Although M. carlhubbsi is not considered endangered or threatened by the U.S. governement, this species is still protected by U.S. laws and regulations.
Cetaceans fall under the responsibility of the National Marine Fisheries Services. This is a category under the Department of Congress.
According to the National Environmental Policy Act of 1969 (NEPA), there are major implications with regard to noise and its effects on marine mammals. Studies of noise effects have been done to provide the data needed for impact statements in regards to its effects on marine mammals. NEPA is the U.S. legislation under which Environmental Assessments and Impact Statements are required.
The U.S. Marine Mammal Protection Act of 1972 (MMPA) promotes the conservation of marine mammal populations and their habitats. They established a stand on the “taking of marine mammals.” “Taking” can be defined as including harassment as well as hunting, capturing, and killing. There are some exceptions to “taking”, however. It is allowed during scientific research as long as a scientific research permit is obtained. Also excused is the unintentional harassment of small numbers of marine mammals by human activities. An incidental take authorization must be obtained in this case.
In 1994, amendments were made to the MMPA. Harassment was defined as “any act of pursuit, torment, or annoyance which has the potential” to a) “injure a marine mammal or marine mammal stock in the wild,” or b) “disturb a marine mammal or marine mammal stock in the wild by causing disruption of behavioral patterns including, but not limited to, migration, breathing, nursing, breeding, deeding, or sheltering.”
Specifically, because of the limited scale of which Mesoplodon species are directly taken, and the “lack of effect that any kind of regulation would have on these kinds of subsistence fisheries,” there has been no known effort to regulate the take of these animals.
No information has been found regarding predation in M. carlhubbsi.
Generally, the whales in the genus Mesoplodon are small. The maximum adult length ranges from 4.3 meters to 6.15 meters. Males of this species can reach a maximum weight of 1500 kg. These whales have relatively small heads, large thoraxes and abdomens, and short tails (as compared to other toothed whales).
Mesoplodon species also have a pair of throat grooves. These are found on the ventral side of the head between the lower jaws. A notch occurs in the center of the flukes. The flipper has a short phalangeal portion. This is typical of the family Ziphiidae. The dorsal fin is small and sub-triangular. It is positioned about two-thirds of the way back on the animal.
Adult male M. carlhubbsi are usually dark gray to black except for two white patches on the head. One patch covers the tip of the rostrum and lower jaw back to the posterior border of the teeth. The other patch occurs in a roughly circular pattern, about 30 centimeters in diameter, centered around the blowhole.
The functional teeth in males are large and straight-sided. They are located near the middle of the mouth. These remain exposed when the mouth is closed.
Adult female M. carlhubbsi are usually medium-gray on the dorsal surface of their bodies. Their sides are a lighter shade of gray. The belly is white. Also, the area of the body just posterior to the flipper, termed the flipper pocket, is darker in color than the surrounding body. The front half of the rostrum and lower jaw are lighter in color than the rest of the head.
The functional teeth of females are smaller than those of the males. They often don’t erupt above the gums.
In both sexes of M. carlhubbsi, the bottom side of the flukes is lighter than the top side. They also have concentric striations that radiate anteriorly from the terminal caudal vertebrae.
Range mass: 1500 (high) kg.
Average mass: 1500 kg.
Range length: 4.3 to 6.15 m.
Sexual Dimorphism: sexes colored or patterned differently; male more colorful
Other Physical Features: endothermic ; bilateral symmetry
No data has been found regarding the lifespan, or longevity, of M. carlhubbsi. This paucity of data is common for the genus.
M. carlhubbsi seems to prefer deep water far from shore. Their typical habitat is the deep, subarctic current system.
Habitat Regions: temperate ; polar ; saltwater or marine
Aquatic Biomes: pelagic
Mesoplodon carlhubbsi, or Hubb’s beaked whale, is found in the temperate waters of the North Pacific. M. carlhubbsi ranges from Japan to British Columbia and California. The northernmost sighting occurred in Eastern North Pacific, near Prince Rupert, British Columbia. The southernmost record occurred southwest of San Clemente Island, California. Here, a rostral portion of a skull was found by the submersible “Deep Sea.”
Biogeographic Regions: pacific ocean (Native )
The diet of M. carlhubbsi includes squid, other cephalopods, and fish. According to Ridgway and Harrison (1989), it is believed that M. carlhubbsi feeds mainly on squid, which is characteristic of beaked whales. However, all information is based on stranded animals. It is possible that the stranded individuals might not be representative of the whole population.
Animal Foods: fish; mollusks
Primary Diet: carnivore (Piscivore , Molluscivore )
No information has been found regarding the ecosystem roles of M. carlhubbsi. However, it is likely that as large marine predators, these whales have some regulating influence on their prey populations, primarily fish and squid.
Very small numbers of M. carlhubbsi are taken by commerical fisheries.
Positive Impacts: food
No information has been found regarding any negative economic impact of this species on humans. It is unlikely that there is even much interaction between humans and this species, as M. carlhubbsi is typically found far from shore in deep waters.
There is not much data available on the development of Mesoplodon carlhubbsi. The mean length at birth is estimated to be 2.50 meters for M. carlhubbsi. However, this is based on extrapolation as 40-48% of the maximum reported length of females in the species. (Ridgway 1989). M. carlhubbsi can reach a maximum length of about 530 cm along with an average of about 1500 kg. (Nowak 1991).
It is difficult to evaluate the population size of species like M. carlhubbsi, because they occur far from shore, and because they are not very conspicuous animals. Although they are sighted infrequently, as are most members of the genus, it is difficult to tell whether the low incidence of sightings is due to rarity of animals, or is simply an artifact of their unobtrusive behavior in a remote habitat.
However, all species of Cetacea are listed by CITES as being on Appendix II unless listed on Appendix I. This places all Mesoplodon species on Appendix II.
US Federal List: no special status
CITES: appendix ii
IUCN Red List of Threatened Species: data deficient
Most odontocete whistles are narrowband sounds. The frequency pattern can be unmodulated, trilled, ascending, descending, ascending-descending, descending-ascending, or slowly wavering. A whistle can consist of one of these sound patterns that is given once or repeated. It can also consist of a series of sounds of several types. The amplitudes of the ascending and descending portions can vary over the duration of a whistle. Whistles can have a varying number of breaks and segments in one whistle or be continuous. The initial, final, maximum and minimum frequencies, as well as the duration and level, may vary for any one species.
M. carlhubbsi produces pulses and whistles to communicate. Their typical frequency range for pulses are 0.3-2, 0.3-80+ kHz, with the dominant frequencies occurring in the range of 0.3-2 kHz. The typical frequency range for whistles is 2.6-10.7 kHz.
In addition to vocal communication, it is likely that M. carlhubbsi, like other mammals, uses both visual and tactile signals.
Communication Channels: visual ; tactile ; acoustic
Perception Channels: visual ; tactile ; acoustic ; chemical
The mating system of these whales has not been characterized in the literature.
There is not much data available on reproduction in M. carlhubbsi. Birth usually occurs during the summer, after a twelve month gestation. According to Reynolds and Rommel (1999), “The timing of events in the reproductive cycle for all cetaceans is clearly geared to optimize the seasonal changes in environmental conditions to benefit the ecology of the species and favor maximal survival of the young."
The litter size is most likely one offspring per birth in the entire genus Mesoplodon. Young are likely precocial, and able to follow the mother from birth.
There are no data available on the timing of weaning, independence, or reproductive maturity for this species.
Breeding interval: The breeding interval for these whales is unknown, but is certainly no more than once per year.
Breeding season: Breeding probably occurs in the summer.
Average number of offspring: 1.
Average gestation period: 12 months.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (Internal ); viviparous
Young are most likely precocial and able to follow their mother through the water from birth. As in all mammals, the mother provides milk for the developing young, although the period of nursing in this species is not known. It is not known what role males may play in parental care.
Parental Investment: precocial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female)

Der Hubbs-Schnabelwal (Mesoplodon carlhubbsi) gehört zur Gattung der Zweizahnwale (Mesoplodon) innerhalb der Familie der Schnabelwale (Ziphiidae). Die Art wurde 1963 beschrieben und nach dem US-amerikanischen Meeresbiologen Carl Hubbs benannt.
Hubbs-Schnabelwale leben im nördlichen Pazifik zwischen dem 30. und 50. Breitengrad. Strandungen sind von den Küsten Japans, Kanadas und den USA belegt, auch eine Sichtung lebender Tiere auf hoher See ist bekannt. Die Männchen dieser Walart sind einheitlich dunkelgrau bis schwarz gefärbt, nur die leicht gewölbte Stirn und die Schnauze sind weiß. Weibchen und Jungtiere sind heller und haben eine weißliche Unterseite. Bei den Männchen ragen darüber hinaus zwei Zähne des Unterkiefers aus dem hinteren Teil der Schnauze. Diese Tiere erreichen eine Maximallänge von 5,3 Metern und ein Gewicht von bis zu 1500 kg.
Diese Wale sind Bewohner des offenen Meeres und kommen selten in die Nähe der Küsten. Zahlreiche Narben am Rücken und an den Flanken der männlichen Tiere deuten auf ausgeprägte Rivalenkämpfe hin. Wie die meisten anderen Zweizahnwale dürften sie in Paaren oder kleinen Gruppen zusammenleben und lange und tief tauchen. Ihre Nahrung besteht zum überwiegenden Teil aus Tintenfischen.
Sehr wenige Exemplare dieser Walart werden von japanischen Walfängern gejagt, aufgrund ihres seltenen Auftretens spielten sie in diesem Wirtschaftszweig nie eine große Rolle. Angaben über Population oder Gefährdung lassen sich aufgrund der zurückgezogenen Lebensweise nicht machen, Hubbs-Schnabelwale gelten jedoch als selten.

Hubbs' beaked whale (Mesoplodon carlhubbsi) was initially thought to be an Andrews' beaked whale when discovered by ichthyologist Carl Hubbs; however, it was named in his honor when it was discovered to be a new species. This species has the typical dentition found in the genus, but its main outstanding features are a white "cap" on the head and very extensive scarring. The species is known from 31 strandings, a few at-sea sightings, and observations of two stranded whales that were kept in captivity for 16-25 days.
Carl Leavitt Hubbs, a noted American ichthyologist, published a description of a whale found alive in the surf near his office at the Scripps Institution of Oceanography in La Jolla, California, in 1945. He believed it to be Andrews' beaked whale (a very similar species found only in the Southern Hemisphere), but Joseph Curtis Moore, an expert on beaked whales at Chicago's Field Museum, reassigned it to a new species, Mesoplodon carlhubbsi, in 1963, naming it in his honor.[3]
Hubbs’ beaked whale M. carlhubbsi has a light ventral surface and a midventral portion grading from white to medium gray dorsally. The dorsal surface of the flipper is slightly darker than the adjacent thorax in adult females, with a faint light patch on the distal posterior edge. However, the light patch is more noticeable in adult males. The head of adult male M. carlshubbsi is the most striking feature- black with naturally white areas on the tip of the rostrum and anterior to the blowhole. For females, the tip of the rostrum is distinctly lighter than the rest of the head. Males also have a strong pair of teeth protruding from the mandibular symphysis.
It is estimated M. carlhubbsi are along the coast of Japan and Pacific coast of North America. The distribution along North America extends from San Diego to Prince Rupert. Southern limit is unknown but the northern limit is Vancouver Island. Distribution is probably not directly related to the character of the water mass but rather follows the distribution of the prey species it feeds on. M. carlshubbi follows prey items in intermediate and deep-water masses, rather than surface water masses.
Stomach contents of stranded M. carlhubbsi contained squid beaks, fish otoliths, and fish bones. Prey species included Gonatus sp., Chauliodus macouni, Icichthys lockingtoni, and Poromitra crassiceps. Researchers assume calving takes place in the summer based on lengths of neonatal specimens, gestational period, and fetal growth in most cetaceans. On October 3 they found a 90 cm fetus which had about 160 cm of growth before birth which gives an estimated time of birth of about mid-May. A few acoustic and other behavioral observations were made of stranded M. carlhubbsi when they were held briefly in captivity. A stereotyped beaked whale echolocation pulse type (termed BW37V) is thought to be made by this species but has not been linked to a sighting, so this attribution is considered provisional.
The species has been occasionally killed by Japanese whalers and has been caught in driftnets off California. Recent strandings in Hawaii have occurred, supporting the theory of open ocean habitation by this species. Threats include fishing and harvesting of aquatic resources, pollution, and climate change. M. carlhubbsi are occasionally taken by Japanese whalers and small cetacean fisheries. Incidental catches in drift gillnets occur sporadically off the coast of California. Climate change and severe weather may cause M. carlhubbsi to shift habitat. Also, as with most beaked whales, they may be vulnerable to loud anthropogenic sounds, especially those generated by navy sonar and seismic exploration.

Il mesoplodonte di Hubbs (Mesoplodon carlhubbsi) è un cetaceo odontoceto della famiglia Ziphiidae. Quando venne scoperto dall'ittiologo Carl Hubbs, venne erroneamente ritenuto un mesoplodonte di Bowdoin; comunque, non appena lo studioso si accorse di aver scoperto una nuova specie, venne ribattezzata così in suo onore. Questa specie ha la tipica dentatura bizzarra che si ritrova tra i membri del suo genere, ma le sue caratteristiche più salienti sono un "berretto" bianco sulla testa e cicatrici molto numerose. Questa specie è nota per 31 spiaggiamenti ed un possibile avvistamento.
Il corpo è quello tipico dei Mesoplodon, fatta eccezione per un aspetto più rotondo e più affusolato alle estremità, cosa che le dà l'aspetto di un fuso. Il rostro ha una lunghezza moderata e la mandibola inferiore si inarca oltre il rostro, come nel mesoplodonte di De Blainville, ma molto meno. I denti sono abbastanza lunghi, sono situati all'apice della mandibola e sono leggermente più alti del rostro. Dopo i denti, la mandibola scende giù per ritornare al pari del becco. I maschi hanno una colorazione che va dal grigio scuro al nero, senza controombreggiatura, possiedono macchie bianche sul becco e sul melone bulboso (simile ad un cappello "da baseball") e presentano anche estese cicatrici bianche. Le femmine e i giovani hanno il dorso di un grigio più chiaro e le regioni inferiori bianche e a volte hanno bianco anche il becco. Sia i maschi che le femmine raggiungono una lunghezza di 5,4 metri e pesano 1500 kg. Alla nascita sono lunghe circa 2,5 metri, le dimensioni più lunghe di ogni balena dal becco: il 46% della lunghezza della madre.
Vive nel Pacifico settentrionale, ad ovest è limitata al Giappone e ad est è diffusa dalla Columbia Britannica alla California. Tra queste due aree dovrebbero vivere anche nell'oceano aperto, ma non è mai stata fatta alcuna osservazione. A causa delle piccole dimensioni del loro areale, dovrebbe essere raro, ma non sappiamo con certezza a quanto ammontino le sue popolazioni.
A causa dell'infrequenza degli avvistamenti (solamente uno) conosciamo poco del loro comportamento, ma probabilmente viaggiano in piccoli gruppi come le altre specie. Dal grande numero di cicatrici presenti sui maschi adulti si ritiene che i maschi di questa specie siano più in competizione degli altri membri del genere. Si pensa che si nutrano di calamari.
Questa specie è stata uccisa occasionalmente dai balenieri giapponesi ed è rimasta intrappolata in reti da pesca al largo della California.

Bågnäbbval (Mesoplodon carlshubbi[2][3][4][5][6][7][8][9]) är en näbbval som tillhör släktet Mesoplodon.[10][11] Ursprungligen antogs den vara en Andrews näbbval när den upptäcktes av iktylogen Carl Hubbs, och den namngavs till hans ära när man upptäckte att det var en ny art. Den här arten har den typiska, bisarra tandbildningen som är gemensam för släktet, men det som är utmärkande för arten är en vit "mössa" på huvudet och väldigt omfattande ärrbildning. Bågnäbbvalen har setts stranda 31 gånger och har möjligen siktats en gång.
IUCN kategoriserar arten globalt som otillräckligt studerad.[1]
Kroppen är ganska typisk för en Mesoplodon, förutom att den är mer knubbig ut i utseendet, och kroppen smalnar av vid slutet i en slags sländform. Näbben är av måttlig längd, och underkäken välver sig över nosen, i likhet med Blainvilles näbbval men mindre överdrivet.
Tänderna är ganska stora och sitter överst på käken, och är en aning högre än framdelen (nosen). Efter tänderna sluttar käken ner till att forma en annars typisk näbb. Färgsättningen hos hanar är mörkgrå till svart, med vit undersida, med vita fläckar på näbben (på den svällda melonen), och kroppen har en omfattande ärrbildning som också kan vara vit. Honor och juveniler är ljusare grå ovan och undersidan är vit, och ibland har de även vitt på näbben. De når en längd på 5,4 meter och både hanar och honor väger 1500 kg. När de föds är de runt 2,5 meter långa, den längsta proportionen av någon annan näbbval: 46% av moderns längd.
Valen lever i norra Stilla havet. I öst sträcker den sig till Japan och i väst går den från British Columbia till Kalifornien. De lever möjligen på öppet hav mellan de två områdena, men inga observationer av arten har gjorts där. Beroende på deras förmodade lilla utbredningsområde kan de vara sällsynta, men inget är säkert känt om hur stor populationen egentligen är.
Lite är känd om deras beteende på grund av de få siktingar som har gjorts (bara en är känd), antagligen rör de sig i små grupper som de andra arterna. På grund av den extrema mängden ärr som finns på vuxna hannar är det troligen mer manlig tävlan jämfört med andra medlemmar av släktet. De antas leva på bläckfisk.
Arten har stundtals dödats av japanska valfångare och har fångats i drivnät vid Kalifornien. Strandningar i Hawaii har nyligen förekommit, vilket stödjer teorin om att arten habiterar på öppet hav.

Из-за строения зубов его путали с командорским ремнезубом, и только в 1963 году американский зоолог Дж. Мур выделил новый вид, указав его чёткие различия — две пары выемок в основе рострума на черепе.
哈氏中喙鯨或胡氏中喙鯨（學名Mesoplodon carlhubbsi）旧称哈氏喙鲸，又称弧喙鲸。僅分布於北太平洋。1945年，在美國加州拉賀亞海灘（La Jolla）曾有1頭喙鯨擱淺，美國著名的魚類學家Carl Hubb對此發表了1篇描述報告，當時他認為那是安氏中喙鯨；不過芝加哥自然史博物館（Field Museum of Natural History）的哺乳動物學家與喙鯨專家Joseph Curtis Moorebe並不這麼認為，經他再次鑑定後確立此樣本為1新種喙鯨，種名carlhubbsi即為他對同僚表達的敬意。

胡氏中喙鯨的體型中段粗壯，往身體兩端漸細。背鰭略呈鐮刀形，位於身體中部後方，成鯨背鰭約22-23公分高。額隆呈中等球狀，嘴部曲線後半明顯拱起，成年雄鯨外露的牙齒即位於下顎最高處。成年雄鯨的體色普遍呈暗灰至黑色，在上、下顎大部分與額隆有白色區域。噴氣孔周圍有直徑可達30公分的大型白斑，其形狀多變，外觀上容易讓人聯想到白色帽子，或無邊扁帽（beanie，像風帽狀的圓形無邊帽）。成年雄鯨在側腹與腹部有許多傷痕。雌鯨與未成年雄鯨的體色呈漸層變化，由背部灰色、側腹淺灰，直到腹部的白色。其嘴喙顏色明顯較身體為淺，但不及成年雄鯨般亮白。
胡氏中喙鯨已知僅分布於北太平洋溫帶海域。在北太平洋西部，此物種似乎侷限在日本本州的東北部海岸，約在北緯38度親潮與黑潮交會處。在北太平洋東部，其分布北限一般認為在加拿大的卑詩省（約北緯54度），最南至加州的聖地牙哥（約北緯33度）。其分布情形似乎與深層海流有關。
成年雄鯨身上的傷痕有隨著年齡增長而增加的現象，雖然有另外數種喙鯨亦具此特徵，但胡氏中喙鯨特別的地方在於，其成年雄鯨全身幾乎全被白色傷痕覆蓋。這些傷痕似乎是其他雄鯨用牙齒造成，可能與社會地位或生殖等的競爭行為有關。另外，牠們的身上也有長條單獨或成對的擦傷痕跡。胡氏中喙鯨主要以海洋中層的魷魚和魚類為食。對於其生殖狀況幾乎一無所知，推測可能在夏季生產。
胡氏中喙鯨的族群數量不明。日本漁民在捕捉柯氏喙鯨與小型海豚時偶爾會獵殺牠們。牠們在加州常因流刺網而死亡，可能在其他地區也有同樣的情況，可能已造成局部區域的數量減少。牠們的分布似乎有特定地域性，使其對環境變化的因應能力相當脆弱。

ハッブスオウギハクジラ（ハッブス扇歯鯨、Mesoplodon carlhubbsi）はハクジラ亜目アカボウクジラ科オウギハクジラ属に属するクジラである。 魚類学者カール・ハッブス (Carl Hubbs) によって発見された時にはタイヘイヨウオウギハクジラであると考えられたが、後に新種であることが示された。種小名 carlhubbsi はこのハッブスの名前に由来する。
座礁により確認されている個体は31頭が知られており、野生下での目撃例は1例だけ報告されている。
ハッブスオウギハクジラの体型はオウギハクジラ類としては典型的であり、比較的丸っこく、先細りの紡錘形である。口吻の長さは平均的である。コブハクジラのように下顎の一部が上顎からはみ出たフェンス状になっているが、コブハクジラほどは極端ではない。
歯生はオウギハクジラ属としては典型的であり、雄は上顎には歯はなく、下顎に2本だけ長い歯を有しており、口外に露出している。雌の場合には全ての歯は歯茎に隠れている。 ハッブスオウギハクジラの特徴は頭部に帽子のような白い模様と全身の傷である。
雄の体色は全身が濃い灰色あるいは黒であり、腹側に明るい色を持たない。口吻と頭部のメロン付近は白く、体表に多くある傷も白い。雌や未成熟の個体は背側は明るい灰色で、腹側は白い。
体長は5.4m、体重は1,500kgに達する。生まれた直後の体長は2.5mであり、母親の体長の46%に相当し、オウギハクジラ類の中で最も大きな比率である。
ハッブスオウギハクジラは北太平洋に生息する。西側は日本付近、東側はブリティッシュコロンビア州からカリフォルニア州にかけての海域に生息することが知られている。その中間の海域にもおそらく生息すると考えられるが、目撃例は報告されていない。推測されている生息域は狭いため、生息数は多くはなく珍しい種であると考えられるが、全生息数は不明である。
野生下での目撃例は1例が知られているのみで乏しいため、生態は不明であるが、おそらく他のオウギハクジラ類と同様に小さな群を成して行動すると思われる。 成体の雄の体表には同種の雄と争ってできた傷が多数あるため、他のオウギハクジラ類よりも同種の雄同士の争いが頻繁に行われていると考えられる。 主にイカを食べると考えられている。
日本では時々捕鯨船によって捕獲されることがある。 カリフォルニア沖では流し網による混獲の犠牲になることが知られている。

허브부리고래(Mesoplodon carlhubbsi)는 부리고래과 이빨부리고래속에 속하는 고래의 일종이다.[2] 어류학자 허브(Carl Hubbs)가 처음 발견했을 당시에는 앤드류부리고래의 일종으로 생각했다. 그러나 신종으로 등록되면서 허브의 이름을 따서 명명하였다.
