The Great White Shark is one of nature’s greatest and most feared predators. Though not the ‘ferocious man-eater’
they are depicted to be in the blockbuster film Jaws, the great white shark is an intimidating creature with awesome power and speed. Enjoy the
20 incredible photographs below along with some interesting facts about this master of the sea.
The great white shark is very well known for its size, with the largest individuals known to have approached or exceeded
6 metres (20 ft) in length, and 2,268 kilograms (5,000 lb) in weight. It reaches maturity at around 15 years of age and
can have a life span of over 30 years.

Great white sharks live in almost all coastal and offshore waters which have water temperature between 12 and 24 °C
(54 and 75 °F), with greater concentrations in the United States (Atlantic Northeast and California), South Africa, Japan,
Australia (especially New South Wales and South Australia), New Zealand, Chile, and the Mediterranean. One of the
densest known populations is found around Dyer Island, South Africa

Great whites display countershading, 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.
Great white sharks are carnivorous, and prey upon fish (e.g. tuna, rays, other sharks), cetaceans (i.e., dolphins, porpoises, whales),Photograph by PIETER VISSER
pinnipeds (e.g. seals, fur seals, and sea lions), sea turtles, sea otters, and seabirds.

Great white sharks are ovoviviparous (eggs develop and hatch in the uterus, and continue to develop until birth).
The great white has an 11-month gestation period. The shark pup’s powerful jaws begin to develop in the first month.
The unborn sharks participate in intrauterine-cannibalism: stronger pups consume their weaker womb-mates.
Delivery is in spring and summer.
Although the great white is typically regarded as an apex predator (no predators of their own) in the wild, it is in
rare cases, preyed upon by the larger orca (also known as a killer whale). Interspecific competition between the
great white shark and the orca is probable in regions where dietary preferences of both species may overlap.

Beautiful, deadly and endangered. The tiger is all of these. Below you will find fascinating facts and incredible photographs of this magnificent animal.

The tiger is the largest of the four “big cats” (lions, jaguars, leopard and tigers) and is an apex predator, meaning it
resides at the top of their food chain with no predators of their own.

The larger tiger subspecies can reach up to 3.3 metres (11 ft) in total length, weighing up to 300 kilograms (660 pounds),
with canines up to 4 inches long.

Tigers are obligate carnivores, meaning they depend solely on the nutrients found in animal flesh.

Tigers are territorial and generally solitary animals, often requiring large contiguous areas of habitat that support their
prey demands. Coupled with the fact that they are indigenous to some of the more densely populated places on earth,
has caused significant conflicts with humans.

Three of the nine subspecies of modern tiger have gone extinct, and the remaining six are classified as endangered,
some critically so. The primary direct causes are habitat destruction, fragmentation, and hunting. The remaining
sub-species of tigers are: Bengal, Indochinese, Malayan, Sumatran, Siberian, and South China

Among the big cats, only the tiger and jaguar are strong swimmers; tigers are often found bathing in ponds, lakes,
and rivers. During the extreme heat of the day, they often cool off in pools. Tigers are excellent swimmers, and are
able to carry prey through the water.
