International Journal for Parasitology: Parasites and Wildlife, 2018 Harbour seals (Phoca vitulina) and grey seals (Halichoerus grypus) are final hosts of acanthocephalans in the German North and Baltic Seas. Parasitic infections in seals can cause pathological changes, which may result in deteriorated health of the host.

Diversity of late Neogene Monachinae (Carnivora, Phocidae) from the North Atlantic, with the description of two new species [PDF]
, 2018 While the diversity of 'southern seals', or Monachinae, in the North Atlantic realm is currently limited to the Mediterranean monk seal, Monachus monachus, their diversity was much higher during the late Miocene and Pliocene.

Extinct Pleistocene carnivores were diurnal and highly active
Ecography, Volume 2025, Issue 12, December 2025.There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...

Introducing FAMM: An Open‐Access Database of Fossil Arctic Marine Mammals
Global Ecology and Biogeography, Volume 34, Issue 9, September 2025.ABSTRACT Motivation The Arctic is currently experiencing the strongest effects of climate change on Earth. These effects, including sea ice loss, are already modifying the ecologies of the 11 species of marine mammals found in the Arctic year‐round.

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.Due to the massive hunting by humans, the number of spotted seals has decreased dramatically. This study used the ICPMS method to conduct experiments and analysed the correlation between heavy metal accumulations in the bodies of naturally grown spotted seals in the Bohai Sea and artificially raised spotted seals in aquariums and water samples.

The histology of retinas from the pinnipedia
Vision Research, 1970 Abstract The cellular components, receptors, bipolar and ganglion cells of retinas from several species of pinnipeds (seals and sea lions) were quantified. No area centralis was seen in any specimen. Only rod shaped receptors were observed. Ratios of these receptors to ganglion cells were determined and found to be similar to estimates of human ...

Papers in Palaeontology, Volume 11, Issue 2, March/April 2025.Abstract The Squalodontidae are one of the most historic families within the Cetacea, given that Squalodon was first named in 1840. Since Squalodon's initial description, workers in the 1800s were eager to assign heterodont cetacean teeth to this family; as a result, it became a wastebasket with many species based on fragmentary remains.
