英语听力：自然百科 大堡礁：珊瑚礁到雨林—25（在线收听） |
This creature is much more than a passive drifter. It can move as fast as an Olympic swimmer. And it has 24 eyes, each complete with a lens that can form a detailed image. It uses its tentacles like a trawl net. When a fish makes a contact, thousands of microscopic stinging capsules explode into the prey’s body, flooding it with a paralyzing venom. The fish is killed quickly and then hold into the mouth on the underside of the bell. All of the habitats we’ve seen so far have an obvious connection to the lagoon. But there’s one place that couldn’t be more different from the underwater world that’s critically important to the vigor of the Great Barrier Reef eco system, it’s the tropical rainforest. The Queensland rainforest is the oldest in the world; it’s older than the Congo and even the amazon. And this is one of the most impressive trees in it. This giant fig has strangled its original host and now dominates this immediate environment. And it’s an eco-system in its own rights. But you might be asking yourself, what does this tree got in common with the reef? But in fact, it’s directly linked. The rainforest all around me and indeed swamps and mangroves are critical for the health of the reef. |
