size white shark

A typical adult great white shark measures 4 to 4.8 m (13 to 16 ft ) with a typical weight of 680 to 1,100 kg (1,500 to 2,450 lb ), females generally being larger than males. The maximum size of the great white shark has been subject to much debate, conjecture, and misinformation. Richard Ellis and John E. McCosker , both academic shark experts, devote a full chapter in their book, The Great White Shark (1991), to analysing various accounts of extreme size. Today, most experts contend that the great white shark's "normal" maximum size is about 6 m (20 ft), with a "normal" maximum weight of about 1,900 kg (4,200 lb). For several decades, many ichthyological works, as well as the Guinness Book of World Records , listed two great white sharks as the largest individuals caught: an 11 m (36 ft) great white captured in Southern Australian waters near Port Fairy in the 1870s, and an 11.3 m (37 ft) shark trapped in a herring weir in New Brunswick , Canada in the 1

Anatomy and appearance White Shark

The great white shark has a robust large conical-shaped snout . It has almost the same size upper and lower lobes on the tail fin (like most mackerel sharks , but unlike most other sharks). Great white sharks 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 colouration makes it difficult for prey to spot the shark because it breaks up the shark's outline when seen from a lateral perspective. When viewed from above, the darker shade blends in with the sea and when seen from below casts a minimal silhouette against the sunlight. Great white sharks, like many other sharks, have rows of teeth behind the main ones, allowing any that break off to be rapidly replaced. A great white shark's teeth are serrated and when the shark bites it will shake its head side to side and the teeth will act as a saw and tear off large chunks of flesh. Great white sharks often swallo

History Aquaculture,

Aquaculture has been used in China since circa 2500 BC. When the waters lowered after river floods, some fishes, mainly carp , were held in artificial lakes . Their brood were later fed using nymphs and silkworm feces, while the fish themselves were eaten as a source of protein . By a fortunate genetic mutation, this early domestication of carp led to the development of goldfish in the Tang Dynasty . The Hawaiian people practiced aquaculture by constructing fish ponds (see Hawaiian aquaculture ). A remarkable example from ancient Hawaii is the construction of a fish pond, dating from at least 1,000 years ago, at Alekoko . According to legend, it was constructed by the mythical Menehune . The Japanese practiced cultivation of seaweed by providing bamboo poles and, later, nets and oyster shells to serve as anchoring surfaces for spores . The Romans often bred fish in ponds. The practice of aquaculture gained prevalence in Europe during the Middle Ages , since fish were sca
