📖 1. 概览
体长6m以上、体重超过2吨,是现存最大的肉食性鱼类。它具有将肌肉温度维持在高于海水温度的温血性(内温性,Endothermy)。
🌐 Wikipedia 摘要摘录The great white shark, also known as the white shark, white pointer, or great white, is a large shark. It is closely related to the mako sharks, the porbeagle, and the salmon shark. It is a robustly built species with a grayish upperside and a white underside. The white shark is one of the largest living shark and fish species, though it is still smaller than the whale shark and basking shark. It has about 300 triangular, serrated teeth that are continuously replaced. Its massive, fatty liver can reach over a quarter of its body weight, providing buoyancy and storing energy. The species is partially warm-blooded, an adaptation that allows it to remain active in colder waters.
🦴 2. 身体结构与特征
它能用吻端的“罗伦氏壶腹(劳伦氏器官)”感知生物心跳产生的微弱磁场,300颗锯齿状牙齿在一生中会更新替换数万颗。
🔍 3. 生态与行为
猎食海豹时,它会施展跃水(Breaching)捕猎法,从深海垂直冲刺,整个身躯跃出水面。
🇰🇷 4. 与韩国的关联
在韩国西海、南海、东海沿岸的水温上升期也有出没,已成为海洋安全研究的对象。
