A team of researchers with NOAA Fisheries Service's Southwest Fisheries Science middle has found "compelling evidence" in the search for the reason behind record numbers of starving sea lion pups climbing out of the sea and onto California beaches. In their paper published in Royal Society Open Science,the team describes how their study of fish populations and hunting activities of pregnant sea lions off the coast of California, led to evidence that suggests the pups are starving because the main food source for their mothers has become scarcer.
