Taxonomic name: Carcharodon
The most notorious of all sharks is the Great White Shark (Carcharodon
carcharias). Its colour is light to dark grey on the back, fading to pale
grey on the sides, sometimes with a bronzy sheen in certain light. The
belly is white and the underside of the large pectoral fins may be dusky
at the tips and/or have a dark spot near the body. This shark's conical
snout is usually heavily scarred from the defences of their prey and the
large eyes are pure black. The mouth remains partially open with the bottom
teeth always visible. Very broad caudal keels sit before an almost symmetrical
lunate tail. (see words to know)For such a notorious character, it is
perhaps surprising that no serious studies of this shark's natural history
have been undertaken until recently. It was not until 1985 that the first
pregnant female was reliably recorded. She had seven near-term embryos,
each about one metre long and weighing 13 kg. Studies of their feeding
habits show that only the larger Great White Sharks regularly prey on
marine mammals, such as seals and dolphins, their main diet consisting
of fish, particularly tuna, and smaller sharks.
Great White sharks are now protected in many countries, including some
States in Australia. Their low birth rate has not kept up with the numbers
being caught by sport and commercial fishing vessels. Most Great White
Sharks are killed accidentally in nets set for other species.
The maximum size for a Great White Shark is a subject of great controversy,
with exaggeration being the yardstick. Despite stories of mythical Great
Whites 10 m long, the largest specimen reliably measured to date has been
6.4 m long.
