Abstract
A female scalloped hammerhead shark (Sphyrna lewini) conducted a species record deep dive to 1240 m in coastal-pelagic waters off Hawaii Island. This extends the deepest known depth range of the species by over 200 m (650 ft) and highlights the question of the extent to which deep-diving activity is mediated by physiological constraints, such as temperature and oxygen availability.
摘要
一条雌性皱唇鲨（Sphyrna lewini）在夏威夷岛沿海海域进行了一次创纪录的深海潜水，深度达到 1240 米。这将该物种已知的最深深度范围延长了 200 多米（650 英尺），并突出了一个问题，即深海潜水活动在多大程度上受到生理限制（如温度和氧气供应）的调节。
