Marine Mammals of Hudson Strait the Following Marine Mammals Are Common to Hudson Strait, However, Other Species May Also Be Seen
Marine Mammals of Hudson Strait The following marine mammals are common to Hudson Strait, however, other species may also be seen. It’s possible for marine mammals to venture outside of their common habitats and may be seen elsewhere. Bowhead Whale Length: 13-19 m Appearance: Stocky, with large head. Blue-black body with white markings on the chin, belly and just forward of the tail. No dorsal fin or ridge. Two blow holes, no teeth, has baleen. Behaviour: Blow is V-shaped and bushy, reaching 6 m in height. Often alone but sometimes in groups of 2-10. Habitat: Leads and cracks in pack ice during winter and in open water during summer. Status: Special concern Beluga Whale Length: 4-5 m Appearance: Adults are almost entirely white with a tough dorsal ridge and no dorsal fin. Young are grey. Behaviour: Blow is low and hardly visible. Not much of the body is visible out of the water. Found in small groups, but sometimes hundreds to thousands during annual migrations. Habitat: Found in open water year-round. Prefer shallow coastal water during summer and water near pack ice in winter. Killer Whale Status: Endangered Length: 8-9 m Appearance: Black body with white throat, belly and underside and white spot behind eye. Triangular dorsal fin in the middle of the back. Male dorsal fin can be up to 2 m in high. Behaviour: Blow is tall and column shaped; approximately 4 m in height. Narwhal Typically form groups of 2-25. Length: 4-5 m Habitat: Coastal water and open seas, often in water less than 200 m depth. -

Blue Whale (Balaenoptera Musculus) Sightings Off the Coast of Virginia Dan T
Engelhaupt et al. Marine Biodiversity Records (2020) 13:6 https://doi.org/10.1186/s41200-020-00189-y MARINE RECORD Open Access Blue whale (Balaenoptera musculus) sightings off the coast of Virginia Dan T. Engelhaupt1*, Todd Pusser2, Jessica M. Aschettino1, Amy G. Engelhaupt3, Mark P. Cotter1, Michael F. Richlen1 and Joel T. Bell4 Abstract We report on two sightings of individual blue whales (Balaenoptera musculus) off the coast of Virginia during marine mammal surveys. On 11 April 2018, during a vessel survey off the coast of Virginia, a single blue whale was observed approximately 100 km east-northeast of Virginia Beach. On 10 February 2019, another single blue whale was recorded during an aerial survey approximately 135 km east-southeast of Virginia Beach. These observations mark the first time this endangered species has been documented with photographs off the coast of Virginia, and represent the southernmost confirmed sightings in waters of the United States Atlantic Exclusive Economic Zone (EEZ). At the time of the vessel observation, numerous fin whales (Balaenoptera physalus), humpback whales (Megaptera novaeangliae), and North Atlantic right whales (Eubalaena glacialis), were observed within the same approximately 8 km2 area as the blue whale. For the aerial sighting, the blue whale was seen feeding among at least 15 fin whales in an area approximately 4 km2. These sightings contribute to the small body of information existing for the late winter/early spring distribution of blue whales in waters of the western North Atlantic.

Variation of Bowhead Whale Progesterone Concentrations Across Demographic Groups and Sample Matrices

Abingdon St., Arlington, Virginia 22207, USA 3North Slope Borough, Department of Wildlife Management, PO Box 69, Barrow, Alaska 99723, USA ABSTRACT: Bowhead whale Balaena mysticetus progesterone concentrations were measured in different sample matrices (serum, blubber, and urine) to investigate (1) concordance among sam- ple type and (2) variation among life-history class. Samples were collected from subsistence- hunted whales (n = 86) taken from 1999 to 2009. In general, irrespective of sample matrix, preg- nant females had the highest concentrations by orders of magnitude, followed by mature animals of both sexes, and subadults had the lowest concentrations. Subadult males and females had sim- ilar progesterone concentrations in all sample matrices measured. When pregnant animals were included in our analyses, permuted regression models indicated a strong positive relationship between serum and blubber progesterone levels (r2 = 0.894, p = 0.0002). When pregnant animals were not included, we found no significant relationship between serum and blubber levels (r2 = 0.025, p = 0.224). These results suggest that progesterone concentrations are mirrored in these sample types over longer periods (i.e. -

Balaenoptera Bonaerensis – Antarctic Minke Whale
Balaenoptera bonaerensis – Antarctic Minke Whale compared to B. bonaerensis. This smaller form, termed the “Dwarf” Minke Whale, may be genetically different from B. bonaerensis, and more closely related to the North Pacific Minke Whales, and thus has been classified B. acutorostrata (Wada et al. 1991; IWC 2001). This taxonomic position, although somewhat controversial, has been accepted by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and the Convention on Migratory Species (CMS). Assessment Rationale The current IWC global estimate of abundance of Antarctic Dr. Meike Scheidat Minke Whales is about 500,000 individuals. The abundance estimates declined from about 700,000 for the second circumpolar set of abundance survey cruises Regional Red List status (2016) Least Concern* (1985/86 to 1990/91) to about 500,000 for the third National Red List status (2004) Least Concern (1991/92 to 2003/04). Although this decline was not statistically significant, the IWC Scientific Committee does Reasons for change No change consider these results to reflect a change. However, Global Red List status (2008) Data Deficient whether this change is genuine or attributed to greater proportions of pack ice limiting the survey extent, has not TOPS listing (NEMBA) (2007) None yet been determined. More detailed results from an CITES listing (1986) Appendix I assessment model are available for the mid-Indian to the mid-Pacific region, and suggest that the population Endemic No increased to a peak in 1970 and then declined, with it *Watch-list Data being unclear whether this decline has levelled off or is still continuing past 2000. -
