Maternal transfer of perfluoroalkyl substances in hooded seals
Environmental Toxicology and Chemistry, 2017 Abstract The role of milk in the transfer of perfluoroalkyl substances (PFASs) to offspring is not well known in wildlife. Eight PFASs were quantified in plasma and milk in mother–pup pairs of hooded seals (Cystophora cristata) during the nursing period, and the role of milk in the transfer process ...

The Bacterial Microbiome in the Small Intestine of Hooded Seals (Cystophora cristata) [PDF]
Microorganisms, 2020 Arctic hooded seals (Cystophora cristata) are monogastric carnivores that go through extreme fasting and re-feeding in early life. They are born isolated on sea ice; suckle high-fat milk for four days and may then fast for up to one month before they start hunting and feeding on small prey (fish and crustaceans).
