Remarkable neuronal hypoxia tolerance in the deep-diving adult hooded seal (Cystophora cristata)

Neuroscience Letters, 2008
Seals cope with regular exposure to diving hypoxia by storing oxygen in blood and skeletal muscles and by limiting the distribution of blood-borne oxygen to all but the most hypoxia vulnerable tissues (brain, heart), through dramatic cardiovascular adjustments.

Sexual shape dimorphism in the skull of the hooded seal Cystophora cristata

Zoological Journal of the Linnean Society, 1986
Multiple-group principal component analysis was used to investigate morphological differences between skulls of male and female hooded seals. The scores on the first principal axis (PCI), calculated from the variance-covariance matrix of log-transformed data, were highly correlated with age and the component was interpreted as a general growth axis ...

Morphometric variation in the Hooded seal (Cystophora cristata)

Journal of Zoology, 1985
Intra‐ and intersexual variation in 16 skull dimensions and total body length of 233 aged Hooded seals caught in the north‐west Atlantic were investigated. Absolute growth was described by asymptotic growth curves applied to single dimensions, as well as to scores on the first principal component of logarithmically transformed cranial data, which are ...

Mating strategies in male hooded seals (Cystophora cristata)?

Canadian Journal of Zoology, 1990
Male attendance of females with pups was monitored in individually marked hooded seals, Cystophora cristata, during the breeding seasons of 1988 and 1989. Two patterns of attendance were observed. Some males remained relatively sedentary and defended a single female as long as she remained on the ice.
