The major argument against Porites that still remains is the notable 
absense of any genomic resourses for this coral, whereas there are 
already some ESTs for others  - Acropora palmata (4017), Montastraea 
faveolata (2156) and Acropora millepora (promised to be made available 
soon  from David Miller's lab). Also, there are already some microarrays 
developed for A. millepora.  Those corals have a head-start and seem to 
be favorites, so why betting on a dark horse?..

The arguments in favor of Porites which I recall from the previous 
discussion are:

1. Porites as a genus is an important reef builder both in Caribbean and 
2. It is not considered particularly endangered anywhere, so there is 
minimal concern about field sampling (quite unlike A. palmata, for example)
3. grows rapidly
4. easy to handle and keep in the lab
5. transmits its symbionts vertically, so there must be minimal genetic 
and gene expression variation due to zooxanthellae (I think this one is 
really important for genomics)
6. is easier for biochemistry and molecular work that Acropora and 
Monstastrea (according to Craig Downs).

Another concern that I received is that since Porites lobata is not a 
branching type it will be difficult to separate pieces (nubbins) for 
experiments; but here I was simply unfortunate to encounter a reviewer 
who did not try it with Porites and does not know how easy it is to saw 
its soft skeleton into neat chunks of any size required (as well as to 
saw off a larger piece in the field, for that matter). Let's disregard 
this one.
