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. -
Dolphin and Orca Behaviour Studies and Individual Identification
Dolphin and orca behaviour studies and individual identification Blue Marine Foundation and Patagonia Projects Project overview - June 2020 1 BLUE MARINE FOUNDATION AND PATAGONIA PROJECTS DOLPHIN AND ORCA BEHAVIOUR AND INDIVIDUAL IDENTIFICATION 2 Dolphin and orca behaviour studies and individual identification Headlines • Toothed whales include dolphins, whales and belugas. • Chile has an endemic dolphin species, the Chilean dolphin (Cephalorhynchus eutropia), and there are thought to be less than 5000 left in the wild. • Each dolphin or orca has a unique pattern of notches and marks on their dorsal fins. • Patagonia Projects started their orca ID catalogue in 2018 and have 14 individuals documented. • The ability to identify individuals allows site fidelity to be studied: which species live in the Golfo de Penas, and how often do they return to the area? Story Very little is known about which odontocete species – toothed whales – frequent the waters of Chilean Patagonia around the Golfo de Penas. In addition, there are past observations of orca hunting sei whales (to the point where they strand on beaches and die) in this area. This prompted the Patagonia Projects team to more closely investigate and document orca behaviour, as well as any other dolphin species encountered. In November 2018, Patagonia Projects collaborated with Dr Isabella Clegg and set up a protocol for on-effort sightings, recording cetacean behaviour and taking photoID data. The aim was to better understand which cetaceans inhabit the area, whether they are residents and whether there is high site fidelity (do they return each year?), and what they are using the area for. -
FC Inshore Cetacean Species Identification
Falklands Conservation PO BOX 26, Falkland Islands, FIQQ 1ZZ +500 22247 [email protected] www.falklandsconservation.com FC Inshore Cetacean Species Identification Introduction This guide outlines the key features that can be used to distinguish between the six most common cetacean species that inhabit Falklands' waters. A number of additional cetacean species may occasionally be seen in coastal waters, for example the fin whale (Balaenoptera physalus), the humpback whale (Megaptera novaeangliae), the long-finned pilot whale (Globicephala melas) and the dusky dolphin (Lagenorhynchus obscurus). A full list of the species that have been documented to date around the Falklands can be found in Appendix 1. Note that many of these are typical of deeper, oceanic waters, and are unlikely to be encountered along the coast. The six species (or seven species, including two species of minke whale) described in this document are observed regularly in shallow, nearshore waters, and are the focus of this identification guide. Questions and further information For any questions about species identification then please contact the Cetaceans Project Officer Caroline Weir who will be happy to help you try and identify your sighting: Tel: 22247 Email: [email protected] Useful identification guides If you wish to learn more about the identification features of various species, some comprehensive field guides (which include all cetacean species globally) include: Handbook of Whales, Dolphins and Porpoises by Mark Carwardine. 2019.

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.

Introduction Blue whales are known principally by two contrasting accolades, firstly, as being the largest animal to have ever lived on Earth, and secondly, as having been hunted to near extinction during twentieth century whaling. During the whaling era over four thousand animals were caught in Chilean waters alone (Williams et al. -
Lagenorhynchus Obscurus – Dusky Dolphin
Lagenorhynchus obscurus – Dusky Dolphin to be split in due course (LeDuc et al. 1999; Harlin- Cognato 2010). Several recent phylogenies have shown that L. obscurus consistently groups with L. obliquidens (Pacific White-sided Dolphin) and separately to L. australis (Peale’s Dolphin) and L. cruciger (Hourglass Dolphin). The two North Atlantic members of the genus (L. albirostris, the White-beaked Dolphin, and L. acutus, the Atlantic White-sided Dolphin) appear distinct from all other members of the genus. Current thinking would either split L. obscurus and L obliquidens into the genus Sagmatius (LeDuc et al. 1999; May-Collado & Agnarsson 2006) or make it an entirely new genus (Harlin-Cognato 2010). Sara Golaski / Namibian Dolphin Project Three subspecies of Dusky Dolphin are generally suggested based on both molecular (Harlin-Cognato et al. Regional Red List status (2016) Least Concern*† 2007) and morphological (Van Waerebeek 1993a, 1993b) differences: L. o. obscurus in southern Africa, L. o. fitzroyi National Red List status (2004) Data Deficient in southern South America, and an un-named subspecies Reasons for change Non-genuine change: in New Zealand (Perrin 2002). Subspecies classification New information awaits formal description (Cipriano & Webber 2010). Global Red List status (2008) Data Deficient TOPS listing (NEMBA) (2007) None Assessment Rationale Large schools and frequent sightings of Dusky Dolphins in CITES listing (2003) Appendix II both the northern (Namibia) and southern (South Africa) Endemic No Benguela suggest high abundance and more than 10,000 mature individuals.

List of Marine Mammal Species & Subspecies
List of Marine Mammal Species & Subspecies The Committee on Taxonomy, chaired by Bill Perrin, produced the first official Society for Marine Mammalogy list of marine mammal species and subspecies in 2010 . Consensus on some issues was not possible; this is reflected in the footnotes. The list is updated annually. This version was updated in October 2015. This list can be cited as follows: “Committee on Taxonomy. 2015. List of marine mammal species and subspecies. Society for Marine Mammalogy, www.marinemammalscience.org, consulted on [date].” This list includes living and recently extinct (within historical times) species and subspecies, named and un-named. It is meant to reflect prevailing usage and recent revisions published in the peer-reviewed literature. An un-named subspecies is included if author(s) of a peer-reviewed article stated explicitly that the form is likely an undescribed subspecies. The Committee omits some described species and subspecies because of concern about their biological distinctness; reservations are given below. 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 names 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/. Species and subspecies are listed in alphabetical order within families.
