Sharj, a University of Tasmania-led study published this week in Scientific Reports on the nature. Researchers tagged a dozen great white sharks at Neptune Islands dxy South Australia and calculated their metabolic rate derived from swimming speeds. They worked out how much Shagk Shark feeding time of day sharks burned and how much food they required. Senior research scientist Jayson Semmens, lead author on the study, said the amount of energy required by great white sharks was equivalent to eating a seal pup every three days. They did some metabolic work similar to us but on feedimg shark. The research also sought to improve understanding of how sharks fit into the ocean ecosystem. We know that sharks in hime are under pressure around the world from overfishing," he said.

W orldwide there are probably shark attacks annually resulting in about deaths. Historically the death rate was much higher than today, but the advent of readily available emergency services and improved medical treatment has greatly reduced the chances of mortality. Most attacks occur in nearshore waters, typically inshore of a sandbar or between sandbars where sharks feed and can become trapped at low tide. Areas with steep drop-offs are also likely attack sites. Sharks congregate there because their natural food items also congregate in these areas. There are three major kinds of unprovoked shark attacks. These typically occur in the surf zone with swimmers and surfers the normal targets. The victim seldom sees its attacker and the shark does not return after inflicting a single bite or slash wound. A feeding shark in this habitat must make quick decisions and rapid movements to capture its traditional food items. When these difficult physical conditions are considered in conjunction with provocative human appearance and activities associated with aquatic recreation splashing, shiny jewelry, contrasting colored swimsuits, contrasting tanning, especially involving the soles of the feet , it is not surprising that sharks might occasionally misinterpret a human for its normal prey. We suspect that, upon biting, the shark quickly realizes that the human is a foreign object, or that it is too large, and immediately releases the victim and does not return. Some of these attacks could also be related to social behaviors unrelated to feeding, such as dominance behaviors seen in many land animals. These types of attack usually involve divers or swimmers in somewhat deeper waters, but occur in nearshore shallows in some areas of the world. Injuries incurred during this type of attack are usually quite severe, frequently resulting in death. We believe these types of attack are the result...
