California sea lions face multiple welfare threats including entanglement in fishing gear, domoic acid poisoning from harmful algal blooms, and population fluctuations driven by prey availability and climate change.
Domoic acid poisoning causes sea lions to strand on beaches in a state of neurological crisis - seizures, disorientation, and inability to navigate or feed. The experience is terrifying and painful. Sea lions caught in entangling debris develop wounds that cut progressively deeper as they grow, sometimes resulting in decapitation. Pups stranded during El Nino events are often severely malnourished, their mothers unable to find fish in warmer waters. The Marine Mammal Center and similar organizations perform extraordinary work rescuing and rehabilitating these animals, but the underlying causes - ocean warming, harmful algal bloom intensification, and marine debris - require systemic solutions.
