Statistics of Shark Attacks on Divers


Clothing and Gear Worn Used by Divers During an Unprovoked Attack
(N=544 cases with at least one of the items listed below; individuals may be represented in more than one category)
Clothing And Gear Attacks (%) Number of Victims Using this Clothing/Gear
Face Mask With Or Without Snorkel 25 134
Swim Fins 21 116
Swimsuit 7 38
SCUBA 15 81
Weapon (ie., Knife, Speargun, or Powerhead) 10 57
Wet Suit/Dry Suit 10 53
Other Gear 8 41
Dive Bag/Stringer 3 14
Non Swim Clothing 1 5
Hard Hat Suit 1 5


The table above reflects the clothing and gear people commonly wear while diving. It is possible that certain clothing and gear make a human look more like natural prey, but no significant research has been done in this area. Facemasks are an example of a popular piece of gear that divers wear, not necessarily a piece of gear for which sharks attack divers.

clothes




pattern


The highest percentage of victims repported no special features on their clothing, while the next highest percentage of victims had highly contrasting colors on their outfits or gear. A possible explaination is that more of the population wears highly contrasting colors on their outfits and gear, or dive with no special features while less of the population swim with shiny features on their clothing and gear.

special


What you are looking at is the distribution of clothing patterns on the portion of the population that were attacked while diving. As you can see, most of the divers had no pattern on their swimsuits. This reflects divers' tastes in diving suit patterns more than tastes of sharks.

primary


secondary


tertiary

These are the distributions of primary, secondary, and tertiary colors on divers' clothes when they were attacked. A very large proportion of divers who were attacked by sharks wear black gear and clothing as a primary color; however, black is the most common color used by dive gear manufactures. It may also be possible that the human form looks more like natural prey, such as marine mammals, when dressed in dark colors.
