海峡群岛国家公园的巨藻

海峡群岛国家公园的巨藻,北美太平洋沿岸，高达100英尺的巨型海藻群为大量的鱼类、无脊椎动物和海洋哺乳动物提供了栖息地，就像今天照片里位于加利福尼亚海峡群岛的这片海藻一样。巨型海藻，准确地说是一种褐藻，是所有海藻中最大、生长最快的之一。它每天能生长两英尺！你在这张图片中看到像豆荚一样的气囊有助于海藻漂浮。正如亚马孙雨林的树木一样，海洋中的海藻群对海洋生物和海洋健康至关重要。

Channel Island National Marine Sanctuary, California, USA

All along the Pacific Coast of North America, giant stands of kelp up to 30.48 metres high, like this one in California ‘s Channel Islands, provide habitat for a vast number of fish, invertebrates, and sea mammals. Giant kelp, technically a type of brown algae, is the largest of all seaweed and one of the fastest growing of any organism, as much as 0.61 metres per day! The gas-filled pods you see in this image help the kelp float. Like the trees in the Amazon, the kelp forests of our oceans are key to the health of marine life and our oceans.
