The '''horn shark''' (''Heterodontus francisci'') is a species of [[bullhead shark]], in the family Heterodontidae. It is [[endemism|endemic]] to the coastal waters off the western coast of [[North America]], from [[California]] to the [[Gulf of California]]. Young sharks are segregated spatially from the adults, with the former preferring deeper sandy flats and the latter preferring shallower rocky [[reef]]s or [[algae|algal]] beds. A small species typically measuring {{convert|1|m|ft|abbr=on}} in length, the horn shark can be recognized by a short, blunt head with ridges over its eyes, two high [[dorsal fin]]s with large spines, and a brown or gray coloration with many small dark spots.
