During certain times of the year (like now through October in Hawaii) Tiger Sharks may utilize specific areas to pup (give birth) mate, or hunt a seasonal prey item. Ancient Hawaiians knew theses seasons when sightings were more common. Kahu Manō where the “shark keepers” the ones who would seek them out and spend time with them like ohana (family.) Being aware and respectful of times and places can reduce or increase your chances of an encounter. Looking around constantly when you are in their domain/home/hale is one way to help encourage chances of a more peaceful encounter. If approached by a tiger shark on the surface they have a round snout that can be leveraged off of but it is more ideal to push flat handed on top of the head with a locked elbow to push yourself up, over, and behind, should you need to deter a large shark and slowly move towards your exit if you are not with an experienced guide.
