1. The concentration of halides in the ocean is approximately 0.5 M in chloride,
   1mM in bromide, and 1μM in iodide.


2. Marine organisms have incorporated halogen atoms into the structures of many of
   their metabolites:


3. For the marine organisms that make the metabolites, some of these molecules are
   part of defense mechanisms that serve to promote the species’ survival by
   deterring predators or inhibiting the growth of competing organisms.


4. For humans, the vast resource of marine natural products shows great potential as
   a source of new therapeutic agents.
