Beaked Whales BEAKED WHALES SCIENTIFIC CLASSIFICATION FAST FACTS FUN FACTS ECOLOGY & CONSERVATION BIBLIOGRAPHY MENU - CETACEA SCIENTIFIC CLASSIFICATION COMMON NAME: Beaked whales, bottlenose whales (genera Hyperoodon and Berardius), ziphiids. KINGDOM: Animalia PHYLUM: Chordata CLASS: Mammalia ORDER: Cetacea SUBORDER: Odontoceti FAMILY: Ziphiidae GENUS SPECIES: 21 Species in 6 genera (listed alphabetically) • Andrews’s beaked whale, Mesoplodon bowdoini • Arnoux’s beaked whale, Berardius arnuxii • Baird’s beaked whale, Berardius bairdii • Blainville’s beaked whale, Mesoplodon densirostris • Cuvier’s beaked whale, Ziphius cavirostris • Gervais’s beaked whale, Mesoplodon europaeus • ginkgo-toothed beaked whale, Mesoplodon ginkgodensis • Gray’s beaked whale, Mesoplodon grayi • Hector’s beaked whale, Mesoplodon hectori • Hubbs’s beaked whale, Mesoplodon carlhubbsi • Longman’s beaked whale (also called Indo-Pacific beaked whale), Indopacetus pacificus • northern bottlenose whale, Hyperoodon ampullatus • Perrin’s beaked whale, Mesoplodon perrini • pygmy beaked whale, Mesoplodon peruvianus • southern bottlenose whale, Hyperoodon planifrons • spade-toothed whale, Mesoplodon traversii • Sowerby’s beaked whale, Mesoplodon bidens • Stejneger’s beaked whale, Mesoplodon stejnegeri • strap-toothed whale, Mesoplodon layardii • Tasman beaked whale, Tasmacetus shepardi • True’s beaked whale, Mesoplodon mirus RETURN TO TOP FAST FACTS DESCRIPTION: Beaked whales, as their name implies, have an obvious beak, or rostrum, of various lengths. 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. Most species only have one pair of teeth in the lower jaw and in most species only males have teeth. The size, shape, and position of these teeth differ between species. In a few species, the teeth are exposed when the mouth is closed. SIZE: Beaked whales are medium to large whales; females are generally larger than males. The largest is Baird’s beaked whale: adult females reach about 12.8 m (42 ft.) and 12,000 kg (26,455 lb.). The smallest is probably the pygmy beaked whale, which reaches about 3.7 m (12 ft.). DIET: Squid and fishes, presumably deepwater species; beaked whales, use suction to bring food into the mouth. The throat grooves of beaked whales aid in suction by stretching to expand the mouth. GESTATION: Estimates not available for most species • Bottlenose whales – 12 months SEXUAL MATURITY: The length at sexual maturity varies throughout species. Reproductive data is not available for most beaked whale species. FEMALE • Gervais’ beaked whale – 4.5 m (14.76 ft.) • Baird’s beaked whale – 10.5 m (34.44 ft.) • Bottlenose whales – 6.7 m (22.64 ft.) MALE • Baird’s beaked whale – 10 m (32.81 ft.) • Bottlenose whales – 7.5 m (24.61 ft.) LIFE SPAN: Varies throughout species; estimates not available for most species • Baird’s beaked whale – 84 years (male) • Cuvier’s beaked whale – 40 to 60 years • Northern bottlenose whale – at least 37 years RANGE: Varies with species • Some species have a cosmopolitan distribution in tropical and cool temperate waters, like Cuvier’s beaked whale. • A few species, like Arnoux’s beaked whale, are circumpolar in the Southern Hemisphere. • Some species have very limited distributions, such as Hubbs’ beaked whale, which is found in the north eastern Pacific Ocean. HABITAT: Beaked whales inhabit offshore waters that are at least 300 m (1,000 ft.) deep. POPULATION: REGIONAL STATUS: IUCN All species listed as Data Deficient with the exception of the following • Baird’s beaked whale, both species of bottlenose whales, and Arnoux’s beaked whale are all listed as Lower Risk/Conservation Dependant. CITES Appendix I USFWS Not Listed RETURN TO TOP FUN FACTS 1. Beaked whale species also are known for deep diving. For Baird’s and Arnoux’s beaked whales, for example, dives to depths of 1,000 m (3,037 ft.) for as long as 45 minutes are not unusual. 2. Researchers theorize that male beaked whales use their teeth only for establishing dominance and for displays of aggression and competition, not for feeding. These interactions leave superficial lacerations which soon heal. Traces of light parallel stripes may remain on the skin. 3. For more information please visit the WHALES infobook. RETURN TO TOP ECOLOGY AND CONSERVATION Few population estimates exist for each beaked whale species.This is due to the fact that they are difficult to find and difficult to identify at sea. Some species are hunted or entangle in gillnets in deep water. Some species, such as Cuvier’s beaked whales, may be vulnerable to certain types of noise which could jeopardize their survival in areas of industrial, military, or recreational activity. Mass strandings in the Mediterranean Sea and the Bahamas have been potentially linked to military exercises involving underwater sound transmissions. Like sperm whales, northern bottlenose whales have spermaceti in their heads, and with their body oil, they were valuable targets for 19th and 20th century whalers. Whaling definitely reduced their abundance in some areas, especially the northeastern Atlantic.

  • 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.
