Unlike the adults, juvenile horn sharks prefer a flat, sandy habitat. 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. At Santa Catalina Island, a 20-year warming trend has resulted in an increase in the horn shark population and a decrease in the swellshark population. Horn sharks are less common than swellsharks in the northern Channel Islands, where the water is cooler. [3] Biology and ecology [ edit ] Horn sharks rest during the day and only become active at night.
