Realistically for any scientist, it'll probably take at
least a few months to hone in on specific ideas or game plans. Once you start tracking down suitable references, and the next step, refining references from
those references, there will a lengthy *correspondence period* with various researchers, government officials, and facility managers to:
-verify that no one else has already done said research (wouldn't that suck?)
-that said research is legal and feasible given resources, expertise, and time
-correct inevitable stupid assumptions and answer inevitable stupid questions (I hate this part but it is tremendously important)
-update you on most current news (ongoing research, corrections, science changes, etc...)
So you have PLENTY OF TIME.
The "physiological to pharmacological" slant is actually a pretty good choice, and quite popular (particularly in central in south america). It allows you to focus on very specific taxa, and even better, only narrow attributes of such taxa. Off the top of my head, there's ongoing pharmacological research with:
-sunscreens (mostly corals or algae I think)
-painkillers (cone and turrid snails, jellyfish)
-anticancer
-sponges (for something I cannot recall)
Not being a biochemist, I have no idea how you people do any of this stuff. All I know is, it's a solid field and most researchers are lab flunkies limited by their ability to collect wild specimens. Ha, maybe you can track down some of these labs and become a local "supplier" for in-demand Caribbean fauna. After all,
somebody has to have the collecting permits.
