A disco four-on-the-floor with horn stabs on every bar is the easiest beat in pop to nod to, which is the whole point. ## Biological Superpowers & Stats - **Taxonomy**: *Zalophus californianus* - **Danger Level**: Medium - **Conservation Status**: Least Concern ([IUCN Red List](https://doi.org/10.2305/iucn.uk.2026-1.rlts.t41666a294651011.en)) - **Superpower**: One sea lion learned to bob its head in time with a rhythm, even complex music - **Habitat**: Coastal waters of the eastern North Pacific, from southeast Alaska to central Mexico - **Diet**: Squid, anchovies, mackerel, rockfish and sardines - **Tags**: mammal, eared-seal, carnivore, ocean, social, vocalist ## Natural History & Behavior ## A seal that barks like a dog California sea lions are "eared seals": unlike true seals, they have visible ear flaps, and they live along the West Coast of North America. Males bark like dogs to talk to other males and females, and the National Zoo calls them one of the noisiest pinniped species. So how does a mother find her pup in a crowd? > **Voice, then nose** > A mother and her pup trade calls unique to the pair. She can find her pup among hundreds of others by its call, then gives it a sniff as a final check. ## Bulls, cows and a bony crest The sexes differ a lot in size. Adult males average about 600 pounds (272 kilograms) and 8 feet (2.4 meters) long, and before the breeding season a male's weight often increases, to as much as 1,000 pounds (454 kilograms). Females average 220 pounds (100 kilograms) and about 6 feet (1.8 meters). Pups weigh about 18 pounds (8 kilograms) at birth. At about 5 years old, males develop a noticeable crest along the top of the skull. That bony ridge is called a sagittal crest, and it gives the head a high, domed forehead. Males start holding breeding territories at around 9 to 12 years old, and a territory may include up to 14 females. Bulls patrol it, barking, and fight if they must. In the wild a sea lion lives 15 to 20 years, and about 25 to 30 in human care. ## Fast, flexible hunters In the water their torpedo-shaped bodies can reach 25 to 30 mph (40 to 48 kph), twisting through tight turns as they chase fish. They eat a variety of prey, such as squid, anchovies, mackerel, rockfish and sardines, mostly feeding toward the top of the water column, though they can dive as deep as 1,000 feet if necessary. One common habit is "rafting": a sea lion holds its flippers above the water, motionless, for a long time, to rest and regulate its body temperature. It can look like an animal caught in a net. The species ranges from southeast Alaska to the Pacific coast of central Mexico. The main breeding range runs from the Channel Islands in southern California to central Mexico, and in normal years males migrate in winter to feeding areas off California, Oregon, Washington, British Columbia and southeast Alaska. The Red List rates the species Least Concern. ## A sea lion with rhythm Before a 2013 study, only vocal mimics, including humans, cockatoos and budgerigars, had been shown to keep a beat. Then a California sea lion learned to bob its head in time with an auditory rhythm. It carried that skill over to a range of novel tempos and to complex, musical stimuli. ## Frequently Asked Questions ### How big is a California sea lion? Males are the heavyweights: a National Zoo profile puts a grown male at an average of 600 pounds (272 kilograms), measuring about 8 feet (2.4 meters) from nose to tail. Adult females are much smaller and slimmer, at around 220 pounds (100 kilograms) on average and roughly 6 feet (1.8 meters) long. *(Source: [Smithsonian's National Zoo and Conservation Biology Institute]())* ### How fast and how deep can a California sea lion go? Speeds of 25 to 30 mph (40 to 48 kph) come quickly to them in the water. They usually feed high in the water column, but a sea lion can go down as far as 1,000 feet when it has to. *(Source: [Smithsonian's National Zoo and Conservation Biology Institute]())* ### How does a sea lion mother find her pup in a crowded colony? She listens, then sniffs. Mother and pup use calls that belong to the pair alone, and each also has a scent that identifies it. A mother homes in on her own pup's call among hundreds of others, and a sniff is her final check. *(Source: [NOAA Fisheries]())* ### Can a sea lion keep a beat? One did. In a 2013 study a California sea lion learned to nod in time to a beat, kept it up at speeds it had not been trained on, and moved in time to music. The authors concluded that keeping a beat may be more widespread in the animal kingdom than previously hypothesized. *(Source: [Cook et al. 2013]())* ## Sources 1. [California Sea Lion.
