The Narwhal, Monodon monoceros, in Eastern Canadian Waters

Journal of the Fisheries Research Board of Canada, 1975
In the Pond Inlet area of Baffin Island in 1963–65, 62 narwhals (Monodon monoceros) were caught in nets and examined. Growth layers occur in both the extruded tusk and in the embedded tooth. The few identifiable food remains in stomachs were of squid and Arctic cod. At birth, the calf measures about 160 cm in length and weighs just over 80 kg.

Movements of narwhals (Monodon monoceros) from Admiralty Inlet monitored by satellite telemetry [PDF]

open access: possiblePolar Biology, 2008
Twenty-one narwhals tagged in 2003 and 2004 in Admiralty Inlet showed a different summer distributional pattern than previous narwhal-tracking studies from Somerset Island, Eclipse Sound and Melville Bay. The migration of the narwhals tracked from Admiralty Inlet moved out through Lancaster Sound 15 days earlier (P < 0.0001) than the narwhals summering

THE CHROMOSOME COMPLEMENT OF THE NARWHAL (Monodon monoceros)

Canadian Journal of Genetics and Cytology, 1973
The karyotype of a male narwhal (Monodon monoceros) is described. The chromosome number was found to be 2n = 44. The karyotype is similar to all other whale species reported except that of the sperm whale (Physeter catodon), and the killer whale (Orcinus orca).The findings presented here add further support to the concept that the whales may be ...

Trace element and stable isotope analysis elucidate stock structure in a narwhal (Monodon monoceros) population with no genetic substructure

Canadian Journal of Zoology, 2019
Chemical composition of tissues can act as a biological tag to discriminate among groups of animals that inhabit different areas. In Canada, subsistence hunting of the Baffin Bay narwhal (Monodon monoceros Linnaeus, 1758) population is managed as stocks ...

On the Stomach of the Narwhal (Monodon monoceros)

Proceedings of the Royal Society of Edinburgh, 1890
Although numerous most admirable descriptions of the stomach of various species of Delphinidae (the family of toothed Whales to which the Narwhal belongs) have from time to time appeared from the pens of most able observers (of whom a list will be found in the references appended), we have found it impossible to find anything more than a mere ...

Some characteristics of narwhal,Monodon monoceros, diving behaviour in Baffin Bay

Canadian Journal of Zoology, 1995
Dive data were collected from nine narwhals, Monodon monoceros, instrumented with satellite-linked dive recorders in northwest Greenland in August–September 1993 and 1994. Data were collected for periods ranging from a few weeks to 9 months. The narwhals made daily dives to depths of more than 500 m and frequently dived to 1000 m or more. However, most

The narwhal (Monodon monoceros) cementum–dentin junction: A functionally graded biointerphase

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2014
In nature, an interface between dissimilar tissues is often bridged by a graded zone, and provides functional properties at a whole organ level. A perfect example is a “biological interphase” between stratified cementum and dentin of a narwhal tooth.

Underwater acoustic signals of the narwhal (Monodon monoceros)

Canadian Journal of Zoology, 1978
Underwater sound recordings of the narwhal from northern Baffin Island are analyzed and described. Frequency ranges of pulsed and pure tone vocalizations are found to be somewhat greater than previously observed. An earlier report that narwhals generate exclusively narrowband sounds is confirmed.

The manus of the Narwhal,Monodon monocerosL.

Proceedings of the Zoological Society of London, 1954
SummaryThe flipper of the Narwhal has been investigated in foetal and adult stages, with special reference to the carpus.In the foetus, radiale, intermedium and ulnare, a single centrale, trapezoid, magnum and separate distal carpals 4 and 5 are present. There is no trace of a pisiform or of a trapezium. The centrale fuses with the intermedium.
