  • 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.

  • Some Metazoan Parasites from Marine Mammals Stranded in California1
    Some Metazoan Parasites from Marine Mammals Stranded in California1 Marlene M. Colón-Llavina,2,8 Simonetta Mattiucci,3 Giuseppe Nascetti,4 James T. Harvey,5 Ernest H. Williams Jr.,2 and Antonio A. Mignucci-Giannoni6,7,8,9 Abstract: We used morphological and genetic identification to document metazoan parasites of cetaceans and pinnipeds from 28 carcasses salvaged in California between 1974 and 2002, including whales, dolphins, porpoises, sea lions, and seals. Nematodes found included Anisakis simplex (s.l.), A. simplex (s.s.), Pseudoterranova decipiens (s.l.), Pseudoterranova sp., Contracaecum ogmorhini (s.l.), Contracaecum sp., Stenurus cf. minor, Pharurus cf. dalli, and Otostrongylus circumlitus. Cestodes found included Phyllobothrium delphini and Tetrabothrius sp. The acanthocephalan Bolbosoma capitatum, and the arthropod Halarachne miroungae, also were documented. Tetrabothrius sp. in the pygmy beaked whale (Mesoplodon peruvianus) and P. delphini in the Eastern North Pacific long-beaked common dolphin (Delphinus delphis bairdii) constitute two new host records.

  • Known and Inferred Distributions of Beaked Whale Species (Cetacea: Ziphiidae)
    J. CETACEAN RES. MANAGE. 7(3):271–286, 2006 271 Known and inferred distributions of beaked whale species (Cetacea: Ziphiidae) COLIN D. MACLEOD*, WILLIAM F. PERRIN+, ROBERT PITMAN+, JAY BARLOW+, LISA BALLANCE+, ANGELA D’AMICO#, TIM GERRODETTE+, GERALD JOYCE**, KEITH D. MULLIN++, DEBRA L. PALKA¥, AND GORDON T. WARING¥ Contact e-mail: [email protected] ABSTRACT Information regarding beaked whales is so sparse that even the most basic aspects of their biology, such as their distribution, remain poorly defined for some species. We have reviewed the known distribution of each beaked whale species and where possible, used this information to infer its global distribution. While for some species, such as the relatively commonly recorded Cuvier’s beaked whale, the inferred distribution is likely to be an accurate reflection of the species’ actual distribution, for other lesser known species, such as the spade-toothed whale, the inferred distribution is more tentative. However, even such limited distribution information is essential when assessing and mitigating potential anthropogenic impacts on beaked whales and serves to highlight gaps in our knowledge that need to be filled if assessment and mitigation are to be successfully conducted. KEY WORDS: DISTRIBUTION; NORTHERN HEMISPHERE; SOUTHERN HEMISPHERE; CONSERVATION INTRODUCTION Stranded animals may have drifted, either incapacitated or as dead carcasses, for long distances before making landfall, To understand the extent to which beaked whales may be meaning that such evidence may not reflect the actual affected by anthropogenic activities, it is essential to know distribution of the species. Finally, while a great deal of where they occur.

A ca. 1m neonate was observed for the first time. The occurrence of lesser beaked whales in shallow water habitat (20-70m depth) is unusual in the Family Ziphiidae. On 17 December 1997, during the IWC 3rd Blue Whale Survey off Chile, researchers (including two of the authors) assigned another beaked whale sighting at 20º26’S, 70º44’W, in deeper water (878-1245m), as a probable M. peruvianus. All individuals shared the following characteristics: small body size, short snout, nondescript dark colouration dorsally and a low, markedly triangular dorsal fin. An adult beaked whale skull (specimen GPS004) was collected at Los Choros beach (29º17.04’S, 71º23.54’W) in May 1995.

  • Global Cetacean Summary Report
    CONSERVATION AND VALUES GLOBAL CETACEAN SUMMARY REPORT This is a summary report on research commissioned by the Australian Government and undertaken by the Southern Cross University Whale Research Centre and Syneca Pty Ltd, Sydney Australia. The findings draw from a wide range of current literature, notably the reports of the International Union for Conservation of Nature (IUCN) and the International Whaling Commission (IWC). In the interests of brevity, references have not been included in this report although they can be obtained from the original reports which are available on the Department of the Environment, Water, Heritage and the Arts website at www.environment.gov.au/coasts/species/cetaceans/index.html The views and opinions expressed in this publication are those of the authors and do not necessarily reflect those of the Australian Government or the Minister for the Environment, Heritage and the Arts. Acknowledgments Research and analysis provided by: Professor Peter Harrison, Daniel Burns, Christine Fury, and Greg Luker, Southern Cross University Whale Research Centre; and, Peter Dempster and Ron Groenhout from Syneca Consulting Pty Ltd. The GIS distribution maps were developed and funded through the Southern Cross University Whale Research Centre. We thank the IUCN for access to cetacean distribution data files, Maree Blewitt for work on the cetacean distribution maps, and Renee Carter for assisting with compiling the summary report. The Southern Cross University Whale Research Centre researchers consulted Dr Bill Perrin and Professor Scott Baker.

They also have a pair of throat grooves below and behind the lower jaw. A notable characteristic is a slight depression or pocket of the body wall that allows a beaked whale to hold its pectoral flippers tightly against its body. The tail flukes are relatively large and lack a median notch, which is seen in most other cetacean species. A characteristic that helps to distinguish beaked whale species from each other is their teeth.
