== Anatomy and appearance == {{multiple image |align=left |direction=vertical |width= |image1=Carcharodon carcharias upper teeth.jpg |caption1=Upper teeth |image2=Carcharodon carcharias lower teeth.jpg |caption2=Lower teeth }} [[File:Carcharodon carcharias skeleton.jpg|thumb|Great white shark's skeleton]] The great white shark has a robust, large, conical snout. The upper and lower [[Lobe (anatomy)|lobes]] on the tail fin are approximately the same size which is similar to some [[mackerel shark]]s. A great white displays [[countershading]], by having a white underside and a grey dorsal area (sometimes in a brown or blue shade) that gives an overall mottled appearance. The coloration makes it difficult for prey to spot the shark because it breaks up the shark's outline when seen from the side. From above, the darker shade blends with the sea and from below it exposes a minimal silhouette against the sunlight.

However, these measurements were not obtained in a rigorous, scientifically valid manner, and researchers have questioned the reliability of these measurements for a long time, noting they were much larger than any other accurately reported sighting. Later studies proved these doubts to be well-founded. This New Brunswick shark may have been a misidentified [[basking shark]], as the two have similar body shapes. The question of the Port Fairy shark was settled in the 1970s when J. E. Randall examined the shark's jaws and <!--The following quote is taken verbatim from the source; please DO NOT change the wording or spelling.

Though rumours have stated this shark was exaggerated in size or non-existent altogether, witness accounts by the then young Craig Anthony Ferreira, a notable shark expert in South Africa, and his father indicate an unusually large animal of considerable size and power (though it remains uncertain just how massive the shark was as it escaped capture each time it was hooked).

One of these adaptations is a "[[rete mirabile]]" (Latin for "wonderful net"). This close web-like structure of veins and arteries, located along each lateral side of the shark, conserves heat by warming the cooler arterial blood with the venous blood that has been warmed by the working muscles.

Blood samples taken from forty-three individuals of varying size, age and sex off the South African coast led by biologists from the University of Miami in 2012 indicates that despite high levels of mercury, lead, and arsenic, there was no sign of raised white blood cell count and granulate to lymphocyte ratios, indicating the sharks had healthy immune systems.
