A movie like Jaws leads numerous people today to believe that the Great White Shark is definitely an indiscriminate killer with sturdy taste for human flesh. In realistic contrast, investigation and observation have revealed nicely developed, non-human dietary preferences. Their diets depend on several elements: the age/size from the shark, place, and availability of prey.



Several scientists assume that white sharks start consuming even just before they are born. With no placenta, the sharks that develop the quickest eat the unfertilized eggs of their would-be siblings. This is called oophagy (egg consuming). The surviving sharks are totally formed at birth and ready to hunt efficiently. The diet of a juvenile shark differs from that of an adult, consisting of prey which is a lot easier to catch and acceptable to their size. In extra shallow waters they feed on invertebrates, smaller sized sharks, rays, fish, and the occasional unlucky sea bird.

As they come to be adults, the great white's diet expands to include things like marine mammals. They now possess the size/strength to successfully attack dolphins, also as seals and sea lions (identified also as pinnipeds). Despite the fact that they nevertheless sometimes eat fish for instance tuna or mackerel, these marine mammals turn into the preferred food source as a consequence of their higher fat content. Places with the globe with huge pinniped populations (Guadalupe Island in Mexico, South Africa, Australia, and considerably on the California coastline) are called highly concentrated great white shark locations as well. These places would be the greatest for scientists and shark enthusiasts to observe the feeding behavior of great whites, from boat decks or submergible shark cages.

Great white sharks also eat carrion, usually seen feeding on floating whale carcasses. This can be a pretty powerful solution to obtain a higher volume of fat-rich meat, without having to expend substantially energy or risking the injuries that may very well be incurred although attacking a reside seal. An incredibly large meal can sustain an adult shark for up to 1.5 months. Young where do great white sharks live are not capable to eat as significantly meals at a single time, so they must eat much more often.

Despite the fact that it's true that humans have been attacked by great whites, these attacks are rare. Generally they result from curiosity or mistaken identity on the element of your shark, in areas where the recreational activities of folks overlap with prey populations. When the attacks have resulted in fatalities, the victims most normally died as result of shock and huge blood loss from one initial bite, as an alternative to having been consumed as an attractive food supply.

This identical curiosity by the sharks leads them to occasionally swallow odd things. Some fishermen and scientists have reported finding exciting objects in the stomach of a terrific white from time to time, like a cuckoo clock, glass bottles, cans, lobster traps, boots, as well as a hat! In spite of what Hollywood and folklore would like us to think, human body parts are virtually by no means amongst the stomach contents.
