- They began to take whales that had washed up on the Californian coast and tow them out sea and then sink them in deep waters.
- Chemosynthetic bacteria take O2 from the seawater to oxidize the sulfide, generating energy for growth.
- The researchers concluded that the early whales were not yet large enough to host sulfophilic communities.
- ⦁ Whale skeleton were found under the surface of the sea.
- ⦁ A single dead whale can nourish a specialized ecosystem that lasts for decades.
- ⦁ Species similar to those whale falls may have depended on dead marine reptiles for hundreds of millions of years.
- ⦁ Bacteria can sometimes form the basis of entire ecosystem.
- ⦁ Smith and his co-workers to suggest in 1989 that whale skeletons might act as “stepping-stones” for deep-sea animals to spread from one chemosynthetic community to another.
- ⦁Whales that are washed up on the CA coast and tow them out of the sea then sink them in deep waters to counteract the buoyancy of decomposition gasses.
- ⦁Most whales are negatively buoyant when they die and thus sink rather than get beached.
- ⦁A dead whale that sinks to the seafloor brings a sudden bonanza of food to the dark, desert like expanse.
- Animals feed on leftover scraps of meat and blubber and on whale oil that has soaked the surrounding sediment.
- In 2008, a research group from Japan and Poland reported the discovery of bones of two plesiosaur skeletons originally around 10 meters long with associated provident snail specimens from upper Cretaceous rocks in Japan.
Summary:
In the article, it talks about how they found a 20 meter long whale skeleton buried in the bottom of the sea. When whales are dead, they would throw it under the sea then it will sink. After it sinks, many organisms underwater will it the dead whale body and sharks gets like bites. A single dead whale can nourish a specialized ecosystem that lasts for decades. But bacteria can sometimes form the basis of entire ecosystem. Animals fee on leftover scraps of meat and blubber and whale oil that has soaked the surrounding sediment.

Reflection:
After reading this article, it showed me how whales that dies are thrown back to the ocean and sink to the surface and feeds many organisms. I was shock to know that the duration is up to 2 years. I thought it wouldn't last that long because there are many organisms on the bottom of the sea. It is a good way to feed organisms but it would be really sad if whales go extincts.
