Although they were easy targets for whalers long ago and currently face threats from human-caused noise, northern bottlenose whales in the United States are not endangered or threatened. Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. We work with volunteer networks in all coastal states to respond to marine mammal strandings. We study the basic acoustic behavior of cetaceans and fish, mapping the acoustic environment and finding better ways to find cetaceans using acoustic technologies. Northern Bottlenose Whales were heavily hunted around the early 1900s. Targeted by whalers throughout the 19 th and 20 th centuries, over 65,000 northern bottlenose whales lost their lives. For the last several decades, northern bottlenose whales have remained unexploited, except for the animals killed in the Faroe Islands drive fishery. The slope of the forehead becomes extremely steep and the surface becomes flattened (like the end of a barrel) in mature males. Males are known to be combative, using their large heads to hit one another. Hyperoodon (or Hyperoödon ) [2] is a genus of beaked whale , containing just two species: the Northern and Southern bottlenose whales . The beak of this whale is very similar to that of a dolphin. It can be found off the east coast of North America from Davis Strait to New York. In terms of color these whales have a gray to dark gray skin tone with a lig… The Northern Bottlenose Whale, Scotian Shelf population (NBW-SSP) was listed as Endangered under the federal Species at Risk Act in 2006. NOAA Fisheries conducts research cruises to collect information on beaked whale stocks, such as habit preferences and feeding ecology. Not thought to be particularly migratory, northern bottlenose whales are found in the cooler waters of the North Atlantic Ocean: from New England all the way to southern Greenland in the west, and from the Strait of Gibraltar right up to Svalbard in the east. Alongside their bodies they have small, pointed flippers that help them with manoeuvrability. While at the ocean surface, northern bottlenose whales produce fairly small, bushy blows every 30 to 40 seconds that are about 3.3 feet tall and visible from a significant distance. Sporting rich chocolate, olive brown and grey tones on their bodies, their heads become lighter in shade whilst their crescent-shaped dorsal fins are darker. As adults, northern bottlenose whales can reach lengths of approximately 36.7 feet and weigh up to 16,534 pounds. Choosing to stay by the sides of wounded companions, whales were easily picked off one by one. They have a distinctive, bulbous forehead (known as a melon) that is lighter in color and a well-defined, bottle-shaped beak; however, these characteristics may vary with sex and age. The dorsal side is darker than the ventral side, giving it a counter-shading appearance. Educating the public about the threats beaked whales face. While diving, they feed near the ocean bottom mostly on deep-sea cephalopods (e.g., squid), fish (e.g., herring), shrimp, sea cucumbers, and sea stars. Not unusual for some populations to take up residence in a certain area, some groups of northern bottlenose whales have been researched in more detail, for example those in the 'Gully' canyon off Nova Scotia. The northern bottlenose whale (Hyperoodon ampullatus) is found only in the North Atlantic, primarily in offshore waters deeper than 500 metres. The Scotian Shelf population is a year-round resident, with a high population density in the Sable Gully. Mostly found in pods of between 4 and 20 whales, they have a primarily fission-fusion social structure. Sexual maturity is reached at the age of 8-14 years (female) and 7-9 years old (male).The gestation lasts about 12 months. NOAA Fisheries is working to conserve this species to ensure populations remain stable. Most easily recognised by their large foreheads, they have bulbous melons which are particularly pronounced in older males. To understand the health of marine mammal populations, scientists study unusual mortality events. Northern bottlenose whales are usually found individually or in social groups averaging between four and ten individuals, but they have been occasionally seen in larger groups and loose aggregations of up to 50 animals. Whalers exploited the curiosity and social bonds of these animals, which were often attracted to stationary vessels and stayed with wounded or injured members of their pod. When stranded animals are found alive, NOAA Fisheries and its partners assess the animal’s health and try to return it to the water. Often approaching boats, they are happy to remain in the company of onlookers for some time before carrying on their way again. Northern bottlenose whales, however, are the most extensively studied of the beaked whales because they used to be heavily hunted, making carcasses available for scientists to examine.

The Northern bottlenose whale (Hyperoodon ampullatus) is a robust, medium-sized whale with a distinctive bulbous melon or forehead; which is relatively much larger in males than in females. Fishermen discovered spermaceti (a waxy substance used in oil lamps, lubricants, and candles) in northern bottlenose whales in the 1850s, which started a commercial whaling fishery for the species. Scientists have conducted long-term studies of a resident group off of Nova Scotia, Canada (a large submarine canyon called the “Gully”), and strandings have occurred in the Baltic Sea, Bay of Fundy, and Rhode Island. At birth, calves measure around 3 meters in length. Greenock Coastguard Rescue Team said: “We have been made aware of pod of whales in the Greenock area.

These days, although they are no longer targeted on as large a scale, they are still killed in drive-hunts in the Faroe Islands. Like all marine mammals, they are protected under the Marine Mammal Protection Act. Their scientific name (Hyperoodon ampullatus) is derived from the Latin word ampulla for the bottle shape of their beak. Two of these teeth actually erupt at the tip of the lower jaw in males, but these aren’t always visible.

In Canada and Norway, these whales were hunted for meat and oil until the population was depleted. They have a bottle-shaped beak and a hooked dorsal fin, hence the “bottlenose” in their common name. Our research is also focused on acoustics—the physics of the properties of sound. On their undersides, their darker upper bodies are contrasted by pale, creamy flanks and bellies. Estimated up to 36.7 feet for males and up to 28.2 feet for females, Hunting, A world where every whale and dolphin is safe and free. Threats to this species include acoustic disturbance, oil and gas activities, entanglement in fishing gear, contaminants, changes to food supply, and vessel strikes. Estimating their exact weight has been difficult to determine due to a lack of data, however it is estimated that these whales can weigh between 13,000 – 17,000 lbs. The body is large and rotund with a small falcate (sickle shaped) or triangular dorsal fin, positioned far down the back.
