A HARP SEAL × HOODED SEAL HYBRID

Marine Mammal Science, 1997
AbstractIn this study we report the first documentation of mating between harp (Phoca groenlandica) and hooded seals (Cystophora cristata). The production of this hybrid was quite unusual, being the result of a cross between parents of different genera which are morphologically dissimilar and have quite different mating behavior and dramatically ...

Polioencephalomalacia in a juvenile hooded seal ( Cystophora cristata )

Veterinary Record, 2006
appeared grossly normal. No significant bacteria were recovered on microbiology and all the examinations for Brucella species were negative. Histological examination of coronal slices of the fore-, midand hindbrain and one sagittal slice of the cerebellum showed widespread lesions of polioencephalomalacia throughout the cerebrum.

The eye of the hooded seal,Cystophora cristata, in air and water

Journal of Comparative Physiology A, 1989
Multiple refractive state measurements were made on a male and female hooded seal (Cystophora cristata) when the eyes were exposed to air and to water. The measures, made by conventional retinoscopy and by photorefraction, show that the seals are moderately hyperopic (2-3 diopters) in water and moderately myopic (2-4 diopters) in air.

Vitamin D Metabolism in the Hooded Seal (Cystophora cristata)

The Journal of Nutrition, 1988
Fish-eating mammals, such as seals, appear to ingest levels of vitamin D that are toxic to most mammals. To determine how seals cope with high vitamin D intakes, the metabolism of tritiated cholecalciferol ([3H]D3) was investigated in hooded seal (Cystophora cristata) pups during their postweaning fast and pups and adults consuming herring alone or ...
