Delphinapterus leuca (Beluga whale)

1977
The karyotypes were donated by Dr. Deborah A. Duffield and come from lymphocyte cultures. The female karyotype is C-banded. The last pair of autosomes has distinct satellite with heteromorphic C-band.

Monitoring white whales (Delphinapterus leucas) with echolocation loggers

Polar Biology, 2012
Monitoring programmes for white whales (Delphinapterus leucas) have been called for repeatedly in recent years because this species is likely to be negatively impacted by climate change, but also because such a broadly dispersed, high trophic feeder can serve as an effective ecosystem sentinel.

Mandibular Layering in Delphinapterus leucas and Age Determination

Nature, 1969
LAWS1 investigated mandibular periosteal layers as an aid to ageing the Sperm whale Physeter catodon. Continued studies of P. catodon indicate that mandibular layers and tooth layers occur in equal numbers2, and it has been postulated that two tooth layers are deposited annually3. Two tooth and one mandibular layer in Delphinus delphis are annual4.

Herpes-like Viral Dermatitis in a Beluga Whale (Delphinapterus leucas)

Journal of Wildlife Diseases, 1989
Approximately 3.5 mo following its capture, a beluga whale (Delphinapterus leucas) developed focal pale gray skin lesions. These lesions persisted for at least 8 mo. A biopsy from one of these sites revealed epithelial intranuclear inclusions. Herpes-like viral particles were seen by transmission electron microscopy.

HEMATOLOGY AND SERUM CHEMISTRY VALUES IN THE BELUGA (DELPHINAPTERUS LEUCAS)

Journal of Wildlife Diseases, 1988
Normal values and ranges for 31 clinical hematology and serum chemistry tests are reported for the beluga or white whale (Delphinapterus leucas). The values were collected over a 6-yr period from eight belugas maintained for display at Sea World (San Diego, California, USA) facilities and represent long-term evaluations for each animal in a controlled ...

Bubbleblow in beluga whales (Delphinapterus leucas): a play activity?

Behavioural Processes, 1997
In Odontocetes, bubbleblow is reported in several ethograms but its function is poorly understood. For the five captive beluga whales (Delphinapterus leucas) of the Vancouver Public Aquarium, we recorded the occurrence of this behaviour, its diurnal pattern and individual variability.

Body Size in White Whales, Delphinapterus leucas

Journal of the Fisheries Research Board of Canada, 1969
Measurements of length, girth, and weight show that male white whales grow larger than females. The smallest white whales come from western Hudson Bay, the White Sea, and Bristol Bay, Alaska. Animals of intermediate size inhabit all other arctic Canadian localities sampled and also the St. Lawrence River and the Kara and Barents seas.

Age estimation of white whales (Delphinapterus leucas) from Greenland

Meddelelser om Grønland. Bioscience, 1994
Various techniques of displaying growth layer groups (GLGs) in teeth from white whales, Delphinapterus leucas, from Greenland were tested. The dentine and cementum in unprepared longitudinal thick sections (150-200μm) displayed under transmitted polarized light microscope generally provided the simplest and clearest display of GLGs.

Occurrence of butyltin compounds in beluga whales (Delphinapterus leucas)

Applied Organometallic Chemistry, 1998
Fifty-two beluga whale samples (Six liver samples, and 46 blubber samples including ones from different depths of the fat layer) from the St Lawrence River, Canada, were analyzed for butyltin compounds (mono-, di-, and tri-butyltin) with a view to investigating the occurrence and contamination of butyltin in these animals.
