1 DR. TEAL: Some of the corals, for example, are soft strip [words 



2 unclear] substrates. 



3 DR. HECKER: Same with the sponges. 



4 DR. TEAL: It's the same with the sponges. It seems to me it's 



5 fair to say if, for every 1,000 of them, 999 are in canyons, then you 



6 can say they live in the canyons. 



7 DR. HECKER: I recall some species canyon indicators. That does 



8 not mean that they are nowhere else. It's just when you've got them, 



9 you've got a good indication-- 



10 DR. KRAEUTER: Would it be useful, under your megafauna, to 



11 separate those forms which are truly attached to corals and things, to 



12 require a hard or firm substrate as opposed to the things that you were 



13 describing, the fish, lobsters, crabs? 



14 They can be substantially different in the way they go about 



15 things and stuff, so some of your--it's a splitting of the categories, 



16 to a certain extent, but when I think about fish, lobsters, crabs, 



17 mobile organisms, I think about them as substantially different in 



18 response to all sorts of things than those that are fixed. 



19 DR. HECKER: Sessile. 



20 DR. KRAEUTER: Sessile. 



21 DR. HECKER: But do you want a substrate distinction, because the 



22 sessiles are not just a single substrate? How fine do you want it 



23 broken down? That is the question? 



24 DR. KRAEUTER: I don't know. Up at the top, on the very top, 



25 you've got megafauna versus infauna. I was thinking megafauna really is 



26 two categories, that's what we are talking about here, the sessile and 



27 mobile. 



28 DR. COOPER: The sessile and the mobile. A number of your major 



29 mobile species of commercial importance-- 



30 DR. TEAL: If you are making a table, it isn't useful to break it 



31 down so much that nobody can find any information on it. 



32 DR. KRAEUTER: No. 



33 DR. HECKER: I was trying to give an overview.
