List of Marine Mammal Species and Subspecies

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 version was updated on 3 April 2012.

This list can be cited as follows: “Committee on Taxonomy. 2012. 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/.

Based on molecular and morphological data, 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, Price et al., 2005; Agnarsson and May-Collado, 2008)1. Below the rank of order, we list only families, species and subspecies, omitting superfamilies, subfamilies and taxa of other ranks.

For pinnipeds we follow Berta and Churchill (2011). To avoid issues of paraphyly, these authors proposed that based on data from genetics and morphology the genus Arctocephalus be limited to Arctocephalus pusillus, the type species of the genus Arctocephalus, and transferred the remaining 'Arctocephalus' species (i.e. A. australis, A. galapagoensis, A. gazelle, A. philippii and A. tropicalis) to Arctophoca Peters, 1866. Four subspecies of Arctophoca australis are listed: A. a. australis, A. a. forsteri, A. a. gracilis and A. a un-named. Two subspecies of Arctophoca philipii are valid: A.p. philippii and A. p. townsendi, although small sample sizes and a small number of genes sampled are concerns. Two subspecies of Eumetopias are supported largely on genetic data, which is also the case for recognition of California, Japanese and Galapagos sea lions as separate species. Brunner (2004) advised use of Otaria byronia (Blainville, 1820) over O. flavescens (Shaw, 1800).  Lindqvist et al. (2009) concluded that a purported third subspecies of walrus Odobenus rosmarus laptevi is not valid. Recent genetic analyses indicate that Phoca vitulina concolor is paraphyletic and this along with lack of morphological differentiation suggests that the western Atlantic subspecies is not valid; P. v. vitulina is considered here to apply to all Atlantic harbor seals. Within the North Pacific, until the subspecies limits of various populations are assessed only a single subspecies is recognized, Phoca vitulina richardii. Placement of the ringed seal, Caspian seal and Baikal seal has alternated between the genera Phoca and Pusa. We accept Rice's (1998) use of Pusa as the correct classification." The use of Lontra rather than Lutra for the marine otter follows Larivière (1998) in rec­ognizing the otters of North and South America as a monophyletic taxon distinct from the otters of Eurasia.

In the mysticete cetaceans, recent genetic evidence strongly supports the recognition of three separate phylogenetic species of right whales (Rosenbaum et al., 2000; Gaines et al., 2005). In addition, the genus Eubalaena (rather than Balaena as in Rice, 1998) is retained for the right whales as recommended by the Scientific Committee of the International Whaling Commission (IWC, 2002)2. All Bryde's whales are provisionally considered to comprise a single species, Balaenoptera edeni, following the usage of the IWC (IWC 2002, 2008) and Kato and Perrin (2009). Some workers recognize B. edeni as including only the small-form coastal Bryde's whales of the western Pacific and Indian Oceans, using B. brydei for the globally distributed larger more oceanic form (Sasaki et al., 2006). Kato and Perrin (2009) consider these more likely to be distinct at the subspecific level, and they are included here as such. Balaenoptera omurai is a newly described species (Wada et al., 2003). It was previously confounded with the Bryde's whale and has been confirmed as having a separate and ancient lineage (Sasaki et al. 2006). Clarke (2004) proposed recognition of a pygmy form of the fin whale as a subspecies, based on distribution, size and coloration. He resurrected the synonym patachonica Burmeister, 1865 to apply to the subspecies: B. physalus patachonica.

In the odontocetes, Mesoplodon traversii (spade-toothed whale) has been recognized as the senior synonym for M. bahamondi (Bahamonde's beaked whale) (van Helden et al., 2002). Mesoplodon perrini is a newly described species (Dalebout et al., 2002).  The species Inia boliviensis d'Orbigny 1834 of the Cochabamba, Santa Cruz, Beni and Pando areas of the Bolivian Amazon basin is included in accordance with prevailing usage (Ruiz-García and Shostell, 2010). While the two Inia species overlap in all morphological characters (da Silva, 1994; Ruiz-García et al., 2006), they have been reproductively isolated from each other by a long series of rapids for an estimated 3.1 million years (Hollatz et al., 2011), and two independent lines of genetic evidence, from mtDNA and nuclear introns (Banguera-Hinestroza et al., 2008; Ruiz-García et al., 2008) suggest that they are on separate evolutionary trajectories and deserve recognition as phylogenetic species. Robineau et al. (2007) described the subspecies Cephalorhynchus commersonii kerguelenensis, and A. Baker et al. described C. hectori maui. We follow the IWC in listing only two species of Sousa; the taxonomy of this group is in flux (Parra and Ross, 2009). The tucuxi has been split into the freshwater Sotalia fluviatilis (retaining the common name tucuxi) and the marine Guiana dolphin S. guianensis (Caballero et al. 2007).  The Burrunan dolphin Tursiops australis, recently described by Charlton-Robb et al. (2011), is not included here; its validity is uncertain. Among potential problems relating to its putative species status:

  1. the specimens were compared morphologically only with bottlenose dolphins from Australia,
  2. despite the small sample sizes, the series overlapped in all metric characters and separation was possible only with multivariate analysis (which commonly resolves geographical forms within a species, e.g see Perrin et al. (1999) and Perrin et al. (2011) for Stenella longirostris and Tursiops truncatus, respectively),
  3. comparisons of external morphology and non-metrical characters were made only with T. truncatus, to the exclusion of T. aduncus,
  4. support for important nodes in molecular trees suggesting phylogenetic separation was low.

A rigorous re-evaluation of the relevant data and arguments is needed.Recognition of the Black Sea bottlenose dolphin is now well-supported by genetic data (Viaud-Martinez et al., 2008), as is the Black Sea common dolphin (Natoli et al., 2008). Delphinus tropicalis is now considered a subspecies of D. capensis (Jefferson and Van Waerebeek, 2002). Lagenorhynchus is widely considered an unnatural (polyphyletic) taxon containing morphologically convergent species (Cipriano 1997, LeDuc et al. 1999, McGowen 2011), and application of the genera Sagmatias (for L. obscurus, obliquidens, australis and cruciger) and Leucopleurus (for L. acutus) have been suggested as appropriate and used by some workers. However, there is continuing disagreement about whether australis and cruciger should be included in Cephalorhynchus (which would necessitate a new genus for obliquidens and obscurus, as australis is the type species for the genus Sagmatias) and about whether albirostris and acutus are sister species (which would obviate the need for Leucopleurus). We therefore provisionally retain all the species in Lagenorhynchus. Harlin-Cognato (2010) recognized L. o. posidonia (Peru/Chile). She also recognized L. o. superciliosis (Lesson and Garnot, 1826) for the New Zealand subspecies, but the species identity of the figure in Lesson and Garnot is in question, and we retain use of "un-named New Zealand subspecies." Perrin et al. (1999) established the subspecies Stenella longirostris roseiventris. The Irrawaddy dolphin was recently split into O. brevirostris and O. heinsohni, the Australian snubfin dolphin (Beasley et al., 2005). Krahn et al. (2004) recognized two un-named species of killer whales, the resident and transient forms.Wang et al. (2008) and Jefferson and Wang (2011) established Neophocaena asiaeorientalis as a full species, with two subspecies. Viaud-Martinez et al. (2007) concluded based on morphological and genetic evidence that Phocoena phocoena relicta is a valid subspecies.

In the Sirenia, subspecies of the dugong are not currently recognized (Domning, 1996). However, no in-depth study has been undertaken to address the issue of subspecies.

For review of species concepts, see Reeves et al. (2004), Orr and Coyne (2004), de Queiroz (2007) and Perrin (2009).  Perrin et al. (2009) reviewed the cetacean subspecies, but that review has not yet appeared in the peer-reviewed literature and is therefore not considered here; the subspecies (including for the Carnivora and Sirenia) are as recognized by Rice (1998), with the above-noted changes.

Corrections and comments should be directed to the Ad Hoc Committee on Taxonomy (william.perrin@noaa.gov).  Divergent opinions by members of the Committee on particular taxonomic questions are given in the footnotes.

Footnotes

1Use of Order Cetartiodactyla is favored by most evolutionary mammalogists working with molecular data. Some others, including many marine mammalogists and paleontologists, favor retention of Order Cetacea in the interest of taxonomic stability.

2(from D. Rice) Baker et al. (2003) hold that there is no evidence that would support the classification of the right whales as more than a single biological species.  [The three species are here recognized as phylogenetic species.]
