Jaws made them famous overnight but what do you know about great white sharks?

 The Great White Shark AKA White Death With its ferocity earning it the moniker of “white death,” the great white shark is one of the most ferocious predators found in the ocean. Choosing to live in coastal, marine areas, this giant hunts and feeds upon fish, marine mammals and even birds, whenever caught! It is known to attack humans, even though it prefers other prey and only does so when provoked, or if no other feeding option is present.

 

How Big is the Great White Shark? 

 Gigantic in size, the largest measured specimens had a total length of 20 feet [6 meters] and weighed-in at a massive 5,000 lb. [approx. 2,270 kilogram] mark! The average length of a Great White Shark is between 13 and 17 feet long.

Would you Swim with Sharks ? 

The great white sharks like to live in coastal and offshore areas that have temperatures ranging between 12 – 24o C [54 - 75 o F]: Atlantic Northeast and California [USA]; Dyer Island [South Africa]; New South Wales and South Australia [Australia]; New Zealand; Japan; and some parts of the Mediterranean, where occasional specimens have been spotted.

 Known for their vociferous appetites, great white sharks prefer large hunting grounds frequented by other fish and mammals such as seals and dolphins. Their success as predatory animals is due to a number of reasons.

The Great White Sharks Diet

Like all other sharks, great white sharks can sense minuscule amounts of electricity produced by organisms, right down to half a billionth of a volt! Movement by an organism generates a tiny amount of electricity and the great whites, using their body’s lateral lines can pick it up. This allows them to home in on their prey without the prey being alarmed. Evolutionary adaption has also given them the strange ability to regulate their body temperatures: some parts are kept warmer by blood flow whereas the rest of the body remains at sea temperature. Their body coloring also works in camouflaging them by giving them an overall mottled appearance. And the sleek lines of their bodies allow them to move very fast, virtually undetected by the hapless prey until they move in for the kill.

Scary great white shark image - Just look at those teeth ! 

They have around 3000 teeth! These are on lots of rows. The front 2 rows are used to grab and cut prey . The other rows of teeth are used when the front ones drop out or are broken or worn.

Another Interesting Fact - They do swim a lot! 

Great white sharks are also prodigious swimmers and scientists have been able to track journeys of over 20,000 kilometers undertaken within a year! That is a whole lot of distance to cover on round trips from coasts of South Africa to Australia.

The Fins...... 


The fin that you can see in the pictures below and is usually the first indication of a shark is the dorsal fin. They also have 2 fins on their sides which are called pectoral fins.

Fishing Humor

There have been many claims of larger Great White Sharks, among them a 41.2 foot Great White Shark caught by a fishing trawler at Azores Island. Most of these stupendous claims have never been proved....some got Guinness record status only to be removed in later editions.

So would you like to see a great white shark up close?

No way, I wouldn't get close to anything with that many teeth.... 
or
Yeah, if protected by a shark cage
