Once the prey is drawn into the mouth, it is secured with the sharp front teeth and then ground into pieces by the flat lateral teeth. The scientific name for this species has been given erroneously as Heterodontus californicus. [5] Horn sharks maintain small home ranges of around 1,000 m2 (11,000 sq ft), which they may remain faithful to for over a decade, returning to the same shelter every day. Juveniles feed primarily on polychaete worms, sea anemones, and small clams, and have been known to "pounce" on anemones to bite off tentacles before they can be retracted.

Meanwhile, the blue shark, a pelagic species that prefers squid and fish, captures its prey by piercing it with knife-like teeth. [3], The relative abundances of the horn shark and the swellshark (Centroscyllim ventriosum), which shares the same habitat, are negatively correlated because horn sharks prefer temperatures warmer than 20 °C (68 °F) while swellsharks are more cold-tolerant.
