案例简介：尽管姥鲨是海洋中第二大的鱼类，但它们的猎物很小。他们吃浮游动物，特别喜欢一群叫做桡足类的微小甲壳类动物。在找到一个浮游动物斑块后，他们张开巨大的嘴，游过它，如 @ bertiegregory的视频所示。巨大的白色g拱门包含rakers-结构将浮游生物从通过嘴的水中捕获。与许多其他种类的滤食动物不同，它们能够将水泵过这些g鱼，而鲨鱼则被动进食。这意味着他们必须游泳吃。考虑到它们的巨大体型，它们需要做大量的进食-因此需要大量的游泳。据估计，他们每小时可以过滤200万升水!担心被这些温柔的巨人吞噬吗？虽然他们有一个三英尺宽的嘴巴，但他们的喉咙非常狭窄，所以即使他们想吞下一个人 (他们不想)，他们身体上也不能!# britishwildlife # 水下 # 自由潜水 # baskingshark # shark

案例简介：Although basking sharks are the second biggest fish in the sea, they have tiny prey. They eat zooplankton, with particular preference for a group of tiny crustaceans called copepods. After locating a zooplankton patch, they open their giant mouths and swim through it, as shown in this video by @bertiegregory. The huge white gill arches contain rakers—structures that snag plankton from the water that passes through the mouth. Unlike many other species of filter feeders that are able to pump water past these gill rakers, basking sharks feed passively. This means they must swim to eat. Given their huge size, they need to do a lot of eating—and therefore a lot of swimming. It’s estimated they can filter two million liters of water an hour! Concerned about being swallowed by these gentle giants? While they have a three-foot-wide mouth, their throats are incredibly narrow, so even if they wanted to swallow a person (which they don’t), they physically couldn’t!#britishwildlife #underwater #freediving #baskingshark #shark
