurate diagnosis based only on morphology is difficult. In Brazil, genetic characterization of anisakids is still rare, with Anisakis typica and A. physeteris being the only two species identified by genetic markers until now. The definitive hosts of A. nascettii are Mesoplodon grayi, M. bowdoini, M. layardii and M. mirus. Geographical locations of A. nascettii include the coasts of New Zealand, South Africa and Europe. In this study, a nematode was collected from a Gervais' beaked whale, Mesoplodon europaeus, stranded in Ceará State, north-east Brazil. Genetic analysis based on 18S rDNA, internal transcribed spacer (ITS) region and mtDNA cox2 gene revealed 100% identity with Anisakis sp. U94365, 99% with Anisakis sp. (MP-2005 EU718477 A. nascettii) and 99% with A. nascettii DQ116431, respectively. Phylogenetic analyses of ITS and cox2 sequences using both neighbour-joining and maximum-likelihood methods provided strong support for a clade with only A. nascettii specimens. This study demonstrated for the first time the identification of A. nascettii in the Brazilian Atlantic Coast, revealing a wider geographical distribution of this parasite worldwide and extending the range of its definitive hosts to a new Mesoplodon species, M. europaeus, the Gervais' beaked whale.

Pantropical spotted dolphins, Stenella attenuata, are found across all tropical and subtropical oceans around the world, but their distribution is poorly known in the Southwestern Atlantic Ocean (SWA). A group of approximately 10 S. attenuata individuals was sighted in deep (~3,000 m), warm (~27.5 °C) and oligotrophic waters, near oceanic banks off northeastern Brazil (02°04’16.68” S and 038°08’28.26” W). This sighting constitute a new record of the northern distribution of S. attenuata in SWA. More survey efforts mustbe carried out to investigate cetaceans distribution along the Brazilian coast, especially inoffshore waters.
