California Sea Lion Trivia Questions

Males are much larger, reaching up to 850 pounds, while females max out around 220 pounds—a classic example of sexual dimorphism.

They belong to the Otariidae family (eared seals), distinct from true seals (Phocidae), with visible ear flaps and rotating hind flippers.

California sea lions typically hold their breath for up to 10 minutes, with dives usually lasting 3–5 minutes. The claim of 20 minutes is not supported by reliable sources.

California sea lions can survive in freshwater; they have been observed living in rivers and lakes for extended periods, obtaining water from their food and drinking freshwater directly.

Their vibrissae are highly sensitive to hydrodynamic trails, helping them locate prey even in murky or dark water.

Males develop a prominent sagittal crest on the crown of their skull, which becomes more pronounced with age and dominance.

They do not migrate long distances; most populations are resident along the Pacific coast, with some seasonal movement for breeding or food.

This is a common misconception; sea lions do not use tools. The marine mammal known for using rocks to crack open shellfish is the sea otter, not the California sea lion.
