Horn Sharks in addition to Swell Sharks Behavior in addition to Interactions Thank You!! Questions

Grayson, Michael, Interim Music Director and Program Director has reference to this Academic Journal, PHwiki organized this Journal Research in addition to presentation done by: Amihan Arroyo, Anneka Christie, in addition to Alex Lopez Horn Sharks in addition to Swell Sharks Behavior in addition to Interactions Our Research Project Observing the Horn Shark in addition to Swell Shark in the touch tank on campus We wanted to see whether or not the amount of physical activity of both sharks changed due to time of day. Also, if they displayed different social behaviors at day or night. Our research question: Do the sharks in the tanks social interactions with other organisms change during different hours of the day The Swell Shark Cephaloscyllium ventriosum Habitat in addition to Region: Prefers kelp as long as ests, caves, rock crevices in addition to bottoms in order to hide. Found around the southern tip of Mexico, along Cali as long as nia’s coasts, in addition to in the Eastern Pacific. Diet: crustaceans in addition to fish Size: Can grow up to 3 feet When the swell shark feels threatened, it ‘swells’ up to twice its body size.

Heterodontus francisci Habitat in addition to Range: The Horn Shark lives in kelp as long as ests in addition to other habitats similar to the swell shark. This species can be found from Central Cali as long as nia to Baja Cali as long as nia Diet: mollusks, crustaceans, small fish, sea urchins Size: Can grow up to 4 feet The horns’ be as long as e each of their dorsal fins are actually spines. The Horn Shark Our Hypothesis We believe that the sharks in the touch tank will be more active during the night time. This is because we have background knowledge that both species of sharks are nocturnal animals. We are also curious to see which behaviors they exhibit during these hours, in addition to which organisms they interact with. Horn Shark Swell Shark Procedures Observed the sharks at touch tank as long as 15 minute intervals. Wrote down detailed observations about their activity. Logged in addition to organized collected in as long as mation daily

Controls in addition to Variables Due to the fact that our project was mostly observational, we didn’t have many controls or variable present in our research. Controls Sharks in tank (amount in addition to species) 15 minutes observations in a controlled habitat Variables time of day (independent) sharks activity in addition to location (dependent) External Factors Feeding times Unnatural lighting Veterinarian arrived on 6/28 between 9:00a.m.- 12:30p.m. Observations We concluded that both sharks were significantly more active at night. This means that our hypothesis was correct. We also noticed that both sharks had very different behavioral systems. The Swell Shark was a lot more tolerant of other organisms, while the Horn Shark was easily disturbed by other animals. While the Horn Shark’s activity slightly increased at night, it never reached the same level of activity as the Swell Shark. Why study this topic Significance We decided to research this particular project because we were looking as long as ward to learning more about these species. We hope our research will help scientists to study these sharks in captivity.

Things We Can Change To extend this experiment For night observations, determine if the presence of light effected their behavior. Research in their natural environment. Study sharks of different age in addition to gender to reflect the whole species. Study how sharks of the opposite sex interact with each other at different times during mating seasons.
