No, sharks are not a concern. The team understands the fear, but it is highly improbable to see a shark, let alone be attacked by one. Statistically speaking, you are more likely to be struck by lightning twice or hit on the head by a coconut than you are to be attacked by a shark. The area instructors take the students for surfing is over reef where an adult human can stand with their head and shoulders above water. These shallow waters are not where sharks tend to be found or even like to swim as they like to stay further out in deeper waters. Sharks will also not attack a human on purpose as we are not a food source that they are interested in which is why it is very rare to be attacked.
