Pinnipeds (seals and related species) use their whiskers to explore their environment and
locate their prey. Today they live mostly in marine habitats and are adapted for a highly …

Seal lice (Echinophthirius horridus) are bloodsucking ectoparasites of phocid seals and
vectors of pathogens like the heartworm, Acanthocheilonema spirocauda. Grey and harbour …

The earliest phocid seals evolved 30–24 million years ago (Ma) in the western North
Atlantic. There remains uncertainty in evolutionary relationships, with molecular data …

Hydrofoil‐shaped limbs (flipper‐hydrofoils) have evolved independently several times in
secondarily marine tetrapods and generally fall into two functional categories:(1) those that …

Today, monachine seals display the largest body sizes in pinnipeds. However, the evolution
of larger body sizes has been difficult to assess due to the murky taxonomic status of fossil …

The repeated returns of vertebrates to the marine ecosystems since the Triassic serve as an
evolutionary model to understand macroevolutionary change. Here we investigate the …

Modern pinnipeds (true and eared seals) employ two radically different swimming styles,
with true seals (phocids) propelling themselves primarily with their hindlimbs, whereas …

ABSTRACT A nearly complete skull and limited postcrania (SDSNH 146624), from the upper
Oligocene of the Pysht Formation (Clallam County, Washington State, USA), represent a …

Cooperative feeding is often observed among predators with strong social bonds; however,
it is unexpected in solitary predators. During 2016, several mass predation events were …

Otarioids (fur seals, sea lions and the walrus, Odobenus rosmarus) are an ancient group of
marine mammals that have adapted to feeding in water in a variety of ways. Fur seals and …
