Learn / Endangered / Northern Bottlenose Whale
The Northern Bottlenose Whale is a toothed whale that can be found in the northern parts of the Atlantic Ocean. It is a brownish-gray colour with a bulging forehead, a pronounced beak, and muscular physique.
There are two populations in Canadian waters: the Baffin-Labrador population, off the coast of Labrador, and the Scotian shelf population, off the coast of Nova Scotia.
Diet
Most of its diet is made up of deep-water squid. In addition, it consumes a variety of fish and benthic invertebrates.
Size
Adults average 8.8 m in length and have an average mass of 4,900 kg.
Population
It is challenging to assess the whale's population due to its concentrated population areas, deep diving behaviour, and tendency to approach ships. According to most estimates, there are currently between 15,000 and 40,000.
Scientific Name
Hyperoodon ampullatusr
Conservation Status
COSEWIC Status of the Scotian Shelf population “SSP”): Endangered
SARA Status of the SSP: Endangered
Habitat & Range
The northern bottlenose whale only inhabits the northern parts of the North Atlantic, primarily the waters off Norway, Spitzbergen, Iceland, Greenland, and Labrador. At the mouth of the Gully, a shallow canyon on the edge of the Scotian Shelf, northern bottlenose whale sightings are regular throughout the year.
Northern bottlenose whales prefer cold, deep waters (more than 1,000 metres). Particular concentrations are frequently observed close to regions where the ocean floor is particularly inclined

THREATS
The northern bottlenose whale still faces a number of risks despite the fact that humans are no longer hunting them. The killer whale is now its principal predator. Although some individuals become entangled in fishnets, the threat is typically rated as low or unknown. Human-caused contaminants and oil spills can also be harmful.
Another big concern is noise pollution. Due to its reliance on sound for foraging, navigation, and communication, the northern bottlenose whale can be negatively impacted by loud human activities. These activities can include military drills, oil and gas drilling, and navy sonar.
CURRENT PROTECTIONS
Northern bottlenose whales are protected from hunting by both national and international laws. Additionally, a number of initiatives have been launched to protect the Gully population.
In order to prevent shipping related to the development from interfering with the whales, the oil company Lasmo, which is using the Cohasset-Panuke field 110 km to the west of the Gully, has designated a “tanker exclusion zone” that includes the Gully.
For the northern bottlenose whales, the Department of Fisheries and Oceans has created a “Whale Sanctuary” in the Gully. The Gully is to be avoided at all costs or should be navigated with caution.
The Canadian Wildlife Service, the Department of Fisheries and Oceans, Parks Canada, World Wildlife Fund Canada, and other organizations are taking into consideration the formation of a Marine Protected Area in the Gully.
