List of Marine Mammal Species and Subspecies Written by The
List of Marine Mammal Species and Subspecies Written by the Committee on Taxonomy The Ad-Hoc Committee on Taxonomy , chaired by Bill Perrin, has produced the first official SMM list of marine mammal species and subspecies. Consensus on some issues was not possible; this is reflected in the footnotes. This list will be revisited and possibly revised every few months reflecting the continuing flux in marine mammal taxonomy. This list can be cited as follows: “Committee on Taxonomy. 2009. List of marine mammal species and subspecies. Society for Marine Mammalogy, www.marinemammalscience.org, consulted on [date].” This list includes living and recently extinct species and subspecies. It is meant to reflect prevailing usage and recent revisions published in the peer-reviewed literature. Author(s) and year of description of the species follow the Latin species name; when these are enclosed in parentheses, the species was originally described in a different genus. Classification and scientific names follow Rice (1998), with adjustments reflecting more recent literature. Common names are arbitrary and change with time and place; one or two currently frequently used in English and/or a range language are given here. Additional English common names and common names in French, Spanish, Russian and other languages are available at www.marinespecies.org/cetacea/ . The cetaceans genetically and morphologically fall firmly within the artiodactyl clade (Geisler and Uhen, 2005), and therefore we include them in the order Cetartiodactyla, with Cetacea, Mysticeti and Odontoceti as unranked taxa (recognizing that the classification within Cetartiodactyla remains partially unresolved -- e.g., see Spaulding et al ., 2009) 1. -

Flores2 1Centro de Ciências Biológicas, Universidade Federal de Santa Catarina and International Wildlife Coalition, Brasil 2Centro Nacional de Pesquisa, Conservação e Manejo de Mamíferos Aquáticos – CMA, ICMBio CMA SC – Rod. Maurício Sirotsky Sobrinho, s/n, km02, Jurerê, Florianópolis, SC, 88053-700, Brasil Abstract: The aim of this study was to characterize the feeding behavior of the Guiana dolphin, S. guianensis, through description and quantification of the strategies used by the dolphins, and possibly to apply this patterns to other areas in its distribution. Data were collected during systematic boat surveys, between November/1996 and May/1997, with 120 hours and 13 minutes of total observations. Scheffé Test was utilized to determine whether some strategies were used more than others. Six basic strategies of dolphin feeding behavior were identified: Individual Random Feeding (IRF), Group Random Feeding (GRF), Circular Cooperative Feeding (CCF), Front Cooperative feeding (FCF), Crossing Cooperative Feeding (CRF) and Zig-zag Cooperative Feeding (ZCF). The strategy GRF was statistically different from the others (Scheffé 5%). Previous studies suggested that S. guianensis exhibit two basic feeding strategies, while here we show greater diversity on the feeding behavior, with more complex and varied foraging strategies than previously reported for this species. Observed variation in the coordination of individuals, group cohesion, movement patterns, prey availability and environmental features, demonstrates the complexity of the S. guianensis feeding behavior.

Coordinated Feeding Behavior of the Guiana Dolphin, Sotalia Guianensis (Cetacea: Delphinidae), in Southeastern Brazil: a Comparison Between Populations

Rodovia BR 465 km 7, 23890-000 Seropédica, RJ, Brazil. 2 Corresponding author: E-mail: [email protected] ABSTRACT. The coordinated feeding tactics used by delphinids are influenced by differences in the distribution of prey species, season, and opportunities for social learning. In the present study, we compared the coordinated feeding behavior of two populations of the Guiana dolphin, Sotalia guianensis, in southeastern Brazil, and how these feeding tactics vary seasonality and in the presence of calves. We observed eight types of coordinated feeding tactics, which differed in frequency and in the mean number of individuals engaged in them, and between both areas. Feeding tactics used to herd and capture prey were the most frequent and engaged a greater number of individuals, suggesting that these tactics are better for capturing fish that gather in larger schools. Furthermore, the seasons influenced the occur- rence of different prey items, which in turn modified the feeding tactics of the dolphins. In the Ilha Grande Bay we observed that bouts lasted longer and larger groups engaged in the feeding tactics, which may be associated with the seasonal spawning of larger schooling fish such as Sardinella brasiliensis (Steindachner, 1879) (Teleostei: Clupeidae). -
Guiana Dolphins, Sotalia Guianensis (Cetacea: Delphinidae)

Avenida 24-A 1515, Bela Vista, 13506-900 Rio Claro, São Paulo, Brazil, E-mail: [email protected] ABSTRACT. The aim of the present study was to provide a preliminary description of habitat use by Guiana dolphins, Sotalia guianensis (Van Bénéden, 1864) in the Paranaguá Estuarine Complex (PEC), state of Paraná, Brazil. Approxi- mately 124 km2 were surveyed by small boat from April 2006 to July 2008 in the following subsets of the PEC: Canal do Superagui (~28 km2); Pinheiros Bay (~34 km2); part of Laranjeiras Bay, which included the Guaraqueçaba sub-estuary (~38 km2); and part of the Mixture Section of the PEC (~24 km2). Our efforts were unevenly distributed in the study area. During 55 survey days covering seven distinct seasons, we spent 165 hours observing 323 groups of S. guianensis. Group size varied from two individuals to aggregations as large as approximately 100 dolphins. A total of 49,921 photographs were analyzed; 15,038 (30%) were considered useful for identification purposes. A total of 182 individuals were catalogued, from which 122 (67%) were cataloged in the last three seasons, when the surveyed area was ex- panded. -

In addition, there has been much speculation on the identity of cetaceans inhabiting these brackish waters. Vantage point observations conducted from September 2008 to October 2010 resulted in the observation of 44 groups of dolphins and 79 individuals. Among these, 56 were Inia geoffrensis (71%) and 23 Sotalia. In addition, 21 boat transects were conducted and recorded 50 individuals in 19 sightings. Among sighted during transects 36 were Sotalia (72%) and 14 were Inia. In both observation methods, Tasco Offshore binoculars were used and size and group composition and behaviour (feeding, resting, socializing, travelling and not identified) were recorded. -

For the purpose of this study all dolphin sightings were classified as groups or aggregations. Groups (N ¼ 268, x ¼ 20, range ¼ 1–90) consisted of dolphins in apparent association usually engaged in the same behaviour and moving in the same direction. Aggregations (N ¼ 108, x ¼ 204, range ¼ 100–450) consisted of temporal association of numerous groups gathered in an area, totalling several hundred individuals usually engaged in the same behaviour but not necessarily moving in the same direction. Guiana dolphin groups and aggregations differed significantly in behavioural activity, spatial and temporal distri- bution and age composition. Most aggregated dolphins were engaged in foraging/feeding activities and primarily located at the interior of the bay, and also, aggregations were more likely recorded during morning hours and had more neonates and calves present when compared to groups. The plotted GPS records of aggregations formed two distinct clusters of distribution within the bay, indicating potential areas where conservation strategies could be implemented. -

Editor in charge: Clara Stefen Abstract We conducted a study to assess the populations of the two potentially endangered river dolphin species Inia geoffrensis and Sotalia flu- viatilis in the river systems of the Río Tigre and the Río Marañon in the Peruvian Amazon region. Various observation methods were used and evaluated along ca. 353 kilometres of river and 134 to a maximum of 173 dolphins were recorded from 125 sightings and about 2000 photographs. Only about 10% of these dolphins could not be determined to species level, at least 57 individuals were identified asS . fluvia- tilis, and 89 individuals as I. geoffrensis. The abundance of dolphins along the entire stretch was 0.13 individuals per km for S.
