Food limitation of sea lion pups and the decline of forage off central and southern California [PDF]
Royal Society Open Science, 2016 California sea lions increased from approximately 50 000 to 340 000 animals in the last 40 years, and their pups are starving and stranding on beaches in southern California, raising questions about the adequacy of their food supply.

Phylogenomic characterization of California sea lion adenovirus-1
Infection, Genetics and Evolution, 2015 Significant adenoviral diversity has been found in humans, but in domestic and wild animals the number of identified viruses is lower. Here we present the complete genome of a recently discovered mastadenovirus, California sea lion adenovirus 1 (CSLAdV-1) isolated from California sea lions (Zalophus californianus), an important pathogen associated with

Velocity Field Measurements of the California Sea Lion Propulsive Stroke Using Bubble PIV
Fluids, 2021 California sea lions are among the most agile of swimming mammals. Most marine mammals swim with their hind appendages—flippers or flukes, depending on the species—whereas sea lions use their foreflippers for propulsion and maneuvering.
