🔬 物种简介
剑鱼以其扁平坚硬的剑形上颌著称，用于劈砍猎物鱼群而非刺穿。白天独居于深水层休息，夜间上浮捕食。游速极快，肌肉含有特殊产热机制，能维持大脑和眼睛的温度高于水温，极大提升了在冷水层的感知能力。
Wikipedia
The swordfish, also known as the broadbill in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill. They are the sole member of the family Xiphiidae. They are a popular sport fish of the billfish category. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,878 m (9,442 ft). They commonly reach 3 m (10 ft) in length, and the maximum reported is 4.55 m in length and 650 kg (1,430 lb) in weight.
