This fish is called a chimaera, and is rarely seen. We don't know 

 anything about how common it is. It may be important in potential 

 food chain transfer of radioactive materials from the deep sea or it 

 may not be. What is noteworthy is that we didn't catch any of 

 these fish in our trawl nets. This fish was only observed directly 

 from the submersible. I think an important consideration in deep- 

 sea monitoring, both now and in the immediate future, is that just 

 because you go out and conduct trawls or other sorts of sampling 

 doesn't mean you are really sampling all the different kinds of 

 organisms that are in the dumpsite area. 



If you do trawl, you probably won't catch the chimaerid fish, For 

 example. You won't catch the fast-swimming fish. You may only 

 get a very small cross-section of what is in that dump site. 



So, even using existing technology today, you may not be able to 

 predict all the food-chain transport mechanisms.
