Great
White Sharks & Surfing & Diving
Surfboard
changes have increased Great White Shark attacks.
Short Boards introduced in 1972 changed how the surfer looked to
the shark. Now surfers paddling and sitting on their boards look
just like a seal's silhouette. Instead of the long board, that didn't
look like the outline of a seal, sea lion or walrus. Great Whites
will often attack when the Seal, Sea Lion or Walrus is on it's ascent
for air or at the surface.
The Great White doesn't like humans and usually will stop attacking
after they taste them. Humans don't have the blubber they are after.
A large Great White can go without eating a couple months after
consuming one big meal of blubber.
Even though the Great White doesn't like the taste of Humans, that
first taste can be really deadly. While diving, attacks often happen
as they do with Seal, Sea Lions or Walrus, on the ascent. The surfacing
skin or SCUBA diver resembles that of a Seal, Sea Lion or Walrus
ascending.
There are other dangerous sharks (Blue, Mako & Hammerhead),
but the Great White is the one to watch for off California.
Sharks rely on visual information before attacking. This is the
principle behind the old ink dye shark repellents. They can sense
small amounts of blood from great distances, but still rely on a
visual ID of the target before attacking.
