David Gallo on life in the deep oceans

Summary
According to “On life in the Ocean”, David Gallo presented that there many species live in the deep ocean. Seventy five percent of our planet is covered by oceans. Volcano is easy to be found in the ocean. Species always face the danger of exploring. Whereas, there are many species are live beside the volcano. He told us the stories in the sea, in the water of the ocean. In the sediments and the rocks of the sea floor. It is an incredible story. When we look back in those sediments and rocks, is a record of Earth history. Everything on this planet works by cycles and rhythms. The continents move apart, they come back tighter. Glaciers come and go. We are learning almost like a symphony. You cannot listen to a five billion year-long. It is absurd. We find out where this planet’s going at all the different. Scaled and work with it. We learn to manage it.
Response
I strongly agree with Professor David’s idea about learn almost like symphony. I am very fond of the species in the deep ocean. I have not seen those animals in the museum. Even in the science study. There were too many new units I have not seen yet. As an example is tubeworm,” each individual tubeworm consists of a soft body surrounded by a tough outer tube of whitish chitin (the same substance that makes up the shells of lobsters and crabs). This tube supports the inner body and protects it from predators (in some species, the tube is leathery, in other species, it is hard). Like plants, adult tubeworms are sessile: they are anchored to one spot, although their top end can move around in the water and can be withdrawn into the tube. Some tubeworms even have "roots": extensions of their body that extend into the sediment” (Venture deep Ocean). They may only live in five years. Sometimes it will die in several months because of volcano explosion. It infers our life. We cannot change the history. We only go with follow. Life like this; easy to live but weak to all species.
