Diver's Time in Water Prior to Unprovoked Shark Attack
As you can see, many of the attacks on divers occurred less than one hour after entering the water. This is mostly due to the fact that divers do not spend as long in the water compared to other water activities. The next graphs depict the activities of divers being struck less than an hour after entry into the water and more than an hour after entry into the water. Of 45 cases (N=45).
Activities of Divers Struck Less Than an Hour After Entering Water
These are the relative percentages of divers who participate in the listed activities who were attacked less than an hour after entry into the water. Of 42 cases (N=42).
Activities of Divers Struck More Than an Hour After Entering Water
These are the relative percentages of divers who participate in the listed activities who were attacked over an hour after entering the water. Of 4 cases (N=4).
Time of Unprovoked Shark Attacks on Divers
This graph reflects the behavior patterns of humans. Nearly all shark attacks occur between 9:00 AM and 6:00 PM and during the weekend, NOT because of the shark's daily activity cycles, but because these are the times of the day when divers go out in the water. Of 109 cases (N=109).
Unprovoked Shark Attacks on Divers by Day of the Week
