Sea lions are relatively common in certain parts of the world, especially in coastal regions with stable populations. However, their abundance can vary significantly by species and location.

Conservation efforts are in place to protect their populations and habitats. Some species of sea lions are threatened or endangered due to various factors such as habitat destruction, climate change, entanglement in fishing gear, and competition for food with commercial fisheries.

Climate change poses a significant threat to sea lions, affecting their habitats, food availability, and overall health. As sea levels rise, critical coastal habitats used for breeding, resting, and raising pups are at risk of being submerged.
