Shark sightings in Oahu, Hawaii

I was in Oahu, Hawaii last week. I was fortunate to see a couple of white-tipped reef sharks under a ledge off of Waikiki. I also got to see several sharks in the aquarium at the Sea Life Aquarium at Waimanalo, including a stingray and a hammerhead shark. I even got to stroke the tail of a white-tipped reef shark in the touch pool there.
