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. -

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. -
The Bowhead Vs. the Gray Whale in Chukotkan Aboriginal Whaling IGOR I
ARCTIC VOL. 40, NO. 1 (MARCH 1987) P. 16-32 The Bowhead vs. the Gray Whale in Chukotkan Aboriginal Whaling IGOR I. KRUPNIK’ (Received 5 September 1984; accepted in revised form 22 July 1986) ABSTRACT. Active whaling for large baleen whales -mostly for bowhead (Balaena mysricetus) and gray whales (Eschrichrius robustus)-has been practiced by aborigines on the Chukotka Peninsula since at least the early centuries of the Christian era. Thehistory of native whaling off Chukotka may be divided into four periods according to the hunting methods used and the primary species pursued: ancient or aboriginal (from earliest times up to the second half of the 19th century); rraditional (second half of the 19th century to the1930s); transitional (late 1930s toearly 1960s); and modern (from the early 1960s). The data on bowhead/gray whale bone distribution in theruins of aboriginal coastal sites, available catch data from native settlements from the late 19th century and local oral tradition prove to be valuable sources for identifying specific areas of aboriginal whaling off Chukotka. Until the 1930s, bowhead whales generally predominated in the native catch; gray whales were hunted periodically or locally along restricted parts of the coast. Some 8-10 bowheads and 3-5 gray whales were killed on the average in a “good year”by Chukotka natives during the early 20th century. Around the mid-20th century, however, bowheads were completely replaced by gray whales. On the basis of this experience, the author believes that the substitution of gray whales for bowheads, proposed recently by conservationists for modemAlaska Eskimos, would be unsuccessful. -

NORTH ATLANTIC RIGHT WHALE Scientific Name: Eubalaena
Common Name: NORTH ATLANTIC RIGHT WHALE Scientific Name: Eubalaena glacialis Müeller Other Commonly Used Names: Northern right whale, right whale Previously Used Names: Balaena glacialis Family: Balaenidae Rarity Ranks: G1/S1 State Legal Status: Endangered Federal Legal Status: Endangered Description: North Atlantic right whales are robust baleen whales weighing as much as 63 metric tons (70 U.S. tons) and growing upwards of 15 meters (50 feet) in length. Newborn calves are approximately 4 meters (13 feet) long at birth. Distinctive characteristics include a strongly arched lower jaw, no dorsal fin, a V-shaped blow when the whale surfaces to breathe, large white patches on the head (callosities), paddle-shaped flippers, and a large head that may exceed one fourth of total body length. Most right whales are uniformly black, but some individuals have areas of white pigmentation on the belly. Two rows of black baleen plates up to 2.5 meters (8 feet) in length grow from the roof of the mouth . Each baleen plate is fringed with fine hair-like structures that enable the whales to filter plankton from the surrounding water. Right whale callosities are areas of raised, jagged skin located near the whale’s blowhole, eyes, rostrum, lip- line, and chin. The callosities are black in color but appear white because they are colonized by populations of white amphipod crustaceans called cyamids or “whale lice.” Each right whale has a unique callosity pattern, enabling scientists to distinguish individuals. Similar Species: Three species of right whales inhabit the world’s temperate oceans: the North Atlantic right whale, the North Pacific right whale (Eubalaena japonica), and the southern right whale (E. -

The Aerial Surveys of Arctic 19 Marine Mammals (ASAMM) project provides information on distribution, behavior, and relative density of marine 20 mammals. ASAMM surveys large areas of bowhead whale and killer whale summer and autumn habitat and offers 21 consistent information on bowhead whale carcasses. Thirty-three bowhead whale carcasses were documented in 22 July–October, from 2009 to 2018. Carcasses were distributed across the eastern Chukchi and western Beaufort seas 23 from 141.6° W to 168.1° W and 68.9° N to 72.0° N. -
Southern Right Whale Recovery Plan 2005
SOUTHERN RIGHT WHALE RECOVERY PLAN 2005 - 2010 The southern right whale (Eubalaena australis) is listed as endangered under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). This plan outlines the measures necessary to ensure recovery of the Australian population of southern right whales and is set out in accordance with Part 13, Division 5 of the EPBC Act. Objectives for recovery The objectives are: • the recovery of the southern right whale population utilising Australian waters so that the population can be considered secure in the wild; • a distribution of southern right whales utilising Australian waters that is similar to the pre- exploitation distribution of the species; and • to maintain the protection of southern right whales from human threats. For the purposes of this plan ‘secure in the wild’ is defined qualitatively, recognising that stricter definitions are not yet available, but will be refined and where possible quantified during the life of this plan by work currently underway and identified in the actions of this plan. ‘Secure in the wild’ with respect to southern right whales in Australian waters means: a population with sufficient geographic range and distribution, abundance, and genetic diversity to provide a stable population over long time scales. Criteria to measure performance of the plan against the objectives It is not anticipated that the objectives for recovery will be achieved during the life of this plan. However, the following criteria can be used to measure the ongoing performance of this plan against the objectives: 1. the Australian population of southern right whales continued to recover at, or close to, the optimum biological rate (understood to be approximately 7% per annum at the commencement of this plan); 2. -
Species Assessment for North Atlantic Right Whale
Species Status Assessment Class: Mammalia Family: Balaenidae Scientific Name: Eubalaena glacialis Common Name: North Atlantic right whale Species synopsis: The North Atlantic right whale, which was first listed as endangered under the Endangered Species Act in 1973, is considered to be critically endangered (Clapham et al 1999, NMFS 2013). The western population of North Atlantic right whales (NARWs or simply right whales) has seen a recent slight increase. The most recent stock assessment gives a minimum population size of 444 animals with a growth rate of 2.6% per year (NMFS 2013). It is believed that the actual number of right whales is about 500 animals (Pettis 2011, L. Crowe, pers. comm.). At this time, the species includes whales in the North Pacific and the North Atlantic oceans (NMFS 2005). However, recent genetic evidence showed that there were at least three separate lineages of right whales, and there are now three separate species that are recognized. These three species include: the North Atlantic right whale (Eubalaena glacialis), which ranges in the North Atlantic Ocean; the North Pacific right whale (Eubalaena japonica), which ranges in the North Pacific Ocean; and the southern right whale (Eubalaena australis), which ranges throughout the Southern Hemisphere (NMFS 2005). The distribution of right whales is partially determined by the presence of its prey, which consists of copepods and krill (Baumgartner et al 2003). Most of the population migrates in the winter to calving grounds from in low latitudes from high latitude feeding grounds in the spring and summer. A portion of the population does not migrate to the calving grounds during the winter and it is unknown where they occur during that season (NMFS website, NMFS 2013). -
