Megalodon Shark Could Eat Great White in a Few Bites, Research Claims_我的网站

一 | 　　今天（16日）上午，水利部举行会商，分析研判全国的防汛形势，截至今天9时，浙江、上海、江苏、安徽、河南、黑龙江、内蒙古等地52条河流仍维持超警，最大超警幅度4.27米，其中28条河流维持超保。 Scientists from the University of Zurich scanned the vertebrae and dentition of a megalodon (Otodus megalodon). The reconstructed mega-fish died at age 46, approximately 18 million years ago.,“It would be a superpredator just dominating its ecosystem,” co-author of the study John Hutchinson said. “There is nothing really matching it.”,It reached a length of about 16 meters and weighed more than 61 tons. According to the simulation, the maximum swimming speed reached 1.4 meters per second. The shark had to eat food with a total value of 98 thousand calories per day. Whale oil was very likely an important source of these calories.,The volume of the predator's stomach could reach almost 10 thousand liters. As a result, scientists came to the conclusion that the megalodon could travel long distances and was able to eat prey the size of a modern great white shark, the biggest predator in the ocean.,Megalodons that lived in the Miocene and Pliocene (23-3 million years ago) were the largest sharks that ever existed. Today, their giant teeth are often found; they're big enough to cover the palm of your hand. However, skeletons consisting of cartilage rarely fossilize, so they have not reached our days in such numbers as the teeth.。　　据预报，8月16日至17日，受降雨及上游来水影响，太湖水位将维持缓涨，长江下游支流滁河、淮河中游支流沙颍河、黑龙江干流同江以下江段仍将维持超警；四川岷江、青衣江等河流将出现涨水过程；暴雨区内部分中小河流可能发生超警洪水。16日8时至17日8时，四川中北部发生山洪灾害的可能性大，发布山洪橙色预警。
