=== Breaching behaviour ===

A [[Whale surfacing behavior|breach]] is the result of a high-speed approach to the surface with the resulting momentum taking the shark partially or completely clear of the water. This is a hunting technique employed by great white sharks whilst hunting seals. This technique is often used on cape fur seals at [[Seal Island, South Africa|Seal Island]] in [[False Bay]], [[South Africa]]. Because the behaviour is unpredictable, it is very hard to document. It was first photographed by [[Chris Fallows]] and Rob Lawrence who developed the technique of towing a slow-moving seal decoy to trick the sharks to breach.<ref>{{cite web |url=http://www.elasmo-research.org/education/white_shark/breaching.htm |title=White Shark Breaching |publisher=ReefQuest Centre for Shark Research |access-date=18 April 2012 |author=Martin, R.

The seals swim on the surface and the great white sharks launch their predatory attack from the deeper water below. They can reach speeds of up to {{cvt|40|km/h|mph}} and can at times launch themselves more than {{cvt|10|ft|m|order=flip|0}} into the air. Just under half of observed breach attacks are successful.<ref>{{cite journal |last1=Martin |first1=R. A. |last2=Hammerschlag |first2=N. |last3=Collier |first3=R.

The crew were undertaking a [[animal population study|population study]] using sardines as bait, and the incident was judged not to be an attack on the boat but an accident.<ref>{{cite news |first=Xan |last=Rice |title=Great white shark jumps from sea into research boat |date=19 July 2011 |url=https://www.theguardian.com/world/2011/jul/19/great-white-shark-jumps-boat |work=[[The Guardian]] |access-date=20 July 2011 |quote=Marine researchers in South Africa had a narrow escape after a {{cvt|3|m|ft|0}} long great white shark breached the surface of the sea and leapt into their boat, becoming trapped on deck for more than an hour.
