Adults of both sexes have two pairs of visible teeth that erupt from the front of their lower jaw around sexual maturity. – 18/9/16 ... a giant full 360 spinning breach! Gestation varies greatly between species, lasting 17 months for Baird's beaked whales and 12 months for the northern bottlenose whale. Baird's beaked whales are the largest beaked whales and can grow to just over 11 metres in length, with females just pipping the males as the larger sex. We work with volunteer networks in all coastal states to respond to marine mammal strandings. Series Title: Checkerboard animal library.

Whaleopedia was developed with initial funding from VISA. In the Pacific, we implemented the Pacific Offshore Cetacean Take Reduction Plan to reduce mortalities and serious injuries of several marine mammal stocks—including Baird’s beaked whales—incidentally injured in the California thresher shark/swordfish drift gillnet fishery. The study detected beaked whales in 94 percent of the weeks at the eastern location, and 80 percent of the weeks at the western location. Looking from above, the snout has the appearance of the neck of a bottle, another common name for this whale being giant bottlenose whale. Overall, Species in the beaked whale family are elusive and shy, and often lack easily discernible physical characteristics to distinguish them from one another. The two established species have very similar features and would be indistinguishable at sea if they did not exist in disjoint locations. BAIRD’S BEAKED WHALE Family: Ziphiidae Genus: Berardius Species: B. bairdii Stejneger, 1883 Baird’s beaked whales are very gregarious animals, often found in large groups of 30 or more. In the eastern North Pacific ocean, they can be found north of 28° North to the southern Bering Sea, and in the Western North Pacific ocean from 34° North to the Okhotsk Sea. Typical dives last from 11 to 30 minutes, but beaked whales have been recorded diving for more than an hour; the longest known Baird’s beaked whale dive lasted 67 minutes. They also have a curved head with a bulbous forehead (known as a melon); a distinct, long, cylindrical beak; a curved mouth line; and a crescent-shaped blowhole. NOAA Fisheries estimates the population size for each stock of Baird’s beaked whale in its stock assessment reports. To understand the health of marine mammal populations, scientists study unusual mortality events. IUCN Red List Data Deficient Baird’s beaked whales travel in breeding groups numbering 6-30 members. The distinctive ‘battle teeth’ of the Baird’s beaked whole are surrounded by particularly thick bone, providing the necessary reinforcement during confrontations. Baird’s beaked whales are protected under the Marine Mammal Protection Act. Photo: NOAA Fisheries/Robert Pitman.

Baird’s beaked whale: dark brown, with irregular white patches on the belly The lower jaw is longer than the upper and the front teeth are visible even when the mouth is fully closed, forming so called ‘battle teeth’. When stranded animals are found alive, NOAA Fisheries and its partners assess the animal’s health and try to return it to the water. Increasing evidence suggests that exposure to intense underwater sound in some settings may cause some whales to strand and ultimately die. Beaked whales have shown behavioral responses to sonar and are thus susceptible to the impact of military activity in the area. Baird's beaked whales in the Aleutian Islands. Baird's beaked whales are one of the beaked whales to be most commonly sighted within their range, due to their large size and gregarious behavior. The Baird's and Arnoux beaked whales in the family Ziphiidae are the only whales in this family that both sexes have erupted teeth. Once entangled, whales may drag and swim with attached gear for long distances, ultimately resulting in fatigue, compromised feeding ability, or severe injury, which may lead to reduced reproductive success and death. Baird’s beaked whales are deep-diving cetaceans which belong to a group called the ‘beaked whales’, named for their elongated beaks. Their key distinguishing feature is the presence of a 'beak', somewhat similar to many dolphins.Other distinctive features include a pair of converging grooves under the throat, and the absence of a notch in the tail fluke. Information from this research can be used in management actions to protect these animals. There is no precise data about this whale’s mating system, but they occur in groups with a number of males, and in large groups with both male and female adults. For all other beaked whale species studied, the oldest recorded age is between 27 and 39 years. Beaked whale species can be difficult to distinguish from one another because many have a similar appearance.

With declining numbers and emphasis on other species, the number of B. bairdii caught has diminished (Watson, L. 1981). The gestation period is probably around 12 months, though they have been reported up to 17 months, and a single calf is born. The scars on these leaders' beaks and backs indicate aggression and rivalry for such a position. , an unusual mortality event (UME) is defined as "a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response.". These whales are among the least studied and most mysterious of all cetacean families. The Alaska and St. George Island whales were 6.6 and 7.3 metres long, suggesting their species is a little bit smaller than a Baird's beaked whale, whose adult males average 10 metres.
